Method for controlling pests of farm crops

摘要

The present invention provides a method for controlling pests in a cultivation area for farm crops, which provides an advantageous effect on pest control in cultivation area for farm crops, the method comprising (1) a step for treating a crop seed with at least one type of compound selected from compound group A, (2) a step for treating a cultivation area for a farm crop with ethyl[3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-3-yl)phenoxy]-2-pyridyloxy]acetate, before, simultaneously with, and/or after sowing the crop seed obtained in the previous step, and (3) a step for treating foliage of the farm crop during a growing period thereof using at least one compound selected from compound group B. Compound group A: A group consisting of pesticidal compounds and nematicidal compounds such as neonicotinoid compounds, diamide compounds, carbamate compounds, organic phosphorus compounds, and biological nematicidal compounds, and bactericidal compounds and plant growth control agents such as azole compounds, strobilurin compounds, metalaxyl compounds, and SDHI compounds. Compound group B: A group consisting of bactericidal compounds such as strobilurin compounds, azole compounds, and SDHI compounds, pyrethroid compounds, benzoylphenylurea compounds, organic phosphorus pesticidal compounds, neonicotinoid compounds, and diamide compounds.
