“…Integrated pest management (IPM), is a combination of cultural, physical, mechanical, botanical, chemical (when required) and other management methods which plays a significant role in countering the population of pest in a sound manner. Many researchers had already proven the usefulness of IPM integrating of each and all available components in managing the pest population of rice below those causing economic injury (Alam et al, 2016;Tanwar et al, 2016;Anurag et al, 2020;Jahnavi et al, 2022). Therefore, the present study was designed to assess the effectiveness of a knowledge based IPM module in insect pest management of rice as well as its economics, which is crucial from the perspective of the farmer.…”

Background: Rice is one of the most common cereal crops in India, which has been found attacked by several insect pests including hoppers, stem borer, leaf folder, gall midge and ear head bugs. Farmers typically employ insecticides as preventative and curative management which causes needless issues. Although integrated pest management (IPM) has been recommended to nullify the ill effects of chemicals pesticides, farmers are hesitant to employ the IPM’s components and mostly rely on pesticides. IPM integrates knowledge-based techniques of biological, cultural, physical, host plant resistance and chemical control strategies in order to limit pest populations considered economically acceptable. Present investigation was conducted to evaluate the effectiveness of IPM strategy improving upon the crop productivity. Methods: An Integrated Pest Management (IPM) module comprising of spacing, introduction of natural enemies, application of botanicals, entomopathogenic fungi, installation of yellow sticky traps and chemical pesticide (Thiamethoxam) was assessed in comparison with Farmers Practice (FP) (usual routine followed by the farmer during the cropping season) in the farmer’s fields. Result: The pooled mean data of per cent leaf incidence by Nephotettix virescens ranged between 4.59-6.25% during the two years research in IPM module, while in farmers practices mean leaf damage varied between 8.09-8.61%. Similarly, the leaf damage caused by Nilaparvata lugens ranged between 4.88-7.61% as compared to 8.64-10% in the farmers practices. The BC ration was recorded to be 1: 7.6 and 1:6.85 during 2018 and 2019, respectively.
