摘　　要：应用新型植物源生物杀虫剂GF-120,在脐橙和温州蜜柑上进行了防治橘小实蝇的使用浓度和施药方式试验。结果表明,GF-120600倍液和450倍液防治橘小实蝇的效果显著,与50%倍硫磷乳油1500倍液无显著差异,且未见有药害现象,是防治橘小实蝇的理想药剂;点喷法与挂瓶法的防治效果相当。本着简便易行和节约成本的原则,在田间推荐使用GF-120600倍液进行隔株点喷,点喷部位在树冠中下层叶片背面。Through bioassay in the laboratory and control test in the field,the control efficacy of GF-120,which was used in two ways：spraying and dropping in a bottle,and field trial with common pesticide was compared in the paper.The results showed that there was no significant difference in control efficacy between GF-120 RB diluted 600 times as well as 450 times and 50% fenthion EC diluted 1 500 times with water.As well as the control efficacy of plots sprayed GF-120 was indifferent from dropping in a bottle.GF-120 was an ideal pestitcide because of non-staining,convenient to use.But when taking the cost into account,the author considered that GF-120 diluted 600 times with water was applied to the back of leaves in the crown of the middle and lower with spraying on the precondition of ensuring control efficacy.
