In response to the problems of increasing incidence of diseases and pests of peppers in greenhouse,a significant reduction in yield and quality of pepper caused by the continuous cultivation of peppers in greenhouse for many years,based on the characteristics and laws of the main diseases and pests in greenhouse peppers,a comprehensive mode of green prevention and control had been formed,mainly focusing on ecological regulation technology,biological control technology,pest trapping and killing technology,and scientific drug use technology through experiments,demonstrations and promotion,and had been continuously promoted and applied in production.By complicating the mode,the effect of disease and pest control had reached over 95%,the dosage of chemical pesticides had reduced by more than 50%,the qualified rate of pesticide residues had been 100%and the yield and quality of peppers had been improved.The above all ensured the quality and safety of agricultural products,and the ecological benefits were significant.The ratio of output to input was 6.78:1 in the green prevention and control area,which was higher than that of 4.68:1 in the conventional prevention and control area,and the net income was 4 111.0 yuan per 667 m2 higher than that in the conventional prevention and control zone,indicating good economic benefits.
