The following practices are adopted to reduce the pest populations in paddy
Cultural
- Field sanitation
- Removal and proper disposal of stubbles will keep the borer population low in next crop
- Summer ploughing
- Mechanical picking of egg masses
- Late sowing should be avoided to keep the gal midges infestation under control
- Clipping of the affected fold leaves reduced caterpillar populations
- Use light trap reduce leaf hopper and leaf folder population
Chemical
- Dip the roots of seedling in 0.02% chlorpyriphos 20 EC + 1% urea for 4 hrs prior to transplanting
- Apply quinalphos granules at 1.0 kg ai/ha 10 – 15 days after planting
- The newly hatched borer larvae must be flit with 2 rounds of quinalphos or phosphomidon at 0.5 kg ai/ha at 7 days interval
- Dusting with malathion with effective against gundhi bug infestation.
- In case of army worm spray the crop in the evening after sun set with nuvan 0.5 kg a.i/ha
Biological
- Field release of egg parasitoid Trichogramma japonicum at weekly interval @ 50,000 ha during egg laying stage of rice borer in very effective
- Release of mired bug Cytorhinus lividipennis @ 50 – 75 egg/ m2
