Overview
Clethodim is a selective post-emergence herbicide widely used in agriculture to control grassy weeds in broadleaf crops. It belongs to the cyclohexanedione oxime family and is known for its effectiveness against annual and perennial grasses. Clethodim works by inhibiting acetyl-CoA carboxylase (ACCase), an enzyme essential for fatty acid synthesis in plants. This mode of action makes it highly effective against grassy weeds while being safe for most broadleaf crops.
Physical and Chemical Properties
Clethodim is a pale yellow to brown oily liquid with a molecular weight of 359.91 g/mol. It has a density of 1.14 g/cm³ and is soluble in most organic solvents but only slightly soluble in water. The chemical stability of clethodim is influenced by environmental factors such as temperature and pH. It degrades under strong alkaline or acidic conditions, which is an important consideration for storage and application.
Main Applications
Clethodim is primarily used in crops such as soybeans, cotton, sunflowers, and peanuts to control grassy weeds. It is applied post-emergence, meaning it targets weeds after they have sprouted. In addition to agricultural uses, clethodim is sometimes employed in non-crop areas like roadsides and industrial sites to manage unwanted grass growth. Its selectivity makes it a preferred choice for integrated weed management systems.
Safety and Storage
Clethodim should be handled with care, using appropriate personal protective equipment (PPE) such as gloves, goggles, and protective clothing. Avoid inhalation or direct contact with skin and eyes. Storage conditions are critical for maintaining clethodim's efficacy. It should be kept in a cool, dry place away from direct sunlight and extreme temperatures. Containers must be tightly sealed to prevent contamination and degradation.
B2B Procurement Guide
When procuring clethodim in bulk, it is essential to verify the CAS number (99129-21-2) and the purity of the product. Reputable suppliers should provide certificates of analysis (CoA) and material safety data sheets (MSDS). Price ranges vary depending on purity, volume, and supplier. For reference, clethodim typically costs between $50 and $100 per liter. Always consider logistics and storage requirements when planning large-scale purchases.
