The Application Of The Technology Of Pesticide Reduction Control Efficiency Increasing In Agricultural Pest Prevention And Control

Pesticide is the most one of the major measures for controlling plant diseases and insect pests in the agricultural production.Using pesticide chemical prevention and control of plant diseases and insect pests of crops is still the main method at present.But the negative effect brought by the extensive use of chemical pesticides has become increasingly serious.This paper investigated major crops diseases,insect pests occurrence and pesticide usage in recent years and conducted experimental demonstration of the relevant technology of pesticide reduction control efficiency increasing in Huoqiu County,Lu'an City.The technology of plant diseases and insect pests of pesticide reduction control efficiency increasing in the wheat-rice and oil-rice cropping pattern was improved in the northern Huai River.The main results and conclusions can be summarized as follows:1.We identified crop diseases and insect pests occurrence and discipline in Huoqiu County.The main diseases and insect pests were Sesamia inferens(Walker),Chilo suppressalis(Walker),Delphacidae,Cnaphalocrocis medinalis Guenee,banded sclerotial blight,false smut and rice blast in rice.The main diseases and insect pests were Aphidoidea,Tetranychus cinnbarinus,Rhizotonia cerealis van der Hoeven apud.Boerema&Verhoeven,FusaHum graminearum Sehw in wheat.2.We conducted experimental demonstration of the technology of pesticide reduction control efficiency increasing.The tests indicated that 'Jijian additives' could make the effect of conventional pesticide use in half and the efficacy not weakened in the prevention and control of Delphacidae in rice.The additives not only could control pollution reducing,also could let the farmers reduce the prevention and control of cost.Type of vibration frequency insecticidal lamp can traps in key subjects of rice insect pests,and insecticidal lamp on the natural enemies lure ability is weak,economic,ecological and social benefits are very obvious;Biological agents "1%lamictal toxin suspending agent mu with 40-60 g 3 can effectively control or reduce control wheat wheat gibberellic disease occurrence and harm,the work period is longer,the security of wheat.3.Through the analysis of the occurrence of the main pests and diseases and the demonstration of several techniques of decrement and synergism in the county,the application of the technology of pesticide reduction control efficiency increasing was further explored.Pesticide reduction pest control is a gradual process and each stage,each step should be scientific and reasonable arranged including adjusting measures to local conditions.It was more important not only to rely on the progress of green prevention,high-new medicament development and plant protection instrument progress,but also to improve the farmer's sense of responsibility and rich farmers of agricultural science and technology knowledge.
