Management of Yellow Rust disease in Wheat

09/01/2019Posted on
  • Stripe rust is caused by the fungus.
  • It is easily distinguished from other wheat rusts by the orange-yellow spores.
  • Which produce small, closely packed pustules developing into stripes along the length of the leaf veins.
  • The spores occur on the upper surface of the leaves, the leaf sheaths, awns and inside of the glumes.
  • Pustules erupt within 10-14 days after infection.
  • Free moisture on the leaves and an optimal temperature (10-15°C) are required for infection.
  • The disease can cause up to 25% yield loss.

Managment-

 

  • Destroy volunteer wheat plants.
  • Crop rotation is very important in the case of yellow spot.
  • Growing resistant varieties is an economical and environmentally friendly way of disease reduction.
  • During the growing season active crop monitoring is very important for an early detection of diseases.
  • Avoid repeated use of fungicides with the same active ingredient.
  • Spray Kasugamycin 5% + Copper Oxychloride 45% WP 320 gm/acre or Propiconazole 25% EC 240 ml/Acre

Damage:-

  • Fall armyworm generally feeds on foliage, but during heavy infestations, larvae will also feed on corn ears. 
  • Foliar damage to corn is usually characterized by ragged feeding and moist sawdust-like frass near the whorl and upper leaves of the plant.
  • They will frequently be near the tip but may feed down the ear creating a track of damaged kernels.

Control:-

  • Set up of light traps.
  • Set up sex pheromone traps at 5 /Acre.
  • Apply any one of the following on presence of pest.
  • Emamectin benzoate 5% SG @ 100 Gm per acre.
  • Fipronil 5% SC @ 400 ml per acre.
  • Cloropyriphas 50% EC @ 400 ml per acre.

Irrigation management in watermelon

07/01/2019Posted on
  • Watermelon responds very much to irrigation but it can not withstand waterlogged condition.
  • It is generally cultivated as a spring-summer crop in which frequency of irrigation is very important.
  • The crop should be irrigated at 3-5 days intervals.
  • Soil moisture stress during pre-flowering, flowering, and fruit development stage drastically reduce yield.
  • Irrigation should be stopped during ripening as it adversely affects fruit quality and promotes fruit cracking.
  • Frequently irrigation promotes diseases on the plants for the controlling diseases control measure may be applied.

Seed treatment of Muskmelon

05/01/2019Posted on
  • The muskmelon is sensitive against frost and some diseases eg.powdery mildew, downy mildew, root rot, and yellow mosaic etc.
  • For the management of these diseases, before sowing seed treatment should be applied.
  • Treat seed with carbendazim 50% WP fungicide @ 2g/kg of seed.
  • Or apply Carboxin 37.5% + Thiram 37.5% fungicide 2g/kg of seed.
  • For the controlling of yellow mosaic virus, seed should be treated with imidacloprid 600 FS.  (48%) 1ml/kg seeds.
  • Then seed may treat with Trichoderma viride @ 4 gm per kg of seeds.
  • 20-30 min.time interval keeps for using next chemicals.
  • After treatment, dry seeds in shade and then do sowing immediately.

Management of Black Scurf Disease of Potato

03/01/2019Posted on

Management of Black Scurf Disease of Potato:-

  • The black scurf of tubers appears as a black crust on the skin due to the formation of fungus.
  • Rhizoctonia canker/black scurf occurs when stolons contact soil-borne fungal bodies.
  • Symptoms can be observed on above and below ground plant parts.
  • Symptoms observed above ground early in the season include necrosis at the tips of the sprouts and sunken lesions on stolons, roots, and stems.
  • Later in the season stems with cankers can become girdled, resulting in stunted plants.
  • Leaves of infected plants develop a purplish and chlorotic colouration.
  • The pathogen infects plant tissue and causes stolon blinding thus reducing tuber production and yield.

Management

  • Conduct a soil test prior to the establishment of the crop to know nutrient content and soil pH. Low pH is not conducive for disease development.
  • Use disease-free soil. Avoid areas with a history of potato production or history of potato scurf and stem canker.
  • Use certified potato seed and assure disease-free propagation material. If the seed is not certified, it should be treated with antagonists or fungicides before planting.
  • Apply Sulphur 90% WDG @ 6 kg/acre or Use Ammonium Sulphate as Nitrogenous Fertlizer.
  • For the better control of this disease, seed treatment must be applied with pencycuron 250 SC @ 25 ml/quintal tubers or Penflufen @ 10 ml/quintal tubers.
