Research On Low Public Hazard Integrated Control Technology Of Tobacco Pest

This research through investigating tobacco pest that taked place in southernShandong Province, found out heavier main target pest. Low public hazardprevention technology was researched for every main target tobacco pest, andfound out the suitable low public hazard prevention medicament. According todifferent seasonal trait of tobacco, coordinate and combine with cultivationtechnique, study the low public hazard integrated control technical regulationof tobacco, extend heavy area experiment rules.Specific result as following:1. Main target tobacco pest in southern Shandong Province.The investigation of tobacco pest, through combining fixed position anddetailed locality survey of the unit in district of Shanting, Yi'nan, Pingyi,Feixian, counted the area of emergence and loss of output on tobacco for pest.Further drawing a conclusion that tobacco main target pest was Tobacco ViralDiseases, Tobacco Black Shank, Tobacco Brown Leaf Spot, Heliothis assulta,Myzus persicae in southern Shandong.2. Low public hazard integrated control technical regulation of tobacco pest.Through comparing the effect of medicament experiment, found out thesuitable biological and low public hazard medicament. Combining tobaccobear period and pest period of taking place, in addition to using medicinesynthetically and mixing it with the culture measure and cutting leaf forge andusing low public hazard agriculture chemical Kejunkang etc, low publichazard integrated control technical regulation of tobacco pest was carried out.3.Large area experiment demonstration result of technical regulation of lowpublic hazard prevention of tobacco pest.Experiment of 3000 mu about low public hazard integrated control technicalregulation of tobacco pest was demonstrated and popularized inShanting.Control efficacy of plant diseases and insect diseases were over 80%and 90% separately. The output raised more than 15% than the general land,and the proportion of first-class tobacco improved by 10% than the generalland.In all, the low public hazard integrated control technical regulation oftobacco pest had a high control efficacy, and was popularized and applied by alarge scale.
