摘要
狼毒是四川省牧区草原上主要的毒害草之一。施用48%盖灌能乳油3 750、4 500、5 250ml/hm^23个处理浓度,对草地狼毒进行防治试验。结果表明:该产品对昆虫安全,对人刺激性较小;施药当年3个处理浓度对狼毒的防效分别为89.86%、93.50%和94.53%,且各处理均对单子叶牧草产量没有显著影响;综合考虑药效显著性、经济成本等因素,建议在实际应用中采用4 500ml/hm2剂量进行防治。
Stellera chamaejasme L. is one of the main poisonous weeds in Sichuan pastoral grassland. Three concentration of 48% Garlon EC,3 750 ml/hm^2、4 500 ml/hm^2 and 5 250 ml/hm^2,were used to control against Stellera chamaejasme L. The results indicated that48% Garlon EC was safe for people and insect. Efficacy of three density were 89. 86%、93. 50% and 94. 53% in the first year,respectively,and didn’t impact on yield of monocotyledon forage grass. So the dose of 4500 ml/hm^2 was advised and used to control the weed considering the factor of significance and economy.
