Soybean Pests and Disease management Eng

Every year, the soybean crop is reported to be increasingly infested by Gram pod borer as well as Tobacco Caterpillar resulting in heavy yield losses.
They are polyphagus with more egg laying capacity and the larvae of this pest remain gregarious for 4-5 days and feed on the chlorophyll content of the leaves.
Infested plants can be easily spotted in the field. Later on, larvae disperse on neighbouring plants and damage the leaves by cutting big holes.

Use of recommended seed rate.
Install insect-specific pheromone trap at 4-5 locations in the field. Care should be taken to use clean cloth while handling the septa.
Use bird perches at 8-10 locations in the field facilitating easy access for birds to feed on insect larvae.
Regular monitoring of the field and destruction of egg mass/caterpillar in early stage of tobacco caterpillar.
Use castor as trap crop
Spray the crop with biological pesticides like HaNPV 100 LE/acre for Heliothis and SlNPV 100 LE/acre or Bacillus thuringiensis / Beauveria basiana @ 400 ml/acre.
Spray the crop with 1% Azadirachtin @ 400ml/acre.
Spray neemastra and brahmastra of 40-50 ml/lit water for the control of pests.
Spray HaNPV (10 larvae per 15-liter tank) mixed with 5 ml Ujala and 100 g jaggery.
For herbal treatment, apply a mixture made from pungent chili, ginger, garlic, onion, and a sticker at 900 ml per tank.
Use commercially available organic inputs such as Beauveria bassiana 1.15% W.P.
Additionally, install 10 pheromone traps and 1 light trap per acre for effective pest management.
