GRANDEX is another quality insect virus product from the Andermatt Biocontrol, Switzerland stable. GRANDEX is based on Cydia pomonella granulovirus. GRANDEX is highly selective, only targeting Codling and Oriental Fruit Moth making it very compatible with IPM systems. With the introduction of Mastrus parasitoid for Codling moth and Heringia calcarata for Woolly aphid, the use of very selective insecticides like GRANDEX is paramount to the successful integration of these two key biological control agents. GRANDEX is a very popular biological insecticide in Europe, New Zeland and North America where the use of Mating Distruption in combination with virus sprays is well advanced.
