Abstract
[Objective]With the adjustment of planting structure and the change of planting area of cotton in China,the main diseases and pests are constantly evolving,especially in the case of the sharp fluctuation of cotton planting area in the Yellow River Basin.Clarifying the evolution characteristics of diseases and pests in this area can provide reference for scientific control.[Methods]Based on the relevant data of National Bureau of Statistics and National Plant Protection Statistics released by National Agro-Tech Extension and Service Center,the changing trends of cotton planting area,occurrence and control of disease and pest,and yield loss in the cotton planting region of the Yellow River Basin were analyzed.[Results]From 1998 to 2023,the cotton planting area of the Yellow River Basin and its proportion to the cotton planting area of the whole country increased first and then decreased.The occurrence area,control area,recover loss,and actual loss showed an overall trend of decreasing-increasing-decreasing.The total control area of disease and pest in cotton planting area of the Yellow River Basin is larger than the occurrence area.The occurrence area,control area,recover loss,and actual loss of pest are greater than that of disease.In order of average annual occurrence area from large to small,the major pests and diseases were Helicoverpa armigera,Aphis gossypii,cotton mirid bug,Tetranychus cinnabarinus,seedling disease,boll disease,Bemisia tabaci,Fusarium wilt,cotton thrips,and Ostrinia furnacalis.Over all,the occurrence area ratio of A.gossypii,cotton mirid bug,B.tabaci,cotton thrips,and boll disease showed an increasing trend,while the occurrence area ratio of H.armigera,seedling disease,and Fusarium wilt showed a decreasing trend,and the occurrence area ratio of T.cinnabarinus and O.furnacalis showed no obvious change.The actual losses of H.armigera,A.gossypii,and boll disease accounted for a large proportion.[Conclusion]The main pests and diseases in the cotton planting area of the Yellow River Basin were identified,which provided theoretical support for the prediction and prevention of cotton diseases and pests in production.关键词
