| 摘 要： | 以水杨醛、3,4-二氯苯胺和4,6-二甲氧基-2-甲砜基嘧啶为原料合成了新型除草剂ZJ0862 ,其结构经1H NMR、MS、IR和元素分析确证。室内生物测定试验表明,ZJ0862在有效成分60 g/hm2剂量下,对水田重要杂草稗草和异型莎草的抑制率达90%以上;在45 g/hm2剂量下,对看麦娘、野燕麦、狗尾草等15种田间常规杂草的抑制率达85%~100%,杀草谱较广;田间试验结果显示,ZJ0862在150 g/hm2剂量下对移栽水稻安全,且在 60~90 g/hm2剂量下对水田主要杂草水苋菜、陌上菜、异型莎草等的防效达81.3%~98.4%。毒理学评价结果显示,该药剂为低毒、无刺激、弱致敏和致突变阴性。ZJ0862具有高效、低毒、安全的特点,在移栽水田将具有较好的开发前景。

| Abstract: | A novel herbicidal compound ZJ0862 was synthesized from salieylic aldehyde,3,4-dichloro-aniline and 4,6-dimethoxy-2-methyl sulfonyl pyrimidine.The chemical structure of the compound was confirmed by 1H NMR,MS,IR and elemental analysis.The bioassay indicated that ZJ0862 had good herbicidal activity to the important weeds in rice field,such as Echinochloa crus-galli and Cyperus difformis(inhibition rate >90%).And the inhihition rate for 15 common weeds such as Alopecurus aequalis,Avena fatua,Setaria viridis were 85%~100% at 45 g/hm2.It had broad spectrum weed control.The field trial showed that the compound(150 g/hm2) was safe to transplanted rice,and had good efficacy(81.3%~98.4%) to the mainly weeds in paddy,such as A.baccefera and L.procumbens,under the concentration of 60~90 g/hm2.Toxicological tests showed it was low toxicity,non irritating,slightly sensitisation and negative mutagenicity.ZJ0862 had good potential to dovelop in transplanted rice. |
