Nematodes against sedges

From 372 SEK

Nematodes to combat crane fly larvae in the lawn. For outdoor use. Available in packages of 50 million or 250 million. Orders placed by Sunday evening are shipped the following Tuesday. When facing damage in the lawn caused by crane fly larvae, nematodes are used as a biological control. Nematodes are microscopic roundworms that are watered over the area you wish to treat. They are sold in packages containing 50 million or 250 million nematodes, where the smaller package is enough to treat 50-100 m² and the larger one 300-500 m². The marsh crane fly, Tipula paludosa, is common in Sweden. The adult insects hatch at the end of July and swarm over the lawn roughly until mid-September. During this period, egg-laying takes place. Each female can lay 300-400 eggs in the grass. The eggs hatch about 14 days after being laid, that is in August-September. The young larvae then crawl down under the grass roots, where they begin to gnaw on fresh root tips. The larvae overwinter in the soil and usually do not cause visible damage until the following spring. Then they grow large, reaching a length of 3-4 cm, and have a great need for food. The infestation is recognized by the grass dying or not growing properly. By examining the grass roots, one can find frayed gnaw marks. In severe infestations during spring, gnawing can also occur on the blades. Often the damage is also visible because birds have discovered the larvae and systematically start turning up the grass with their beaks to reach and eat them. When the nematodes are watered into the soil, they actively seek a suitable host in the form of a crane fly larva. They penetrate it and infect it. Bacteria from the nematodes kill the larva. The nematodes reproduce inside the infected larva and then leave it to search for new larvae. Treatment times Plan the first treatment about 2-3 weeks after the flight of adult crane flies has been observed over the grass (= egg-laying), this is usually in August/September. Nematodes mainly combat the small, newly hatched larval stages of the crane flies. Since nematodes also depend on warmth in the soil to work, they are most effective during a short period. This is in the autumn, up to early September. The following spring, the larvae are often too large for the nematodes to effectively control them. Treatment can also be done in spring when soil temperatures are above 8°C, but a reduced effect should be expected. Instructions for use The contents of the bag are dissolved in water while stirring, and then watered over the surface. Use the nematode solution immediately after mixing. Use nematodes only during the suitable treatment period to achieve an effective result. The treatment is mainly effective against the smaller larval stages of the crane fly. Optimal soil temperature is above 12 degrees for four weeks after treatment to ensure that the nematodes remain active. At lower temperatures, or with larger larval stages, a reduced effect can be expected. Since nematodes live in the water film between soil particles, it is important that the soil is kept moist during treatment. If the treatment area is dry, water it preventively before treatment. Also water after treatment to wash the nematodes well down into the soil. The surface should then be kept moist for at least two weeks after treatment. Treatment should not be done during heavy rain as it may risk washing away the nematodes. Nematodes should be watered out early in the morning, in the evening, or on a cloudy day, as they are sensitive to UV light. Tip!

Nematodes against ear weevils

From 212 SEK

Beneficial animals for controlling earwig larvae. For outdoor use. Available in packages of 10 million or 50 million. Orders placed by Sunday evening are shipped the following Tuesday. The nematodes (Heterorhabditis sp.) are delivered in quantities of 10 million or 50 million in a mixture of fine clay. Nematodes, also called roundworms, are microscopically small. They occur naturally in the soil, but usually not in sufficient numbers. After diluting the product in water, the nematodes actively search the soil for earwig larvae. When a larva is found, it is infected by the nematodes and dies. Infected larvae turn ochre-colored. The dead larva then serves as a kind of “shell” where the nematodes multiply. These nematodes can only live on insect larvae and therefore do not harm plants. Treatment times Since only the larval stages of the earwig are infected by the nematodes, it is important to coordinate treatment times with the earwig larva’s life cycle. In the garden and other treated areas, treatment can be done in May/June and in August/September. Instructions for use Use when the soil temperature is between 12 and 25°C for effective treatment. The contents of the bag are dissolved in water and watered onto the soil around the affected plants. The week after treatment, the soil should be kept lightly moist. 10 million is enough for treating about 10-20 m², and 50 million for about 50-100 m². Follow up the control The control of earwig larvae is very effective, but since the adult earwigs can live for over a year, eggs will continue to be laid during the first year. Therefore, collect any adult earwigs at night using a lantern, and monitor the control in the soil. Two to three weeks after treatment, you should be able to find dead brown larvae along the roots of the plant. Tip!

Nematodes against Garden Borers

From 372 SEK

Beneficial animals to combat garden chafer larvae in the lawn. For outdoor use. Available in packages of 50 million or 250 million. Orders placed by Sunday evening are shipped the following Tuesday. Larvae of the garden chafer, Phyllopertha horticola, can cause significant damage to the lawn. However, they can be controlled with the help of nematodes, microscopic roundworms, which are watered over the grass surface. They are sold in packages containing 50 million or 250 million nematodes, enough to treat 50-100 m² or 300-500 m² respectively. The adult garden chafers are usually seen during May-June, and only for a short period, when they lay their eggs in the grass. A characteristic of the garden chafer is flying low over the grass on sunny mornings. The eggs laid begin to hatch from June onwards. It is the larvae that cause damage to the lawn, as they feed on the grass roots. They grow during the season and overwinter in the soil. The following spring they pupate into a new generation of adult garden chafers. The garden chafer larva feeds on the grass roots near the surface. The grass becomes dry and yellowish and may start to loosen from the soil surface. The larvae also attract birds and other animals, which can further damage the lawn as they dig around in the grass searching for food. When the nematodes are watered into the soil, they actively seek a suitable host in the form of a garden chafer larva. They penetrate it and infect it. Bacteria from the nematodes kill the larva. The nematodes reproduce inside the infected larva and then leave it to search for new larvae. Treatment times The optimal treatment time is from late July to mid-September. During this period, the larvae are small and close to the surface near the grass roots. Treat about 4 weeks after observing the adult insects to catch the first larvae as the eggs hatch. Nematodes mainly combat the small, newly hatched larval stages of the garden chafers. Since nematodes also depend on warmth in the soil to work, they are most effective during a shorter period in summer and early autumn. Instructions for use The contents of the bag are dissolved in water while stirring, and then watered over the surface. Use the nematode solution immediately after mixing. Use the nematodes only during the suitable treatment period to achieve an effective result. The treatment is mainly effective against the smaller larval stages of the garden chafer. Optimal soil temperature is above 12 degrees for four weeks after treatment to ensure the nematodes remain active. At lower temperatures, or with larger larval stages, reduced effectiveness can be expected. Since nematodes live in the water film between soil particles, it is important that the soil is kept moist during treatment. If the treatment area is dry, water it preventively before treatment. Also water after treatment to wash the nematodes properly into the soil. The surface should then be kept moist for at least two weeks after treatment. Treatment should not be done during heavy rain as it may risk washing away the nematodes.

Beneficial Microterys against Pseudomonas aeruginosa

284 SEK

Beneficial animal against infestation by the false scale insect, Coccus hesperidum. The parasitic tick is not effective against other scale insect species, so it is important to determine the species of scale insect causing the infestation. In a pack of 25 pieces. The product cannot be ordered during the winter. Orders placed by Sunday evening will be shipped the following Tuesday. Scale infestations can be difficult to control. It is not always easy to spot scale insects as they are stuck in one place. Their colour can blend in well with the plant and hide on stems and leaf veins. The first sign of infestation is often the honeydew secreted by the scale insects. It leaves a sticky film on and around the plant, for example on the window or window sill. In the honeydew, sooty mold fungi can easily grow, which gives the plant a black coating. Scale insects suck plant sap, like other lice. The infestation can lead to discoloured leaves and stunted growth. Scale insects, unlike aphids, are immobile for almost their entire life. As small larvae, they find a suitable place on the plant where they then suck their food. Characteristic for them is the "shield" they have over their body. It protects and makes them difficult to fight. Under the shield, the female can lay up to thousands of eggs. The larvae then crawl out to find their own places on the plant to attach themselves to. There are many different species of scale insects. They can be divided into "true scale insects" and "false scale insects". The different groups are distinguished by the fact that the true scale insects have an external shield that can be removed from the body. The false scale insects do not have an external shield, instead their dorsal skin grows and hardens, forming a shield. This is attached to the louse and cannot be removed from the body. When biologically controlling scale insects, it is very important to determine which species of scale insect is causing the infestation. The beneficial insects are host-specific and will not parasitize any species other than the one they are adapted to. One of the most common scale species on houseplants is the orange wax scale, Coccus hesperidum, a so-called false scale. The "shield" is yellowish-brown transparent, often with a darker "H"-like pattern in color. It is flat and asymmetrically oval, about 3-5 mm in size. It is often located near leaf veins, but can also be found on leaf stalks and young shoots. This species generally secretes a lot of honeydew. Examples of plants it attacks are citrus plants, ivy, ficus, laurel and camellia. The host plants are often woody. For biological control of the orange wax scale, Coccus hesperidum , the parasitic wasp Microterys is used flavus / nietneri . It is an approximately 2 mm long stingray with a yellowish/brownish body and black and white striped antennae. The wasp lays eggs inside the scale insect, and the larva lives there for all five larval stages. As an adult, it then eats its way out of the scale insect through a small round hole, which can be seen from above if you look closely. The wasp lays about 10 eggs a day, during the two months that are their maximum lifespan. The adult wasps also eat the scale insect, a process known as host feeding. Microterys actively seeks out scale insects on infested plants. It takes middle and older stages of the orange wax scale insect. When Microterys is only effective against the orange wax scale, Coccus hesperidum , it is very important to identify the species of scale infesting your plants. If it is a different species of scale, Microterys will not be effective. User manual To To be able to combat Microterys effectively, certain conditions need to be met. Release should only take place between March and October. The parasitic wasp needs a long day, meaning that the day consists of more light hours than dark hours. For the stingray to be active, a temperature of at least 20 degrees is required. Temperature has a major impact on the stingray's development time. At 25°C, development from egg to adult takes about 23 days. Recommended dosage is 5-10 pieces/plant. Treatment is done 1-2 times, two weeks apart. The package is opened at the infested plants, the stingers seek out the scale insects themselves. Treat all plants that have had contact with the infested plant. For example, all those that have been in the same window. Thoroughly wash the surface where the infested plant has been, such as the windowsill and window. Follow the treatment It may be difficult to see a clear effect of the treatment, as the scale insects still remain on the plant after Microterys has parasitized it. After 10-14 days (depending on temperature), a dark ring can be distinguished on closer observation under the "shield" of the aphid. These are the excrement of the parasitic scale, which then indicates that the scale has become parasitized. At a later stage, the exit hole from the adult parasitic scale can also be discovered as a small, round hole in the "shield". In the event of successful treatment, the new shoots and petioles that are formed should be free from infestation.

Beneficial animal mix against "whiteflies" / mealybugs

Beneficial animal against mealybug/"white fly" infestation, in packs of 500 or 1000 pieces. The product cannot be ordered during the winter. Orders placed by Sunday evening will be shipped the following Tuesday. <div class="modules m-product trailing-trip" data-controller="9"> <div class="m-product m-product-additional-info"> <div class="toggle-content t-panel-clean m-product-additional-info-content"> <div class="pane active m-product-additional-info description clearfix" id="tabs-pane1"> <div class="ck-content" data-controller="description"> The parasitic wasp, Encarsia formosa , is about 1 mm long and yellow and black in color. They are delivered as pupae glued to a card, in packs of 500 or 1000. These pupae are called “black scales” and during the first week the pupae hatch by the parasitic scales gnawing their way out through a small hole. The hatched parasitic wasp actively searches for larvae of “white flies” to parasitize. They lay their eggs inside the host larvae (which are white). After about 14 days, these parasitized larvae turn black. After another 14 days, adult parasitic wasps hatch from the puparia. Encarsia formosa only lay eggs in the last larval stages of "white flies", they do not kill adults. Fully grown individuals can live up to 4 weeks and will therefore fly around and lay new eggs even if livestock has been released. It may therefore be an advantage to treat with insecticidal soap before the parasitic wasps are released. The desired temperature when setting out is above 17°C. User manual The parasitic wasp is delivered as black pupae glued to cardboard. The box with the cards is opened only when the plants are infested. Hang the cards on the plants, protected from sunlight. Follow the fight In the following weeks, there should be more and more “black pupae” on the plants in relation to the mealybug larvae. However, it may be necessary to spray the plant tops lightly with, for example, insecticidal soap to reduce the number of adults. </div> </div> </div> </div> </div>

Beneficial animal mix against aphids

212 SEK

A mixture of gall midges (approx. 200) and parasitic wasps (approx. 100) against aphid infestations. Orders placed by Sunday evening will be shipped the following Tuesday. Aphid gall midge (Aphidoletes aphidimyza) The mixture contains gall midge pupae. From the pupae, adult gall midges hatch and fly out to find colonies of aphids, where they lay small red eggs. When the eggs hatch, a reddish larva (about 5 mm long) emerges. It is a real predator that kills and sucks out a large number of aphids. After about a week, it pupates in the soil, where it remains for 14 days, and so a new cycle of gall midges continues. The aphid parasitic weevil ( Aphidius colemani ) The parasitic wasp is delivered as a mixture of cocoons and adult parasitic wasps. The parasitic wasp searches for aphids and lays eggs inside them. After about 10 days, the aphid swells up and turns into a gray-brown cocoon, remaining attached to the plant. It almost resembles papier-mâché. After about 2 weeks, a new parasitic wasp gnaws its way out of the cocoon and is ready to find new aphids. User manual In case of heavy infestations, it is advantageous to give the plant a good shower of water or insecticidal soap before releasing the beneficial insects. The box with beneficial insects is first opened outside in the greenhouse near the infested plants. Place the box under the plants in the shade, for example under a clay pot (with holes in it). From here the insects take over the control. Follow the fight The larvae of the aphid gall midge leave dead, sucked aphid shells, which can be seen on the plant. Cocoons of parasitized aphids from the parasitic wasp are visible after about 14 days. If you look at the parasitized aphid with a magnifying glass, you can see a hole. This is a newly hatched parasitic wasp that has cut itself out of the aphid.

Orius beetles against thrips, mealybugs, aphids, spider mites, etc.

From 212 SEK

<div class="m-product-short-description ck-content clearfix" data-controller="description--short" itemprop="description"> Beneficial insect effective against thrips, both adults and nymphs. Available in packs of 100 or 500. Orders placed by Sunday evening will be shipped the following Tuesday. Orius majusculus is a Swedish species of the genus Orius in the family Orius beetles. Orius beetles are the most effective beneficial insects that can be released against thrips, they take both adults and all larval stages of most thrips species. Orius beetles primarily eat thrips. An adult beetle can ingest 20 thrips a day, but they can also eat other pests such as spider mites, dwarf mites, aphids and mealybugs. If you only have an infestation of pests other than thrips, you should instead use beneficial insects that effectively target those pests. Product description The Orius beetles are delivered in a package with a mixture of adults and nymphs distributed in buckwheat husks. It is available in sizes of 100 or 500. When attacking, about 5-10 rams/m 2 are used. How many rams you need depends on how many and how big the plants are, and the size of the attack. If the attack is severe on a large number of plants, many rams are needed, and for minor attacks and few plants, a smaller amount can be sufficient. Generally speaking, it is better to release the rams in several rounds than to release many at one time. However, note that there are some, more unusual, tropical thrips species that are difficult to control, where neither beneficial animals nor chemicals have a good effect. They often come home with the houseplants, are dark in color and sometimes have white stripes. One example is Echinothrips, which is particularly difficult to control. User manual The Orius beetles are sprinkled on the foliage of plants with thrips infestation. For plants with narrow leaves, or where it is otherwise difficult to place the beneficial insects on the leaves, you can buy bioboxes to hang on the plant ( see related product below ). Alternatively, make your own paper cones that you pour the beetles into and place on the plants. The adult beetles can fly and spread easily in the plants. The nymphs can walk between the plants as long as the leaves touch each other. The Orius beetles are sometimes difficult to find among the plants, as they like to hide in the nooks and crannies and in the buckwheat husks they are transported with. Orius beetles can be used both outside in the greenhouse and indoors. Indoors they do not seek out pantries, bedding or similar, but since they can fly, it is a matter of taste whether you wish to use them inside. It is not recommended to use them outdoors as they will easily fly away. Orius beetles are active at temperatures between about 16°C and 35°C. They can also survive on pollen from flowering plants. Therefore, flowering plants can be an advantage when using Orius. Long day lengths, over 14 hours per day, are necessary for Orius to reproduce, but they also survive shorter day lengths. Orius beetles are sensitive to various pesticides and one should therefore be careful with release after using, for example, provado/provanto sticks. The plants can be sprayed with soap before releasing Orius, in which case it needs to have dried up before release. Feel free to combine Orius with a set of <a href="https://shop.nyttodjur.se/shop/11-vita-flygare---mjolloss/10-gula-klisterskivor/" target="_blank">yellow sticky discs</a> . You can also combine with <a href="https://shop.nyttodjur.se/shop/11-vita-flygare---mjolloss/49-swirskii-rovkvalster/" target="_blank">swirskii predatory mites</a> or <a href="https://shop.nyttodjur.se/shop/15-trips/17-tripsrovkvalster/" target="_blank">thrips predatory mites</a> in small bags. They work well as a complement to Orius and as a preventative against new infestations, for example after completing treatment with Orius. Storage Orius should be distributed to the plants immediately upon receipt. In case of emergency, they can be stored for a couple of days at 8-10°C. </div>

<div data-controller="description--short" class="m-product-short-description ck-content clearfix" itemprop="description"> Swirskii mites, beneficial against young stages of mealybugs (whiteflies) and thrips. In a pack of 10 small bags. Orders placed by Sunday evening will be shipped the following Tuesday. Protect your plants against thrips and whitefly attacks with swirskii predatory mites. Amblyseius ( Typhlodromips ) swirskii is a predatory mite about 0.5 mm in size that is used preventively and in the initial stages of attacks by several pests. They mainly take thrips and mealybugs (whiteflies), but in the absence of other food they can also take spider mites and survive on pollen. Swirskii are mobile and spread quickly across plants as long as the leaves touch each other. They can change in color from dark red to light yellow, depending on what they feed on. For example, if they eat mealybugs and thrips, they become more orange in color. Predatory mites like warm and humid conditions and work best at temperatures above 18 degrees. The optimal temperature is 25-28°C, but they can handle both cooler and warmer temperatures. If the temperature drops below 15 degrees, the predatory mite becomes inactive. Swirskii mainly feeds on the younger life stages of both thrips and mealybugs. They can eat up to 5 thrips larvae per day. They are effective against the thrips species commonly found in greenhouses and indoor potted plants. However, note that there are some, more unusual, tropical thrips species that are difficult to control, where neither beneficial insects nor chemicals have a good effect. They often come home with houseplants, are dark in color and sometimes have white stripes. One example is Echinothrips, which is particularly difficult to control. It is often an advantage to combine swirskii with <a href="https://shop.nyttodjur.se/shop/15-trips/16-oriusbaggar/" target="_blank">orius beetles</a> against adult thrips, and <a href="https://shop.nyttodjur.se/shop/11-vita-flygare---mjolloss/9-nyttodjur-mot-vita-flygare/" target="_blank">Encarsia</a> and <a href="https://shop.nyttodjur.se/shop/11-vita-flygare---mjolloss/10-gula-klisterskivor/" target="_blank">adhesive discs</a> against whiteflies.

Use 1 bag per plant or 2-3 bags/ m² . Over the next 4-6 weeks, the predatory mites will move out of the bag and onto the plant. The bag does not need to be opened or pierced, it already has small holes where the mites can come out. The predatory mites should be released immediately after receipt, but can be stored for a couple of days at 15 degrees. </div>
