2,4-Dichlorophenoxyacetic acid is a classic systemic herbicide and plant growth regulator widely used in agriculture. It can effectively eliminate broad-leaved weeds in wheat, rice, corn and sugarcane fields with low usage cost and obvious weeding effect. At proper concentration, it can promote plant cell division, accelerate fruit setting, prevent flower and fruit dropping, and is applied in fruit trees and vegetable planting management. It is also the core raw material for synthesizing various herbicide derivatives and pesticide compound formulations. In addition, it is used as chemical analytical reagent and organic synthesis intermediate in fine chemical industry. With stable herbicidal activity and mature application technology, it occupies an important position in modern agricultural pesticide field.

This substance is toxic and irritant with certain agricultural chemical hazard. Inhalation of dust will cause severe irritation to respiratory tract, leading to cough, chest pain and dizziness, long-term inhalation may damage nervous system, so wear professional protective mask and keep full ventilation during operation.
