Sweet potato, Ipomoea batatas, is an herbaceous perennial in the family Convolvulaceae grown for its edible storage roots. The sweet potato plant is a branching, creeeping vine with spirally arranged lobed, heart shaped leaves and white or lavender flowers. The plant has enlarged roots called tubers which act as an energy store for the plant More than one thousand species of arthropod pests and nearly 400 pathogens are known to attack tea all over the world, though only about 300 species of insects and mites and 58 pathogenic fungi are recorded from tea in India. Crop loss due to pest and diseases varies between 15 and 20% 7.1 Major pests. Regardless of where lychee is grown, several insect groups attack the flowers, fruit, leaves and branches. Lepidopterous fruit borers are generally the most important pests affecting production. Other important species include various leaf- and flower-eating caterpillars and beetles, bark borers, scales, leaf mites, fruit. Integrated Pests and Diseases Management. Capsicum being relatively long duration (9-10 months) crop in polyhouse, the plant parts (vegetative, floral & fruit) are the more exposed to an adverse effect on the yield, quality and market value of the produce Basic requirements Rice is mainly grown in warmer regions as the plants will not grow at temperatures below 10°C. Rice is considered to be a semi-aquatic annual grass and is commonly grown in paddies in wetlands or under shallow water. Several new methods of propagating rice have been developed which allow rice to be cultivated in less conventional areas e.g. drought resistant varieties are.

The disease appears as on the foliage and pods. Infection is first apparent on the leaves as small slightly darkened areas, which later become white powdery spots

Disease symptoms The characteristic symptom of the disease is the white superficial powdery fungal growth on leaves, stalks of panicles, flowers and young fruits. The affected flowers and fruits drop pre-maturely reducing the crop load considerably or might even prevent the fruit set Pest and Disease Management: Common pests infesting vegetative propagules are mealybugs, scale and pineapple red mites. In addition to these pests, the diseases termed heart rot, root rot, fruit rot and butt rot may be major problems when handling, storing or planting fresh materials Symptoms PRSV-P Symptoms are typical of viral diseases. Papaya exhibits yellowing, leaf distortion, and severe mosaic. Oily or water-soaked spots and streaks appear on the trunk and petioles. The fruit will exhibit bumps and the classic ringspot. 16.
