Closed weeds in paddy fields Due to continuous use of pyrazosulfuron-methyl, bensulfuron-methyl and other agents for many years, wild boi cuspidum (Ascus edodes), Alisma orientalis (water cabbage), Yujiu (broccoli), and Sabah et al. The sedge weeds such as weeds and weeds have increased resistance to the disease and have become more harmful.
The new drug, pyrimidine sulfonazosulfuron, can replace the pyrazosulfuron-methyl and bensulfuron-methyl that have been used for more than 20 years to control broad-leaved weeds and sedge weeds in rice fields and make the weeds on pyrazosulfuron-methyl. The problem of resistance to bensulfuron was alleviated.
Clearing and acetochlor can be combined to ensure the normal development of rice roots while ensuring the weeding effect, so that seedlings take root early, return to green as early as possible, early deliveries, and mature earlier, and there is a clear increase in yield compared with the commonly used combination on the market. After 3 to 5 days after rice transplanting, in the first leaf stage of barnyardgrass, 50% per acre is used to remove 9 grams of 50% of pretilachlor 60-70 ml, and the first line of clear water dispersible granules is dissolved in a small amount of water. Protopine mixed, and then evenly mixed with soil or spread fertilizer applicator.
The line was mixed with butachlor: 5 to 7 days after rice transplanting, 1.5 times per acre of barnyardgrass was used to clean 9 grams per acre with 60% butachlor (Machette, Rhodia) 100 ~ 150 ml or 90% butachlor 70 ~ 90 ml, using the method of the line with the mixed blanched amine.
