Selection of Green Plant Protection Schemes for Leeks
摘要
Abstract
To effectively control the pests and diseases of leek and pesticide residues,this study conducted experiments on different plant protection schemes,including treatment 1(chemical control),treatment 2(agricultural control),treatment 3(biological control),treatment 4(agricultural control+biological control),and treatment 5(agricultural control+biological control+chemical control),and the control(CK)was treated with clean water.The control effectiveness of diseases and pests such as gray mold disease,phytophthora blight,disease,dry tip,and thrips were evaluated,and the pesticide residues of each treatment and control were also tested.The results of the control effect test showed that treatment 1,treatment 3,treatment 4,and treatment 5 had a control effect of over 65%on gray mold disease and phytophthora blight,which was significantly higher than treatment 2(with a control effect of less than 40%).For the prevention effect of dry tips,treatment 2,treatment 4,and treatment 5 were all greater than 15%,significantly higher than treatment 1 and treatment 3(prevention effect less than 3%).The control effects of treatments 1,3,4,and 5 on thrips were all greater than 66%,significantly higher than treatment 2(1.20%).The pesticide residue detection results showed that six chemical pesticides,including thiamethoxam,highly efficient cyhalothrin,benzofenapyr,pyraclostrobin,pyrimethanil,and fludioxonil,were not detected in each treatment and CK(content less than 0.01 mg/kg).In treatment 1,propiconazole and bifenthrin were detected with concentrations of 0.46 and 0.24 mg/kg,respectively.There are currently no maximum residue limits for propiconazole and bifenthrin on leeks.Referring to the GB 2763-2021,both propiconazole and bifenthrin have lower pesticide residues on leeks than the reference limits.Based on the comprehensive results of disease and pest control and pesticide residue,the scheme of treatment 5 is most suitable for green production of leeks and can be widely applied.关键词
