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。
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.
