  • Applications

    Pirimicarb (CAS 23103-98-2) is a carbamate insecticide used primarily in agriculture to control aphids on fruit trees, vegetables, and other crops, in both field and greenhouse production. Typical applications include foliar sprays to protect crops during the growing season, often integrated into pest management programs (IPM) and commercial crop protection programs. It is formulated in several foliar formulations suitable for crop protection and is considered a component of aphid management strategies in horticulture and field crops, subject to local regulations and formulation limits.
