Sunflower (2012)

For management of Sunflower blight recommended seed treatment with Carbendazim 12% Mancozeb 63% WP 3 g/kg seeds and also spray crop with same fungicide 0.2% (20g/10 lit water) at 30 and 45 days after sowing. For management of Sunflower Downy mildew undertake two sprayings on crop with Difenconazole (25 E.C.) 0.05% (5ml/10 lit water) at 30 and 40 days after sowing.

Mango (2012)

Blightening of young shoot tip of Mango in rainy season can be control by three sprayings of Carbendazim (0.1%) or Difenconazole (0.05%) at 10 days interval For controlling the dieback in Mango graft it is recommended to take three spraying on planst with Carbendazim+Mancozeb (0.2%) or Difenconazole (0.05%) at 10 days interval.

Seed Pathology (2013)

Seed processing with polymers vitavax 200 has been recommended for better germination, field emergence, plant stand and to reduce seedborne pathogens.

Research Recommendation By P H Ghante (Pigeon pea)

National Recommendation For Organic Farming:

  • Management of pigeonpea wilt by Soil application (Application of Trichoderma harzianum 1% WP 20 kg in decomposed 500 kg FYM per hectare of farm before sowing) and Seed treatment with bio agent (Trichoderma harzianum 1% WP i.e. Domestic strain 12 g/ kg seed).
  • Recommended to make trenches (15 cm deep) within rows and borders parallel to slope to drain the excess water in water logging condition reduces Phytophthora blight disease incidence by draining excess water and avoid Phytophthora blight disease spread through water.
  • Management of Macrophomina blight disease by making trenches (10-15 cm deep) within rows and border across the slope hold the rain water and avoid moisture stress condition which reduces Macrophomina blight disease incidence in pigeonpea field and one irrigation at critical stage of pod formation in case of moisture stress saves the crop from Macrophomina blight aggravation.
  • Recommended the soil application of Arbuscular Mycorrhiza Fungi 10 kg/ha of farm before sowing for management of Macrophomina blight disease of pigeonpea.
  • Management of Cercospora Leaf spot disease by Seed treatment of Trichoderma sp. 1% WP 12 g + Imidacloprid 70 % WS 5 g + 25 g Rhizhobium + 25 g PSB per kg of seed followed by foliar spray of DAP 2 % + multi-micronutrient 2 ml / lit. of water or Spraying of Pseudomonas fluorescens 1.75% WP 5 g/lit. of water immediately after occurrence of fungal leaf spot disease in pigeonpea crop.
  • Foliar spraying of Pseudomonas fluorescens 1.75% WP 5 g/lit. of water is effective in reducing Alternaria leaf blight disease in pigeonpea crop.

National Recommendation For Modern / Conventional Farming

  • Management of pigeonpea wilt by Soil application (Application of Trichoderma harzianum1% WP 20 kg in decomposed 500 kg FYM per hectare of farm before sowing)and Seed treatment with systemic fungicide (Azoxystrobin 23% SC 1 ml / kg seed) or Seed treatment with combi fungicide (Tebuconazole 50% + Trifloxystrobin 25%WG 1.5ml/kg seed).
  • Seed treatment of insecticide i.e. Imidacloprid 70 % WS 5 g/kg seed followed by foliar spray of Fenpyroximate 5 EC 0.1% immediately after the occurrence of sterility mosaic disease is recommended for reducing the sterility mosaic disease spread and incidence.
  • Seed treatment of insecticide i.e. Imidacloprid 70 % WS 5 g/kg seed followed by foliar spray of Hexythiaszox 5.45% EC 0.08% immediately after the occurrence of sterility mosaic disease is recommended for reducing the sterility mosaic disease spread and incidence.
  • Management of Phytophthora blight disease by drenching of Metiram 55% + Pyraclostrobin 5% WG 0.2 %immediately after occurrence of Phytophthora blight disease and making trenches (15 cm deep) at seedling stage of crop within rows and borders which will parallel to slope of field to drain the excess water at water logging condition.
  • Recommended the drenching of Kresoxim Methyl 50% SC 0.1% or Copper Oxychloride 50 % WG 0.25%at pod formation stage of crop for management of Macrophomina blight disease of pigeonpea.
  • Management of Cercospora Leaf spot disease by Seed treatment of Trichoderma sp. 1% WP 12 g + Imidacloprid 70 % WS 5 g + 25 g Rhizhobium + 25 g PSB per kg of seed followed by foliar spray of Chlorothalonil 75% WP 0.25 % immediately after occurrence of fungal leaf spot disease in pigeonpea crop.
  • Recommended the Seed treatment of Trichoderma sp. 1% WP 12 g + Imidacloprid 70 % WS 5 g + 25 g Rhizhobium+ 25 g PSB per kg of seed + foliar spray of Chlorothalonil 75% WP 0.25 % or Benomyl 50 % WP 0.15 %immediately after occurrence of fungal leaf spot disease for management of Alternaria Leaf Spot Disease in pigeonpea crop.
