Management of Rust disease in Wheat

20/01/2020Posted on
    • Leaf rust is caused by the fungus.
    • The first signs of the disease (sporulation) occur 10-14 days after infection
    • Leaf rust produces reddish-orange coloured spores which occur in small, 1.5 mm, circular to oval-shaped pustules.
    • These are found on the top surface of the leaves, distinguishing leaf rust from stem rust which is found on both surfaces of the leaf.
    • The spores require 15 to 20ºC temperature and free moisture (dew/rain/irrigation) on the leaves to successfully infect wheat.

 

Management-

  • Crop rotation is very important.
  • 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.

Application of Manure and fertilizers in Garlic

18/01/2020Posted on

Garlic can be grown in almost all types of soil, however sandy, slit and clay loamy soil are best for cultivation, however it can also be grown in clayey soil. In heavy clay soil garlic should be planted in raised beds. Soil should be well drained and should be capable of holding water during the growth phase. Ideal pH should be 6 – 7.5 with high nitrogenous fertilizers @ 40 kg/.acre for early vegetative, phosphorus @ 20 kg/acre for better root development, potassium @ 20 kg/acre for critical leaf development and bulb formation. Pungency in garlic is because of good sulfur content.  Sulfur should be given @ 20 kg/acre after plants  have come out and leaf development has started for better pungency. Also mix the FYM at the @ 4-6 tonnes /acre at the time of preparation of the soil.
