Overview
Glyphosate aqueous solution is a liquid formulation of the herbicide glyphosate, typically containing 30-50% active ingredient. It is one of the most widely used agricultural chemicals globally, valued for its effectiveness against a broad spectrum of weeds. The solution is commonly prepared as an isopropylamine salt for improved solubility and handling. Since its introduction in the 1970s, glyphosate has become fundamental in modern agriculture, particularly with glyphosate-resistant crops.
Physical and Chemical Properties
The aqueous solution appears as a clear to slightly colored liquid with a mild characteristic odor. It has good chemical stability under normal storage conditions but may degrade when exposed to extreme temperatures or sunlight over prolonged periods. Glyphosate works by inhibiting the EPSP synthase enzyme, disrupting the shikimic acid pathway in plants. This systemic action means it's absorbed through foliage and transported throughout the plant, making it effective against perennial weeds with extensive root systems.
Main Applications
Primary use is in agriculture for pre-planting and pre-harvest weed control in crops like soybeans, corn, and cotton. It's also used in orchards, vineyards, and non-crop areas such as roadsides and industrial sites. In forestry, glyphosate solutions help manage competing vegetation in tree plantations. The concentration and application rates vary significantly depending on target weeds and environmental conditions, typically ranging from 1-5 liters per hectare.
Safety and Storage
While glyphosate has low acute toxicity to mammals, proper handling is essential. Use gloves, protective clothing, and eye protection during mixing and application. Avoid inhalation of spray mist. Store in original containers between 5-30°C, away from food and feed. The solution is corrosive to some metals, so storage tanks should be made of stainless steel or plastic. Shelf life is typically 2 years when stored properly.
B2B Procurement Guide
When purchasing glyphosate aqueous solution commercially, verify the concentration (commonly 360g/L or 480g/L). Check for proper labeling including batch number, production date, and expiry date. Consider transportation regulations - some regions classify it as hazardous goods. Bulk purchases (1000L IBC containers) offer better pricing but require proper storage facilities. Always request Material Safety Data Sheets (MSDS) and certificate of analysis.
