| 摘要: |
| 室内将莠灭净和2甲4氯异辛酯原药按1.0:10.0;1.1:6.0;1.5:6.0;1.7:6.0;2.0:6.0配成混剂,进行混剂各配比对马唐[Digitaria sanguinalis(L.) Scop]、牛繁缕[Malachium aquaticum(L.) Fries]幼苗活性试验和马唐、胜红蓟(Ageratum conyzoides L.)发芽率的影响试验。结果表明,莠灭净与2甲4氯异辛酯以质量比1.5:6.0混配的协同增效作用最明显,此配比对马唐和牛繁缕的共毒系数(CTC)分别达到137.1和279.3,对马唐和胜红蓟的发芽抑制率分别为98.3%和96.7%,对马唐的防治效果亦达81.3%。 |

| Abstract: |
| The Ametryn,MCPA isooctyl and their mixtures in the ratios of 1.0:10.0;1.1:6.0;1.5:6.0;1.7:6.0;2.0:6.0 were produced in lab. The toxicity trial on the seedlings of Digitaria sanguinalis Scop and Malachium aquaticum Fries and the effect trial on the seed germination of D.sanguinalis Scop and Ageratum conyzoid were conducted. As can be seen.The mixture of 1.5:6.0 has the best synergistic effect in the toxicity trail,with CTC of 137.1 and 279.3 to D.sanguinalis Scop and M.aquaticum Fries respectively. The inhibition to the seed germination of D. sanguinalis Scop and A. conyzoides are 98.3% and 96.7% respectively. The control effect of this ratio on D. sanguinalis Scop is 81.3%. |
