Alachlor is an herbicide from the chloroacetanilide family. It is an odorless, white solid. The greatest use of alachlor is for control of annual grasses and broadleaf weeds in crops. Use of alachlor is illegal in the European Union [1] and no products containing alachlor are currently registered in the United States. [2]

Alachlor was first registered in 1969 as a selective herbicide for control of broadleaf weeds and grasses. Alachlor is produced by the Monsanto Company in the US. A Registration Standard was issued for alachlor on November 20, 1984. The Registration Standard involved a thorough review of the scientific data

Alachlor as Lasso in field-use rate (11 micrograms/cm2) and undiluted (217 and 300 micrograms/cm2) proportions were left on rhesus monkey skin for 12 h and decontaminated with soap and water (10% Ivory liquid v/v with water). Continual successive washes (6-8 in sequence) recovered 80-90% of the skin-applied alachlor.

Alachlor is the second most widely used herbicide in the United States, with particularly heavy use on corn and soybeans in Illinois, Indiana, Iowa, Minnesota, Nebraska, Ohio, and Wisconsin. Release Patterns . The major source of environmental release of alachlor is through its manufacture and use as a herbicide.

Alachlor: EPA registers pesticides under Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). In addition, EPA periodically reevaluates pesticides to ensure their safety in light of new scientific and regulatory information. In this section you will find the primary documents produced to support the registration and review processes.

Absorption & Translocation: Absorbed primarily by emerging plant shoots (grass coleoptile, broadleaf hypocotyl or epicotyl, and secondarily by seedling roots;older plants readily absorb alachlor into roots and translocate upward throughout shoots; translocation in established plants irrelevant as alachlor is phytotoxic only to emerging seedlings.
