Management of soil borne insects/nematodes/diseases plays a vital role for crop production. In the absence of exact estimates in India, it is nearly assumed that more than 50% of the crop loss is due to soil inhabiting microorganisms. lt is emphasized in this manuscript about integrated approach of soil borne insect-pest and disease management especially in the tropical and subtropical ecosystems. Integrated pest and disease management practices are useful in reducing the quantity and effectiveness of primary stages of soil dwelling arthropod pests or disease causing primary inoculums of pathogens below economic threshold levels. Sowing disease free seed or propagative material is of paramount importance as preventive measure. The proper seed treatment and cultural practices like deep summer ploughing, crop rotation etc. are suggested for minimizing the risk. lt is also advocated that the soil solarization significantly reduces the population of harmful soil organisms. The importance of different soil amendments are described for increasing antagonistic activities against soil borne pathogens. Use of bio-agents like Ttichoderma, Pseudomonas etc. has great potential to control the disease causing soilborne pathogens. Bio-pesticides/ botanical pesticides are comparatively slower than chemicals but have a great stability in managing pest population without affecting beneficial microorganisms. The techniques for controlling nematodes are also elaborated and it is emphasized to use trap crops like marigold, chrysanthemum etc. However, the limited use of chemical pesticides in high value cash crops is also suggested. There is an urgent need for balanced use of chemical pesticides and promotion of biopesticides for maintaining the ecology of soil micro-flora with sustainable pest and disease management.
