1992年,我们用增效对硫磷防治核桃举肢蛾(Atriglans hetaohei),通过室内药效测定和田间试验,初步确定了该药对举肢蛾幼虫的致死中浓度 L_(C50)=986.5μg/g;田间防治采用600倍液,喷药72小时后举肢蛾死亡率较用甲基对硫磷高;防治区核桃好果率达90%以上,保产效果62.97%～73.73%。1 供试药剂试验药剂为50%增效对硫磷乳油(武功农药厂),对照药剂有50%甲基对硫磷乳油
In 1992, we used synergistic parathion to control Atriglans hetaohei and determined its lethal concentration to Cydia moth larvae through indoor pharmacodynamic test and field experiment. The concentration of L50 is 986.5μg / g; field control with 600 times the liquid, after spraying 72 hours after the mortality of Metalagosis moth more high than methyl parathion; control walnut good fruit rate of 90%, yield-effective 62.97% ~ 73.73%. 1 for the test drug test agent 50% synergistic parathion EC (Wugong Pesticide Factory), the control agent 50% methyl parathion EC
