The dosage of Spidend depends on climate, crop and spider mite density and should always be adjusted to the particular situation. Start introduction as soon as the first spider mites are detected in the crop. Introduction rates typically range from 0.25-25 per m2/release. Releases should be repeated at least 3 times at weekly intervals, or until the pest is controlled. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
