Infestation of Mango leaf Webber in fruits
Leaf Webbers have been observed since the last 20-25 years but have not caused any harm; however, damage to mango fruit and leaves is observed for the first time in the Saurashtra region of Gujarat. The outbreak can also spread in other areas and neighboring states. The infestation is generally more likely to occur during April to November. Damage: Initially larva feeds on leaves by scrapping the epidermis. It later makes webs and feeds inside. Damage is also seen on mango fruits this year and is found to feed on pulp. If the infestation starts from the top side of the fruit, the fruits may drop. As a result, fruit quality deteriorates badly and it becomes unfit for marketing and consumption.
Integrated management: • Collect & destroy the rotten fallen fruits regularly. • Cut & destroy the damaged shoots and webs made by the larva periodically. • Follow regular pruning of trees to avail sufficient movement of air and sun light. • Install light trap during April to November in orchard. • Spray Bouveria bassiana@40 g/10 lit of water or Neem Seed Kernel Suspension @5% or neem base formulation 1500 ppm or 10000 ppm @10 ml to 40 ml per 10 lit of water at 10-15 interval. • On increasing the infestation, Spray profenophos 50 EC @ 10 ml or Novaluron 10 EC @ 10 ml or Lambda Cyhelothrin 5 EC @ 10 ml per 10 lit of water. • Maintain proper interval between spray and harvesting of mango fruits.
