(Diseases and Management of Crops under Protected Cultivation) 5 Leaf miner Tomato, capsicum, cucumber 6 Thrips capsicum, cucumber, cole crops 7 Mits Tomato, capsicum, *cucumber 8 Powdery mildew 9 Damping off/Post damping off Capsicum, cucumber Tomato, capsicum 10 Root knot Tomato, nematodes capsicum 11 Fusarium wilt Tomato, capsicum 12 Late blight Tomato, capsicum Larve mine into the tender leaves in zig-zag manner and scrape chlorophyll. Photosynthesis is adversely affected, vitality is reduced and there is an appreciable reduction in yield. Affected leaves of plants become curled, wrinkled & gradually dry up. Feeding cause flower or leaf buds to abort or emerging leaves to become distorted. Small brown or yellow dotes on the leaves of plant are most easily observed sign of a mite infestation. Severely infested plant leaves become discolored, producing an unthrifty gray or bronze look to the plant. Leaves, buds and stem are cover with white powdery coating. Affect leaves curl upwards Failure of seedling emergence from the soil results in patchy appearance of seedlings stand in the nursery in early stages of growth. (Pre-emergence) toppling over of infected seedlings at any time after their emergence from the soil resulting in mortality of the seedlings. Root nodulation/galls on the roots. Yellowing and drooping of plants, wilting of leaves, stunting and browning of vascular system. The disease is characterized by the appearance of brown dead areas on leaves, which initially appear as faded green patches and later turn into brownish black lesions spreading rapidly during wet weather. Within 3-4 days of wet weather whole plant may get blighted. 13 Buck eye rot Tomato Spots on tomato fruit mark with pale brown, concentric rings resembling slightly the marking on a buck eye. 14 Septoria leaf spot Tomato The spots appear as small, water soaked, more or less circular spots in outline and show definite brown colored margins with grey centers.

(Diseases and Management of Crops under Protected Cultivation) 15 Bacterial wilt Tomato, capsicum 16 Blossom End Rot (Calcium deficiency) Tomato Sudden drooping of leaves, without yellowing resulted in wilting of the plants. Lesions appears at blossom end of the fruit. The affected portions of the fruit become sunken, leathery and dark colored. Pseudomonas fluorescens (10g/m 2 ), Bleching power (300g/200m 2 ), Streptocycline (0.1g/l) + Copper oxy-chloride (3g/l) Calcium Carbonate (5g/l) Major activities conducted by KVKs for Dissemination of Protected cultivation Technology : • Conducted training of farmers, personnel of various line departments on protected cultivation. • Organized FLDs/OFTs on farmers’ field to demonstrate new technology. • Organized exposer visits of farmers’ at KVK to demonstrate new technology on protected cultivation. • Motivations /Advisement of farmers towards protected cultivation. • Diagnostic visits of farmers’ field for identification s and suggestions for pest and disease management. • Published popular articles, extension bulletins, folders on protected cultivation. • Organized kisan mela, gosthi, farmer’s scientist interaction and workshop of farmers to create awareness among farmers towards protected cultivation. • Radio/TV talks on protected cultivation • Print media (Daily News Paper) and electronic media (Mobile Services, and voice sms) are used for quick information and message delivered to farmers. • Provided black polyethylene sheet, poly tunnels, quality planting materials and agrochemicals to farmers as new critical inputs.
