Usage

General Description

3,6-dichloropicolinonitrile is a chemical compound with the formula C6H2Cl2N2. It is a white crystalline solid that is commonly used as an herbicide in the agricultural industry. It functions by inhibiting the enzyme acetohydroxyacid synthase, which is essential for branched-chain amino acid production in plants. This disrupts the plant's ability to grow and ultimately results in its death. Due to its herbicidal properties, 3,6-dichloropicolinonitrile is often used to control weeds in crops such as corn, soybeans, and cotton. However, it is important to use this chemical with caution, as it can have harmful effects on both humans and the environment.
