摘要
为探明稻-虾共作模式下水稻病虫害防治的适宜药剂,开展稻田常用农药对中华小长臂虾(Palaemonetes sinensis)的急性毒性测定.按照国家标准《GB/T 31270.21-2014化学农药环境安全评价试验准则第21部分:大型甲壳类生物毒性试验》方法进行.辽宁省稻田常用23种农药中,10％醚菊酯SC、60％吡蚜酮WG等2种农药,为高风险农药;50％噻嗪酮SC、5％阿维菌素EC、24％甲氧虫酰肼SC、10％溴氰虫酰胺OD、50％噻呋酰胺WG、30％稻瘟灵EC、50％嘧菌酯WG、9％吡唑醚菌酯CS以及70％戊唑醇WG等9种农药,为中风险农药;30％噻虫胺SC、30％噻虫嗪SC、20％氯虫苯甲酰胺SC、10％四氯虫酰胺SC、20％烯啶虫胺WP、8000 IU/mg苏云金杆菌SC、100亿孢子/g金龟子绿僵菌WP、35％三环唑SC、20％春雷霉素WG、2.4％井冈霉素AS、40％稻瘟酰胺SC和40％己唑醇SC等12种农药,为低风险农药.稻-虾生产田间推荐应用低风险农药防治水稻病虫害.
Abstract
To identify suitable agents for pest and disease control under rice-shrimp crop cultivation,the acute toxicity of pesticides used in paddy fields to the Chinese shrimp(Palaemonetes sinensis)was determined.Conducted in accordance with the method of the national standard GB/T 31270.21-2014 Test Guidelines for Environmental Safety Evaluation of Chemical Pesticides Part 21:Large Crustacean Biotoxicity Test.Among the 23 pesticides commonly used in Liaoning Province's paddy fields,two pesticides,10％ethermethrin SC and 60％pyraclostrobin WG,making them high-risk pesticides.Nine pesticides are medium-risk,including 50％thiamethoxam SC,5％abamectin EC,24％methomyl SC,10％bromoxynil OD,50％thiamethoxam WG,30％insecticide EC,50％pyrimethanil WG,9％pyraclostrobin CS,and 70％tebuconazole WG.30％thiamethoxam SC,30％thiamethoxam SC,20％clothianidin SC,10％tetrachlorvinphos-methyl SC,20％omethoate WP,8000 IU/mg Bacillus thuringiensis SC,10 billion spores/g Chrysosporium greenish WP,35％tricyclozole SC,20％chlortetracycline WG,2.4％validamycin AS,40％fenoxanil SC and 40％hexanazol SC,these pesticides are low-risk.In rice-shrimp production fields,low-risk pesticide applications are recommended for pest and disease control.
