Contribution Rates of Integrated Prevention and Control of Rice Diseases and Insect Pests in Wan'an County
摘要
Abstract
[Objective]Rice is one of the most important food crops.The rice stem borers,rice leaf roller,rice planthopper,rice blast and sheath blight,all have significant influence on the rice production.This study was conducted to evaluate the contribution rate of the management of rice diseases and insect pests.[Method]In this study,three villages and towns were selected as representative sample sites,respectively.Taking no control of rice pests and diseases as control references,six management experiments of rice diseases and insect pests were carried out,i.e.,scientific control,unified pest prevention and control,farmers'self-control,no control of rice plant diseases,and no control of rice insect pests,etc.,to analyze the contribution rate of the management of rice diseases and insect pests.[Result]The results showed that the contribution rates of 5 different treatments were 38.60%,28.97%,27.16%,17.84%and 22.73%,respectively.Combined with the statistical areas and regions of low level,moderate level and outbreak occurrence of rice diseases and insect pests in Wan'an County in 2022,their contribution rates were 19.96%,21.59%and 26.01%,respectively.The total plant protection contribution rate of the control of rice diseases and pests in the whole county was 22.19%.[Conclusion]The results of this study have the theoretical significance and practical guiding value for evaluating the pest control and pesticide management measures of rice pests and diseases.关键词
