Product handling

Application

Hang sachets in sheltered locations in the crop, not exposed to direct sunlight
Sachets do not have an exit hole, so each sachet needs to be cut open or an exit hole needs to be pierced into it
Hold sachets by the cardboard strip at the top, to avoid damaging the predatory mites

In contrast to other Koppert products containing mites in sachets, Spidex Boost does not contain a rearing system which produces several generations of predatory mites over time. The mites will leave the sachets within a few days.

Dosage

The dosage of Spidex Boost depends on climate, crop and pest density and should always be adjusted to the particular situation. Start introduction preventively or as soon as the first spider mites are detected in the crop. Use at least 4,000 sachets per ha and hang them evenly spaced in the crop. Release should be repeated weekly if the pest is not controlled. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
