| 摘 要： | 在温室条件下,研究了吡氟草胺与2甲4氯钠盐混用的除草活性,以及60%吡氟草胺·2甲4氯WP茎叶处理与土壤处理的效果差异.结果表明:吡氟草胺+2甲4氯钠盐150 g/hm2(单位下同)+300、150+450、150+600 3个配比效果较好,且土壤处理效果要略好于茎叶处理,但差异不明显.吡氟草胺对稗草等禾本科杂草特效,且对小麦安全,2甲4氯钠盐对苘麻等阔叶杂草特效,但对小麦安全性系数相对较低,因此,混用扩大杀草谱,在达到预期防效的前提下,应尽量降低2甲4氯钠盐的含量.

| Abstract: | Effect of diflufenican mixed with MCPA-Na on herbicidal activity as well as differences between foliar treatment and soil treatment were studied.Results showed that the best match effect of diflufenican MCPA-Na was 150 300,150 450,150 600 g/hm2.Effect of soil treatment was better than foliar treatment,but there was no significant difference.Diflufenican showed special effect on Echinochloa crus galli(L.) Beauv and other cereal weeds without injuring wheat.MCPA-Na had special effect on Abutilon theophrasti Medic.and other broadleaf weeds;but its safety coefficient on wheat was lower.Therefore,diflufenican mixed with MCPA-Na enlarged weed control spectrum.However,MCPA-Na content should be reduced on the premise of achieving desired weed control effect. |
