Integrated Pest and Disease Management
- Follow crop rotation by non host crops and clean cultivation by destroying plant debris of previous season.
- Use of drip irrigation over conventional irrigation to avoid disease outbreaks.
- Application of high rates of calcium superphosphates and potassium fertilizers increases endurance in plants, while lower or higher rates of nitrogen increases disease/pest occurrence.
- Provide good drainage through raised beds in Kharif to minimize soil borne diseases.
- Seed treatment with Thiram + Carbendazim (2:1) @ 3g/kg seed or Trichoderma spp. @ 4-6 g/kg seed
- Multiply 2 kg of Trichoderma spp. in 1 quintal of FYM and apply in one hectare.
- Dip the seedlings in 0.025% carbosulfan + 0.1% carbendazim solution for 2h before transplanting in the main field.
- Plant 2 rows of maize or outer row of maize and inner row of wheat surrounding onion crop (250sq.m) at least 30 days prior to transplanting to block adult thrips.
- Initiate foliar sprays of pesticides from 30 days after transplanting or as soon as the pest/disease appears in the field.
- Spray insecticides when thrips population crosses economic threshold level (ETL) i.e. 30/plant.
- Spray fungicides and pesticide in combination for effective management of pest and diseases.
Mancozeb @ 0.25% with Methomyl 40% SP @ 0.8 g/l at 30 days after transplanting,
Tricyclazole @ 0.1% with Carbosulphan @ 2 ml/l at 45 days after transplanting
Hexaconazole @ 0.1% with profenofos @ 1 ml/l at 60 days after transplanting.
However if disease/pest incidence is higher, then one additional spray of any of the above combination should be taken.
- Spray at 10-15 days interval depending on insect pest /disease intensity.
- Always add spreader @ 0.5-1.0%
- Avoid repeated application of pesticide belonging to same class.
