Madex XLV is a biological insecticide containing the insecticidal virus Cydia pomonella granulovirus isolate GV-0017 (0.06%). It is specifically designed for organic production to control the larvae of the Codling Moth and the Oriental Fruit Moth. The product works by being ingested by the larvae, where the viral occlusion bodies (OBs) dissolve and release infectious virions that replicate within the insect, eventually causing death. It is used as a spray on fruit and foliage of trees, including apple, pear, quince, apricot, peach, plum, cherry, nectarine, and various nut trees. For effective control, thorough spray coverage of target foliage and fruit is essential. The product is fast-acting once ingested, though mortality occurs a few days after ingestion. When handling, avoid contact with eyes and skin; if contact occurs, rinse thoroughly with water. Use appropriate personal protective equipment, including long-sleeved shirts, long pants, waterproof gloves, shoes plus socks, and protective eyewear. Note that the product breaks down under direct sunlight, so timing and coverage are critical for efficacy.
