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 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.
