Nematodes against Colorado potato beetle larvae 20m²

Attention: this product is delivered directly from the supplier with a general manual about the use of nematodes. These nematodes can only be applied when the ambient temperature is at least 10°C (April/May) and for soil treatment after harvesting of the potatoes: How to use on the potato plant? The nematodes are dissolved in water and then sprayed over the potato foliage. Both the top and the underside of the leaf have to be well moistened. This treatment should be done in the evening since the nematodes are not resistant to UV radiation and the leaf has to remain wet for at least 6 hours. in the evening the humidity rises and the plants retain moisture longer. A leaf treatment with a conventional knapsack sprayer is possible but all filters smaller than 1 mm must be removed, otherwise the nematodes will be damaged. It is recommended to use a wetting agent (organic fatty acid such as an ecological detergent) so that the nematodes adhere better to the leaf. The treatment has to be repeated after 1 week. You can use the same packaging if it is kept in a closed jar in the refrigerator and the expiration date has not yet passed. The treatment can be carried out as soon as the larvae are present at an ambient temperature of 10°C. Serious damage? Treat the soil too! If you have had a lot of Colorado potato beetle infestation, it is best to treat the soil with nematodes after the potato harvest. The old larvae of the Colorado potato beetles drop from the leaves and crawl into the soil. At that moment it is best to control them with nematodes. By doing so you will avoid a new attack of Colorado potato beetles the next season or an infestation on the late potato varieties in the same season.
