AbstractBased on the practice of apple cultivation,the occurrence patterns,damaged partsand symptoms of the main diseases and pests of RedFuji apple trees were summarized and analyzed,and comprehensive diseaseand pest control techiquessuchasagriculturalcontrol,physicalcontrol,biologicalcontrolandchemical control wereproposed. The main diseases ofapples includedapple tree rot and apple ring rot,which mainly afect branches,fruits,leaves and other parts.Themain pestsof apples included Carposina niponensis,Grapholita inopinata,aphids,etc.,which mostly boreinto thefruitsinthe formof younginsects.In termsof agriculturalcontrol,choose fieldswith convenient transportation,flatground,easyiigationanddainage,fertilesoil,andgoodwaterandfertilzerrtentionperforance, such as slightlyacidicor neutral loam,to buildorchards.Select varieties that aresuitable forlocal climate and soil conditions,high yieldand high quality.Increase theapplicationoforganic fertilizersandtopapplycompoundfertiliers rich invarious nutrients.Conduct scientificfield management.Interms of physical control,inautumn,themainand central trunks offruit trees should be covered withsoil and whitewashed.Branches orsprouts should be usedas bridges to connecttotheupper and lower partsofthediseased scars to extend the lifespanof the fruit trees.Itisadvisable to deeply plow the tree pits and remove weeds in winter and spring to destroythe survival conditions of the larvae,setting upstickyboards,insecticidallamps,etc.intheappleorchard;intermsofbiologicalcontrol,artificiallyreleasenatural enemies such as predatory mites,ladybugs and spore-eating flies tocontrol pests;in terms of chemical control,give priorityto using low-toxicity pesticides and environmentall friendly pesticide formulations.After removing thelesions byscraping,applyhighly penetrating orsystemic agents.Thisarticle providesareference for the high yield and fruit quality improvement of apple trees.
