摘  要:
将百草枯水剂分别与植物生长调节剂赤霉素、α-萘乙酸、3-吲哚乙酸进行复配,测定3种复配制剂的毒力及田间小区试验药效。结果表明,3种复配制剂的毒力分别是原药剂的5.0、1.5、3.4倍,田间小区试验50 mg.L-1+生长调节剂1 000 mg·L-1百草枯水剂,药后7 d均能达到2 000 mg·L-1百草枯的防治效果,并能延迟杂草返青时间2周左右。

摘  要:
Paraquat was mixed with gibberellin,α-naphthaleneacetic acid and 3-indleancetic acid respectively.The toxicities of the mixtures to duckweed were tested and herbicide effect in the field was examined.The result showed that the toxicities of the mixtures to the duckweed were increased to 5.0,1.5 and 3.5 times respectively,and the mixtures containing 1 000 mg·L-1 paraquat and 50 mg·L-1 regulator had close effect to the solution containing 2 000 mg·L-1 paraquat in the field after 7 days,and the weeds resurging time was delayed about 2 weeks in the treated fields with mixtures than the check fields treated with paraquat only.
