Garden borer larvae, Phyllopertha horticola , can cause significant damage to lawns. However, they can be controlled with the help of nematodes, microscopic roundworms, which are watered over the lawn surface. They are sold in packages of 50 million or 250 million nematodes, which is enough to treat 50-100 m² or 300-500 m² of area respectively.
The adult garden borers are usually seen during May-June, and only for a short period, when they lay their eggs in the grass. Characteristic of the garden borer is that it flies low over the grass, on sunny mornings. The eggs that are laid begin to hatch from June onwards. It is the larvae that do the damage to the lawn, as they eat the roots of the grass. They grow during the season and overwinter in the soil. The following spring they pupate into a new generation of adult garden borers.
The garden borer larvae feed on the roots of the grass near the surface. The grass becomes dry and yellowish and may begin to loosen from the soil surface. The larvae also attract birds and other animals, which can also destroy the lawn as they root around in the grass to find food.
When the nematodes are watered into the soil, they actively search for a suitable host in the form of a garden borer larva. They penetrate it and infect it. Bacteria from the nematodes kill the larva. The nematodes multiply inside the infected larva, and then leave it to search for new larvae.
Treatment times
The optimal time for treatment is from late July to mid-September . During this period, the larvae are small and close to the surface at the grass roots. Treat approximately 4 weeks after observation of the adult insects , to catch the first larvae when the eggs hatch.
Nematodes can primarily control the small, newly hatched larval stages of garden borers. Since nematodes also depend on soil heat to work, they are most effective for a shorter period during the summer and early fall.
User manual
The contents of the bag are dissolved in water while stirring, and then watered over the surface. Use the solution with the nematodes immediately after mixing.
Use the nematodes only during the appropriate treatment period to achieve an effective result. The treatment is mainly effective against the smaller larval stages of the garden borer. Optimal soil temperature is above 12 degrees for four weeks after treatment to ensure that the nematodes are active . At lower temperatures, or larger larval stages, a reduced effect can be expected.
As the nematodes live in the water film between the soil particles, it is important that the soil is kept moist during treatment. If the treatment surface is dry, it is watered preventively before treatment. Also water after treatment to thoroughly rinse the nematodes into the soil. The surface should then be kept moist for at least two weeks after treatment.
Treatment should not be carried out during heavy rain as there is a risk of washing away the nematodes.
The nematodes should be watered out early in the morning, in the evening or on a cloudy day, as they are sensitive to UV light.
