Girdle beetle management in soybean

30/07/2020Posted on
  • This pest causes lots of damage to soybean crops.
  • The female of this insect lays eggs inside the stem and when the girdle beetle emerges from the egg, they feed on the same stem and damage it.
  • This makes the stem hollow, causing the nutrients to not reach the leaves, resulting in dried leaves.
  • Due to this the crop production is affected   

Mechanical Management: –

  • Do deep plowing in an empty field during summer. Do not sow more dense crops.
  • Do not use high nitrogenous fertilizers, if the infection is very high, use appropriate chemicals.

Chemical Management: –

  • LAMBDA CYHALOTHRIN 4.9 % CS @ 200 ml / acre or PROFENOFOS 40 % + CYPERMETHRIN 4% EC @ 400 ml / acre
  • QUINALPHOS 25% EC @ 400 ml / acre or BIFENTHRIN 10 % EC @ 300 ml / acre

Biological Management: –

  • BEAUVERIA BASSIANA @ 500gram / acre

Girdle beetle in Soybean:-

Symptoms of damage:-

  • The inside of the stem is eaten by the larvae and a tunnel is formed inside the stem.
  • The leaves of plant of infected portion are unable to get the nutrient and are dried up.
  • In later stages the plant is cut at about 15 to 25 cm above the ground.

Management:-

  • Deep summer plough.
  • Intercropping with maize or sorghum should be avoided.
  • Crop rotation should be followed.
  • Avoid excess nitrogenous fertilizers.
  • Collect and destroy infested plant parts and egg masses.
  • Remove the infested plant parts at least once in 10 days and bury them in compost pit to monitor and reduce the populations of girdle beetle.

  Control:-

  • Apply phorate 10 G @ 10 kg/ha or carbofuran 3 G @ 30 kg/ha at the time of sowing.
  • Spray Quinalphos 25 EC or Triazophos 40 EC @ 3 ml/lit. at the crop age of 30-35 days and repeal after 15-20 days.
