In Karnataka Mandya district is one of the important paddy growing area. Mono cropping, faulty cultivation practices with continuous submerged conditions are causing higher pest and disease incidence and leading to lower yield. In this context KrishiVigyana Kendra, Mandya demonstrated integrated pest and disease management practices in 30 farmer’s field. The objectives of the study were to minimize the use of chemical pesticides and to establish the use of eco-friendly management practices.

Screening of okra genotypes was carried out under four different environments for shoot and fruit borer, yellow vein mosaic virus disease and enation leaf curl virus disease. The genotypes responded differently to different environments against different insect-pests and diseases. None of the genotype was found free from shoot and fruit borer infection, YVMV and ELCV incidence. However the genotypes that were found with some degree of resistance might be used for future breeding programmes.

Different colour sticky traps are commonly used for monitoring the population of many sucking pests such as thrips, whiteflies, leaf miner adults and aphids. They have also been used to monitor the natural enemies associated with the sucking pests. Presently, the monitoring the incidence of sucking pests in pomegranate using sticky traps is wanting. Hence, the study was conducted in pomegranate planting at orchard of Tamil Nadu Agricultural University, Coimbatore during 2016, using different colour laden sticky traps like yellow, pale yellow, green, orange and red.

Study on effect of dates of sowing on incidence of insect pests on castor genotypes revealed that incidence of Achaea janata was observed when castor was sown either early or late, however there was a decrease in larval incidence when the crop was sown late during the month of August as compared to that during July. Maximum of 2.73 larvae were observed on 48-1 when sown early which was reduced to 1.07 with late sowing.
