1. Low toxicity, contact herbicide. It exerts its herbicidal activity in the presence of light. It has the best effect before and early post-emergence. It has a wide weed-killing spectrum for weeds that germinate from seeds. It can control broad-leaved weeds, sedges and barnyard grasses, but has an inhibitory effect on perennial weeds. Control object: It can prevent monocot and broadleaf weeds in transplanted rice, soybean, corn, cotton, peanut, sugar cane, vineyard, orchard, vegetable field and forest nursery.
2. This product is a kind of fluorinated diphenyl ether. It is an ultra-low dosage selective, pre-emergence and post-emergent contact herbicide. Weeds are mainly killed by the absorption of the coleoptile and mesocotyl. Suitable for rice, soybean, wheat, cotton, corn, oil palm, vegetables and orchards, etc., to prevent and control broad-leaved weeds and certain gramineous weeds, such as dayflower, barnyard grass, sedge, sebony, brome, etc. Mandala, etc., the dosage is 1～2g active ingredient/100m2. For example, 4-6 days after rice transplantation, barnyardgrass bud stage to 1.5 leaf stage, use 24% EC 1.5-2.3mL/100m2 to make poisonous soil and spread evenly. It can also be sprayed with 0.5% granules. For soybean, cotton and other crops before seedling after sowing, use 24% EC 7.5mL/100m2 to spray water evenly on the soil surface.
