Prometryn offers targeted weed control without harming your crops. It is absorbed through roots and foliage and transported throughout the weed, leading to effective suppression of unwanted plant growth.
Controls annual weeds such as:
Barnyardgrass, wild amaranth, purslane
Pigweed, foxtail, goosegrass
Polygonum, quinoa, and horseradish
Trusted across multiple broadleaf crops:
Field Crops: Peanut, soybean, cotton, wheat, rice, sugarcane, ramie
Perennial Crops: Tea plantations, fruit orchards
Nurseries and ornamentals
Effective both before and after weed emergence, allowing for integration into your weed management program at various crop stages.
Prometryn belongs to the triazine herbicide family and works by inhibiting photosynthesis in susceptible plants. Once absorbed through roots or leaves, it interferes with photosystem II, which halts energy production in weed cells, causing gradual death. The herbicide is most effective when applied pre-emergence, though it also shows activity on young, early-stage weeds.
1. When weeding rice seedling fields and Honda fields, it should be used when the seedlings turn green after rice transplanting or when the leaf color of eye cabbage (tooth grass) changes from red to green.
2. Weeding in wheat fields should be carried out at the 2-3 leaf stage of wheat and at the budding stage or 1-2 leaf stage of weeds.
3. Weeding of peanut, soybean, sugarcane, cotton and ramie fields should be used after sowing (planting).
4. Weeding in nurseries, orchards and tea gardens should be used in the sprouting period of weeds or after intertillage.
