摘要

摘要: 采用不同药剂处理黄瓜根结线虫病以筛选高效低毒低残留药剂,研究结果表明:全生育期1次用药,不同药剂处理下,黄瓜病情指数表现不同,其中对照病指最高,为66.67;其次为藜芦碱及辛硫磷病指分别为46.67和40;印楝素,印楝素+辛硫磷,藜芦碱+辛硫磷,病情指数较低,防效显著;以印楝素+辛硫磷防效最高,为54%,差异显著性分析显示印楝素与辛硫磷减半混配表现出一定的增效作用,防效分别高于单用印楝素、辛硫磷,且在P0.05水平上显著;在产量表现方面,所有药剂处理下均表现出一定的增产水平,即使是防效较差的藜芦碱其增产率也达19.98%。

Abstract: Using different pesticides,effect of controlling the cucumber root-knot nematodes was studied.The efficacy and residue toxicity of the pesticides were evaluated.The results showed that,when only one single application was applied during the cucumber growth period,(a) the control had a disease index of up to 66.67,while veratridine and phoxim had 46.67 and 40,respectively;(b) for azadirachtin,azadirachtin+phoxim or veratridine+phoxim,the disease index was low,but the preventive performance was good;(c) for azadirachtin+phoxim,the maximum preventive effect was 54%,and a significant synergy existed(at P0.05 level);and,(d) all pesticides tested showed varying degrees of improvements on productivity,even the least effective one,veratridine,increased cucumber yield by 19.98%.
