问:我家有几十亩直播水稻,没有打封闭草药,我想到水稻2叶1心期每亩用10%氰氟草酯200毫升、50%二氯喹啉酸50克、10%苄嘧磺隆40克除草,这样行吗?如果田间杂草发生量不大,杂草种类较少,有把握用短信中所说的几种药将草除掉,可以采用这种方法,否则最好采用土壤封闭 Q: There are dozens of acres of direct seeding rice in my house and there is no closed herb. I think of rice 2 leaf 1 heart per acre with 10% Cyhalofop ester 200 ml, 50% quinclorac 50 g, 10% bensulfuron 40 grams of weeding, so OK? If weeds in the field is not large, less weed species, it is safe to use the message said several drugs to get rid of grass, you can use this method, or the best soil Closed
