LATEST RECOMMENDATION IN DISEASE MANAGEMENT
Management of Brown Leaf Spot of Rice (Drechslera oryzae)
- Use moderately resistant varieties e.g. IR36, Rajendra Bhagwati, Dhanlaxmi, Prabhat, Rajshree
- Seed treatment with Carbendazim 50 WP@2g/kg
- Spray Mancozeb @2.5g/Lit or Hexacanazole @ 2 ml/Lit just after appearance of initial symptom.
- Apply balanced doses of NPK fertilizers.
Management of Sheath Rot of Rice (Sarocladium oryzae):
- Seed treatment with Carbendazim 50 WP@2g/kg of seed.
- Spraying of Carbendazim @ 1 gm/Lit or Mancozeb @ 2 g/Lit at boot leaf stage and 15 days later.
- Adopt optimum spacing, avoid excess nitrogen.
Management of Bacterial Leaf Blight of Rice (Xanthomonas oryzae pv. oryzae)
- Grow moderately resistant varieties like Ajaya, IR64, Saket-4, Rajshree, Prabhat, Rajendra Bhagwati etc.
- Spraying of mixture of Agrimycin 100 and Blitox-50/Fytolan can significantly reduce the disease in field.
- 60-80 kg N/ha with required potassium may be recommended in endemic areas.
Management of Leaf Blight of Maize (Helminthosporium maydis)
- Use tolerant varieties viz; Shaktiman-1,2,3 & 4, Suwan, Ganga Safed -2, Deccan, Ganga-4, Ganga-5,Kisan and Jawahar.
- Seed treatment with Captan or Thiram @ 2.5gm/ kg seed.
- Spray Dithane Z-78 @ 2.5 kg/ ha in 1000-1200 liters of water, as soon as first symptoms of disease appear in the field.
Management of Wilt of Chickpea (Fusarium oxysporum f. sp. ciceri)
- Treat seed with Bavistin + Thiram (1:2) or Carboxin + Thiram (1:2) @ 3.0 g/kg seed.
- Grow improved varieties- G-114, Awardhi, Gaurav, Udai.
|Management of Panama wilt (Fusarium oxysporum f.sp. cubense ) of banana|
|The treatment involving disease-free suckers from a disease-free field + dipping in carbendazim (0.2%) for 45 minutes followed by carbendazim drenching (0.2%) and carbendazim injection @ 3 ml of 2% solution during the 3rd, 5th and 7th month after planting (MAP) was found to be effective (wilt incidence of 6% as against 80.33% in control) in reducing wilt incidence.However, bio-control agents i.e. Trichoderma viride (@ 10g/sucker three times) used as soil application also found highly effective and causes marked suppression of Panama wilt so may be included in integrated crop management (ICM)/ integrated diseases management (IDM) schedule in strict organic system.|
|Integrated management of citrus canker (Xanthomonas axonopodis citri)|
|The most effective treatment for management of citrus canker was combined application of Copper oxychloride (CoC) @ 3g per litre+ Streptocycline @ 0.3 g per litre which showed least lesion/leaf i.e.8.20 lesion/leaf. This was followed by spraying of Copper oxychloride (CoC)@3g per litre showing 15.75 lesions per leaf which was statistically at par with treatment of 2% Neem seed kernel extract as spray which exhibited 18.75 lesions per leaf.|
|Integrated management of papaya ring spot virus|
|Raising of papaya seedlings under Nylon net (40-60 mesh) and spraying of Acephate 1.5g per litre, 3 days before planting+ spraying of Urea @ 10g/liter + Zinc sulphate @1.5g + Boron @ 1.0g per litre before flower initiation stage was found to significantly suppress the incidence of PRSV at the early stage of plant growth. The treatment was found to have significant effect on increasing fruit yield (50.8Kg/plant) as compared to untreated control (27.0kg/plant).|
Management of Phytophthora foot and leaf rot of betelvine
- Sanitation of Bareja
- Drenching of Bordeaux Mixture (1%) after onset of Monsoon followed by soil application of bio-agent –Trichoderma viride incubated in MOC(5kg TV/500kg/.ha) and one more drenching of Bordeaux Mixture (1%) after 60 days of 1st drenching
Management of Crown Gall of Coriander
- Seed treatment with Pseudomonas talc formulation @ 0.40% followed by its foliar spray @40% at 45, 60 & 75 day after sowing can be recommended to manage stem gall disease of coriander caused by Protomyces macrospours.
- Alternatively, seed treatment with Hexaconazole @0.20% followed by its foliar spray @0.20% at 45, 60 & 75 day after sowing can be recommended to manage stem gall disease of coriander caused by Protomyces macrosporus.
|Management of Alternaria blight of mustard: Seed treatment with Propiconazole @ 0.1% followed by its foliar spray @0.1% at flower initiation stage can be recommended to manage Alternaria blight (Alternaria brassicae) disease of mustard.|
