Grandevo WDG is a biological insect and mite control for mites, aphids, thrips, and more, labeled for edible crops and ornamental plants in fields and greenhouses. It contains dead cells of Chromobacterium subtsugae strain PRAA4-1T and spent fermentation media. Grandevo is best used on newly hatched larvae and nymphs and when populations are low. Grandevo has multiple modes of action: repel, stop feeding (stomach poison), reduce reproduction and induce mortality to prevent the development of damaging populations of sucking and chewing insects, flies and mites. It is slow working, requiring 2-3 sprays in 7 day period before population decline can be seen. With high pest populations, use a knockdown spray, or use a higher rate, shorter spray interval, or increase spray volume. A spray adjuvant is recommended to assure complete coverage on hard-to-wet crops.
