Do you get spider mites regularly in your crop? If so, then spider mite prevention may be beneficial to you and your crop. Amblyseius andersoni is a predatory mite used in bio-control to prevent and/or slow the progression of spider mites in many plant species. It is added once flowers appear in the crop and can survive on pollen if no spider mite is present. Amblyseius andersoni is used in conjunction with Persimilis and the two species do not negatively interact. Andersoni is available loose in tubes of 10000 and 25000.
