It is an active acaricide produced from fermentation products of Streptomyces subspecies. It is highly active on various phytophagous mites that live on tea plants, pome fruits, stone fruits, citrus, watermelon, strawberry and egg plants. It is also an insecticide that is active against aphids, cutworms, leafrollers and thrips. It appears to stimulate the release of gamma-aminobutyric acid (GABA) which affects the chloride channels of the central nervous system."}]
