Control of Gallmidge

Control of Gallmidge

1. Avoiding staggered planting (complete planting in an area within 3 weeks) to reduce infestation.

2. Apply phorate 10G @ 12.5 kg/ha or carbofuran 3 G @ 25 kg/ha at 15 DAT in 1– 2 inches of standing water.

Management of Rice Gundhi bug

Chemical control: Spraying of Endosulphon 35 EC or Quinolphos 1.5% Dust @ 25 kg/ha, or Quinolphos 25 EC @ 1.5 liter in 500 liter water / ha is found to be highly effective in controlling the insect populations.

Biology of Rice Gandhi bug

Egg: Eggs are circular, brownish seed like, 2 mm long, laid in clusters in two rows along the midrib on the upper surface of the leaf-blade. Nymph: First instar is small, 2 mm long, pale green in colour, which grows to deepen green through different instars. Adult: Adults are greenish yellow, long and slender, above ½ inch in length with a characteristic buggy odour

Nature of damage of Rice Gandhi bug

1. Both adults and nymphs do the damage. The nymphs start feeding 3 to 4 hours after hatching.

2. They feed on the leaf sap near the tip/ on milky sap in developing spikelets at milky stage. Sucking of the milky sap causes ill-filled/ partial filled and chaffy grains.

3. Serious infestation can reduce the yield by 50%. The straw gives off-flavour that is unattractive to cattle.

Symptom of attack of Rice Gandhi bug

 

1. Leaves turn yellow and later rusted from tip downwards. Appearance of numerous brownish spots at the feeding sites / shrivelling of grains.
2. In the case of heavy infestation, the whole earhead may become devoid of mature grains. Its presence in the field is made out by its strong smell.
