稻纵卷叶螟田间药效试验结果及分析(毕业论文5100字)

摘  要： 研究10%氟虫双酰胺.阿维菌素SC对稻纵卷叶螟的毒力及防效。经新复极差检验，每10%氟虫双酰胺.阿维菌素SC 450ml以上，对稻纵卷叶螟的防治效果与每公顷用20%氯虫苯甲酰胺150ml的效果无极显著性差异，且持效期长达20天。而且每公顷用10%氟虫双酰胺.阿维菌素450ml，对高龄稻纵卷叶螟同样具有良好的防治效果。10%氟虫双酰胺.阿维菌素商品名稻腾（6．7％氟虫双酰胺+3．3％阿维菌素）拜耳作物科学公司提供.有防效高、杀虫速度快、持效期长、对天敌安全、对环境友好等优点，是防治稻纵卷叶螟的理想药剂之一，在我区具有很好的推广前景。 关键词：稻纵卷叶螟  10%氟虫双酰胺.阿维菌素SC  防治效果   Cnaphalocrocis medinalis Guenee analysis of field experiment Abstract: Study on Effect of 10%  Flubendiamide Avermectins SC on Rice Leaf-roller and control efficiency. The new multiple range test. 10% of fluoride for every two-amide insect. more than avermectin SC 450ml. Control effect of rice leaf roller and 20% per hectare Chlorantraniliprole the effect of polar 150ml significant difference, and the persistence up to 20 days. And 10% of fluoride per hectare insect double amide avermectin 450ml on the old rice leaf-roller equally good effect. 10% lubendiamide Avermectins Tang brand name rice (6.7%Flubendiamide +3.3% Avermectins) Bayer CropScience offers. With anti-efficiency killing speed persistence length the safety of natural enemies environmental friendliness is ideal for pharmaceutical control of rice leaf-roller in my area has a good promotion prospects.
