籽粒苋出苗后茎叶处理 ,防除禾本科杂草以 10 .5 %高效盖草能EC 75 0ml/hm2 、5 %精禾草克EC 75 0ml/hm2 、15 %精稳杀得EC 75 0ml/hm2 、5 %精喹禾灵EC 75 0ml/hm2 效果较好 ,防除阔叶草、莎草以 2 5 %灭草松AS 6 0 0 0ml/hm2 为宜。播前用 48%氟乐灵EC 15 0 0ml/hm2 作土壤处理 ,对禾本科杂草的防效达 90 %以上 ,对阔叶杂草的株防效达 70 %。 6 0 %丁草胺EC 15 0 0ml/hm2 、5 0 %乙草胺EC 12 0 0ml/hm2 、5 6 % 2甲 4氯钠D等对籽粒苋有药害 。
It was effective to control cereal weeds with 10.5% haloxyfop-R-methyl, 5% NC-302D(+),15% fluazifop-p-butyl or 5% quizalofop-p-ethyl and coco-grass and broad-leaf weed with 25% bentazone after seeds germinated. When dealt before sowing, 48% trifluralin could be used to control both cereal weeds and broad-leaf weeds and the controlling efficiency was 90% respectively and 70%. The results also showed that 60% butachlor, 50% acetochlor and 56% MCPA-Na were dangerous to three-coloured amaranth.
