Management of leaf-eating caterpillars in soybean crop
Soybean is an important food source and is considered both a pulse and an oilseed crop. However, it is largely used as an oilseed crop as compared to pulses. Soybean pulses is a great source of protein. Its main components are proteins, carbohydrates, and fats. Soybean contains 38-40 % protein, 22 %, oil, 21% carbohydrate, and 12% moisture.
In India, Madhya Pradesh is the largest soybean producing state and Soybean Research Center is situated in Indore, Madhya Pradesh.
Leaf-eating caterpillar in soybean crop causes major damage to the crop. Let us learn more about them.
• Grow Caster crop around the field. Adults of leaf-eating caterpillar prefer the castor leaves to lay their egg masses on it.
• Collect & destroy the castor leaves on which egg masses were laid.
• Spray SLNPV@ 250 LE in 500 litres of water per hectare during the evening.
• Spray bacterial based powder, Bacillus thuringiensis @ 15 g or Bouveria bassiana, a fungal-based powder @ 40 g per 10 liters of water.
• Spray neem seed kernel extract @ 5% or Neem based formulations @ 40 ml (0.15% EC) per 10 liter of water.
• On leaves with high infestation, spray Chlorantraniliprole 18.5 SC @ 3 ml or Profenophos 50 EC @ 10 ml or Chlorpyriphos 20 EC @ 20 ml or Indoxacarb 15.8 EC @ 10 ml per 10 liter of water.
