The spotted wing drosophila is a vinegar fly (drosophila suzukii) originating from South-East Asia attacking almost ripe fruit. It mainly attacks red and soft summer fruit or fruit with reddish tones, such as strawberries, cherries, blueberries, raspberries, blackberries, plums, peaches, nectarines, apricots, grapes, etc. The gluttonous larvas can end up in harvest failure.
Control of spotted wing Drosophila can be done by direct or indirect measures. When using plant protection products, the generally strict application regulations must be followed. In particular, attention should be paid to the use of nozzles with the highest possible drift reduction. Especially for viticulture, a new application method with the ITR nozzle has been developed, which minimizes drift in viticulture. This allows the use of special insecticides against the spotted wing Drosophila with maximum protection of predators.
Lechler ITR nozzle – Perfect for spotted wing drosophila control
The ITR nozzle 80-01 C is an air injector hollow cone nozzle that produces a coarse to extremely coarse droplet spectrum with extreme high drift reduction of 95%. JKI registration in the list of loss reducing techniques for application in vineyards exists. This allows growers to apply insecticides in grape zones in viticulture through a simple nozzle change while maintaining the 95% drift reduction class. Depending on the height of the grape zone 2 or 3 nozzle per side are needed. Through the use of ITR nozzles a sharp demarcation towards the leaf wall can be reached for best protection of predatory mites.
