Monitoring for Pest & Disease

• Undertake rapid roving surveys to detect and monitor pest and disease build up.
• Take visual observations at 5-10 km distance, and 12 spots/ha on both sides of the survey route.
• Observe at each spot, 5 plants to record pests/disease.
• Set up yellow sticky trap to monitor aphid population.

Pre-sowing stage 

• Deep ploughing to expose the soil borne pathogens and hibernating stage of defoliators.
• Destruction of plant debris.
• Early sowing to avoid damage due to mustard-aphid, and major diseases.
• For club rot management, soil amendment with lime (@ 1 kg/m2) to raise soil PH to 7.2 or apply Neem cake @ 0.5 kg/m2.

Sowing stage

• Irrigate the crop in IV week after sowing to reduce painted bug incidence.
• Spray the crop with 1000 ml Malathion 50 EC or 625 ml or Quinalphos 25 EC in 150 -200 litres of water per ha.
• Methyl parathion 2% @25 kg/ha for painted bug and mustard saw fly.
• Collection and destruction of gregarious stage larvae twice a week.
• Apply Carbendazim @ 0.1% a.i. or Apron 35 SD @ 6 g/kg seed against alternaria, white rust and other seedling diseases.

Vegetative stage 

• Spray the crop with 500 mJ Malathion 50 EC or Quinalphos 25 EC in 150- 200 litre of water per ha against sawfly.
• Collection and destruction of the gregarious stage larvae.
• Methyl parathion 5% dust @25 kg/ha
• Spray with Metalaxyl 8%+Mancozeb 64% WP 25gm/ha at situation of disease.
• Spray the crop Mancozeb 75% W.P. 1500- 2000 gm/ha at appearance of disease.

Flowering stage

• Destroy aphid infesting twigs at the initial stage of appearance.
• Spray the crop with one of the following insecticide: Oxydemeton methyl, Dimethoate,  Quninalphos, Malathion @ 625 - 1000 mi per ha
• Collection and destruction of gregarious phase larvae.

Fruiting stage

• Apply chemical control against aphid
