【摘要】 用24%螺虫乙酯悬浮剂10 mL拌种300 g脱绒后光子棉种,以3%克百威颗粒剂50 g/m~2苗床营养钵撒施为CK1,空白对照为CK2。结果表明:螺虫乙酯悬浮剂包衣盲蝽棉苗危害率26%,防效35.8%,高于克百威颗粒剂撒施对照棉苗危害率4.5个百分点,防效低于克百威颗粒剂11.11个百分点,差异均不显著;螺虫乙酯悬浮剂棉苗危害率低于空白对照14.5个百分点,有差异,但不显著;2个对照之间差异显著。试验显示新内吸杀虫剂螺虫乙酯悬浮剂拌种包衣法防治棉苗床盲蝽可以取代高毒内吸杀虫剂3%克百威颗粒剂苗床撒施法。更多还原

【Abstract】 Coated 300g delinted cotton seeds with 24%spirotetramat SC 10 mL,surface dressing 50g 3%Carbofuran GR per square meter on seedbed as CKl,and blank control for the CK2.The results showed:in cotton seedling stage,the damage rate of cotton seedlings damaged by cotton plant-bug was 26.0%with 24%spirotetramat SC treatment,and the control effect was 35.8%,the damage rate was higher 4.5%and the control effect was lower 11.11%than the treatnent of CKl,but there was no significant difference;the damage rate of cotton plant-bug with 24%spirotetramat SC treatment was lower 14.5 percentage than the blank control CK2,there was differences,but no significantly,but there was a significant difference between CKl and CK2.The tests showed that the new insecticide 24%spirotetramat SC which coated cotton seeds in cotton seedbed seedling stage could replace the method which is high toxicity to human beings and livestock in seedbed with surface dressing 3%Carbofuran GR for controlling cotton plant-bug.更多还原
