Problems solved by technology

[0002] According to P593 and P652 of "Encyclopedia of Fine Chemicals—Pesticide Volume", editor-in-chief: Zhou Xuemin, Zhejiang Science and Technology Press, 2000, December, ISBN7-5361-1517-5, it is introduced that promethazine belongs to the selective systemic absorption of triazines. Conductive pre-emergence herbicide, used to control annual broad-leaved weeds, the effect is remarkable, but the effect on grass weeds is poor, and it is easy to cause phytotoxicity when used with high activity. There are 40% and 50% wettable powder formulations: secbutyl Ling belongs to dinitroaniline pre-emergent herbicides. It is used for the control of grass weeds. It has a large dosage and poor activity. It has a 48% emulsifiable oil formulation
The main problem is that their respective weed control spectrums are different, and the cost of use is high
