室内生测结果表明:浙江基地合成的新的除草活性化合物ZJ0166在40~150g/hm2剂量范围内对大多数禾本科杂草、阔叶杂草以及莎草具有较高的除草活性,且对油菜、棉花安全.高粱为ZJ0166的敏感靶标,高粱水培法测得ZJ0166的ED50值为0.17mg/L,播前土壤处理法测得ZJ0166的ED502.39g/a.吸收传导性研究结果表明:ZJ0166由根、芽、茎叶吸收并在植物体内双向传导,以根吸收为主.田间试验结果表明:ZJ0166在15~45g/hm2剂量下对油菜、小麦田恶性杂草看麦娘具有很好的防效,对阔叶杂草牛繁缕、雀舌草等具有一定的防治效果,且对油菜各种生长发育性状无不良影响,增产效果明显;45g/hm2剂量下对小麦具有明显的药害.
The indoor bioassay results showed that the new herbicidal compound ZJ0166 synthesized in Zhejiang base had higher herbicidal activities against most grass weeds, broadleaf weeds and sedge in the dosage of 40-150g / hm2, , Cotton safety. Sorghum is a sensitive target of ZJ0166, the ED50 value of ZJ0166 was 0.17mg / L measured by sorghum hydroponics, the ED502.39g / a of ZJ0166 was measured by pre-sowing soil treatment.The results of absorption conductivity showed that: ZJ0166 was absorbed by roots, buds, stems and leaves and was bi-directionally transmitted in the plant to root absorption.The field experiments showed that ZJ0166 had a good effect on the weeds in wheat and rapeseed under 15 ~ 45g / hm2 Of the control effect on the broadleaf weeds Niuwatiwa, Quexiao grass has some control effect, and no adverse effects on the growth and development traits of rape, yield increase effect is obvious; 45g / hm2 dose of wheat has obvious medicine harm.
