Urea plant growth regulator with cytokinin activity. Mainly used as a defoliant for cotton, but also for defoliating apple trees, grape vines, hibiscus, kidney beans, soybeans, peanuts and other crops. It has obvious inhibitory effect, and the dosage is 0.3~3kg/hm2. For example, the cotton field dosage is 0.5kg/hm2Chemicalbook, and the medicine is used when 50%~60% cotton peach is opened, and the preparation is diluted into 500L/hm2 aqueous solution and sprayed on the plants, the effect of defoliation is 98%. It can also be used to control weeds such as barnyardgrass, dog tooth grass, crabgrass, crocodile grass, creeping wheatgrass, and scrofula. The dosage is 3kg/hm2, and the control effect is nearly 100%.
