It is a broad-spectrum herbicide with special effects on rice field, cow grass and valerian, which can effectively prevent ragweed, turfgrass, water dentate, small alkali grass, sedge, crabgrass, marmot, alfalfa, Look at annual weeds such as maiden and wild oats, and safe for rice, wheat, rape, peanuts, soybeans, cotton, corn, sugar cane and other crops.
The China Pesticide Network Xiaobian today introduces the whole process of the use of chlorpyrifos .
First, the role of chlorpyrifos killing grass is a selective herbicide for internal absorption, low toxicity to humans and animals. The medicinal agent is mainly absorbed by the weeds and roots of the weeds, and has no effect on the germination of the weed seeds. Only when the weed seeds are germinated, the absorbing agent acts. This product inhibits the biosynthesis process of α-amylase, so that the hydrolysis of starch in the germinating seeds is weakened or stopped, and the shoots are killed. The effect of the two-leaf stage before the two-leaf stage was significant, and the effect of the three-leaf stage was significantly reduced. The effect period was 25 to 30 days, and it changed with temperature and soil quality. The herbicide can move with water in the soil, and the general leaching depth is 122 cm.
Second, the control object and use technology of chlorpyrifos
It can prevent a variety of weeds such as Mai Niang, Matang, foxtail, yarrow, thousand gold, broken sedge, and sedge. It is suitable for weeding rice, vegetables, barley, rape, and milk vetch. The melon land is generally used in the pre-emergence seedlings, with 30,000 to 3,750 ml of 50% emulsifiable concentrate per hectare and 750 kg of water for soil spray treatment.
Third, the use of chlorpyrifos Note 1 The effect of chlorpyrifos on the sedge of the three-leaf stage is reduced, should be mastered before the use of sedge two leaves. 2 can not be mixed with 2,4-drip, otherwise it will reduce the herbicidal effect of the herbicide.
" The whole process of the use of chlorpyrifos ", the pesticide network Xiaobian is summarized here, want to know more pesticide information, please log on to the China Pesticide Network to view!
