Koromite™ is a new selective acaricide for mite control in cotton. The active ingredient milbemectin is a mixture of natural compounds derived from the soil microorganism Streptomyces hygroscopicus subsp. aureolacrimosus. Milbemectin is highly effective against a wide range of pest mite species including the strawberry spider mite (Tetranychus turkestani), two- spotted spider mite (T. urticae), and pacific spider mite (T. pacificus) in cotton. Milbemectin acts through both contact and ingestion. It is active on all life stages of mites including eggs and at sub lethal levels significantly reduces the egg-laying capacity of treated adult females. Milbemectin has a good toxicological and environmental profile and has recently been classified by the US-EPA as a reduced risk compound. Milbemectin has excellent crop safety, minimal impact on beneficial arthropods and is not cross-resistant to existing acaricides thus making it an excellent choice for use in integrated pest management and resistance management programs.
