Agricultural Herbicides Selective absorption herbicides ametryn 80% WP
White crystalline solid. M.p.80 ~ 84 C (recrystallized in petroleum ether), density 1.19g/m3, vapor pressure 1.12 * 10-4Pa. The degree of contention is acetone 500g/L, methanol 450g/L, toluene 400g/L, water 18.5mg/L. It is stable in slightly acid or slightly alkaline medium, and is easy to hydrolyze in strong acid and strong alkali medium. It is not inflammable and corrosive.
Selective internal absorption herbicide. It is a typical inhibitor of photosynthesis. It is used for sugarcane, citrus, corn, soybeans, potatoes, peas and carrot fields to prevent annual weeds. High dose can prevent some perennial weeds and prevent weeds. 80% WP 1.95-3 kg/hm2 (effective ingredient 1.56-2.4 kg) was used in spring sugarcane field, and 600-750 kg water was sprayed on stem and leaf. For autumn sugarcane field, 80% WP was used for spraying 600-750 kg of water at 3-leaf stage of weeds with 1.05-1.95 kg/hm2 (active ingredient 0.84-1.56 kg). Other crops can be used for soil treatment after seeding or after seedling treatment. At low concentration, atrazine can promote plant growth, stimulate the growth of buds and roots, promote leaf area and stem thickening. But at high concentrations, it also has a strong inhibitory effect on plants.
