Crop and Pest
Stage of the Crop
Symptoms of Damage
1. Stem Borer
Tillering to panicle
Larva damages the central shoot at the bottom which
dries up, it is referred to as dead heart. If the attack is at
the panicle stage white ear head with chaffy grains are
Endosulfan,35 EC 2ml./litre,
Quinolphos 25 EC 2 ml./litre
Trichograma sp. (Release
50,000/ha),Clipping seedling tips.Acephate 75%
SP2ml/litre,Neem (0.03 Ec) 5 ml perlitre
2. Brown plant hopper
Tillering to ripening
Both adults and nymphs congregate on the stem and
leaves just above the water and devitalize the plant by
sucking the plant sap. In severe infestation, seedlings
show burning symptoms in concentric patches, which
leads to hopper burn. While spraying direct the nozzle
towards the base of the plant.
Integrated Pest Management
Avoid excess use of “N” fertilizer.Transplant at recommendedspacing.
Set up light traps Avoid spraying insecticides
which causes resurgence likemethyl parathion etc.If the incidence is more, drain-out water from field for 5 to 6 days, Monocrotophos 36 SL 1.3 ml/lt. (while praying direct the nozzle to the base of the plant)
3. Gall midge.
Seedling, tillering and
boot leaf stage
The maggots burrow into the shoots at the bottom
resulting in long hallow characteristic galls or silver
shoots preventing the formation of ear heads.
Carbofuran 3% granule at 15kg. per hectare or use
of resistant varieties.
4. Paddy Hispa
Early stage of the
Adult beetle scrape the green matter of the leaf causing
characteristic white parallel streak. The grubs mine into
the leaves and produce blotches.
Quinalphos 25 EC,2 ml./lt. or Phosalone 35 EC,2ml./lt.
