Monitoring Insect pest population and foliar disease on the early Potato crop and their impact on tuber yield in Punjab

摘要

Potato (Solarium tuberosum L) is the most promising non cereal food crop in the world for ensuring food an nutritional security in developing countries. Potatoes are vegetatively propagated crop, the rate c degeneration is very high due to the accumulation of viruses in the rubers which are used as seed in ne> crop season. So the population of insect vector during the crop season has detrimental effect on the seei quality. From the three years of studies at ICAR-CPRS, Jalandhar has shown that in early crop whitefly i causing high incidence apical leaf curl virus and in the late sown crops aphid vectors are causing sever mosaic in the crop due to transmission of virus complexes. Seed window for potato seed production unde seed plot technique for northwestern plains has narrowed down.
