采用室内盆栽喷雾法和田间茎叶喷雾法,研究草甘膦的复配应用技术。室内测试结果表明:草甘膦与麦草畏配比为(0.5~512)∶1对旱稗和空心莲子草均表现为相加作用;草甘膦与2甲4氯配比为(2.85~5.24)∶1对旱稗和藜均表现为相加作用;草甘膦与草铵膦配比为(0.90~10.32)∶1对旱稗表现为相加作用,对藜表现为增效作用。田间药效结果表明:药后30 d,35%麦草·草甘膦水剂在1200~1500 g/hm2剂量下,总草株防效和鲜质量防效分别为93.16%~97.96%和95.24%~99.42%;36%2甲·草甘膦水剂在1296~2592 g/hm2剂量下,对总草株防效和鲜质量防效分别为91.09%~94.77%和90.04%~95.07%;36%草甘膦·草铵膦水剂在1404~2808 g/hm2剂量下,总草株防效和鲜质量防效分别为92.30%~97.66%和93.08%~97.65%。3个复配剂均能有效防除非耕地杂草,持效期达30 d 以上。草甘膦与除草剂复配具有较好的配伍性,与麦草畏、2甲4氯或草铵膦复配均表现为相加或增效作用,室内复配筛选结果与田间药效结果一致。3个复配剂与单剂相比,既增加了药效又提高了速效性。
採用室內盆栽噴霧法和田間莖葉噴霧法,研究草甘膦的複配應用技術。室內測試結果錶明:草甘膦與麥草畏配比為(0.5~512)∶1對旱稗和空心蓮子草均錶現為相加作用;草甘膦與2甲4氯配比為(2.85~5.24)∶1對旱稗和藜均錶現為相加作用;草甘膦與草銨膦配比為(0.90~10.32)∶1對旱稗錶現為相加作用,對藜錶現為增效作用。田間藥效結果錶明:藥後30 d,35%麥草·草甘膦水劑在1200~1500 g/hm2劑量下,總草株防效和鮮質量防效分彆為93.16%~97.96%和95.24%~99.42%;36%2甲·草甘膦水劑在1296~2592 g/hm2劑量下,對總草株防效和鮮質量防效分彆為91.09%~94.77%和90.04%~95.07%;36%草甘膦·草銨膦水劑在1404~2808 g/hm2劑量下,總草株防效和鮮質量防效分彆為92.30%~97.66%和93.08%~97.65%。3箇複配劑均能有效防除非耕地雜草,持效期達30 d 以上。草甘膦與除草劑複配具有較好的配伍性,與麥草畏、2甲4氯或草銨膦複配均錶現為相加或增效作用,室內複配篩選結果與田間藥效結果一緻。3箇複配劑與單劑相比,既增加瞭藥效又提高瞭速效性。

To provide efficacy information for product development,the ratio of glyphosate mixtures with other chemicals was studied in pot and field spraying tests.Additive effects were observed at glyphosate:dicamba rations of (0.5 ~512)∶1 on Echinochloa crusgalli and Alternanthera philoxeroides,Additive effects were also found at glyphosate:2 -methyl -4 -chlorine at ratios of (2.85 ~5.24)∶1 on E.crusgalli and quinoa,and for glyphosate:glufosinate at ratios of (0.9 ~10.32)∶1 on E.crusgalli with a synergistic effect on quinoa.In field trials dicamba -glyphosate 35%AS at 1 200 ~1 500 g/hm2 provided 93% ~98% and 95% ~99% control of grass weeds based on visual assessment and fresh weight, respectively,at 30 days after spraying.Similarly,2 methyl 4 chlorine -glyphosate 36% AS at 1 296 ~2 592 g/hm2 achieved 91% ~95% and 90% ~95% grass control and glyphosate -glufosinate 36%AS at 1 404 ~2 808 g/hm2 con-trolled grasses at 92% ~98% and 93% ~98%,also based on visual evaluations and fresh weight,respectively.The three glyphosate containing formulations effectively controled non -arable weeds for more than 30 days.Glyphosate was com-patible with the other herbicides tested:dicamba,2 methyl 4 chlorine and glufosinate.These three two -way combination had additive or synergistic effects on non -cultivated land weeds.Pot testing results were consistent with the field efficacy,and the mixtures were not only more ef-fective but also had quicker activity than the single her-bicide.
