Rifit 50 EC Herbicide is a selective, pre-emergence broad-spectrum herbicide containing Pretilachlor 50% EC as an active ingredient. It is used in transplanted rice fields to control annual grasses, sedges and broad leaf weeds during the early crop stage. It helps to controls weeds that compete with rice plants for nutrients, water, and sunlight.
The herbicide works through the soil and is absorbed by germinating weed seedlings through roots and shoots and helps in better crop establishment and healthy growth.
Pretilachlor 50% EC
Mode of Entry: Root and shoot absorption
Time of Application: Pre-emergence
Mode of Action: Pretilachlor works by interfering with protein and lipid synthesis in germinating weed seedlings. The herbicide is absorbed through roots and shoots of emerging weeds and prevents proper cell growth and development. As a result, weeds fail to establish properly and gradually die before competing with the rice crop.
