Blast (leaf and collar) Disease of Paddy Crop

The concern of farmers has increased due to blast disease in paddy crops. These days, with the end of the rainy season, the temperature and humidity are increasing. Farmers have been advised not to use excess nitrogen.

What is the blast disease of the paddy crop?

  • The blast disease of paddy crops is caused by a fungus called “Magnaportheoryzae “. It can affect all parts of the paddy plant above ground.
  • The disease usually affects paddy crops in areas where soil moisture is low, frequent and prolonged showers and temperatures are low during the day.
  • Due to the difference of day and night temperature, dewdrops on the leaves freeze and thus the relatively cold temperature causes the development of this disease.
  • Blast disease is one of the most devastating diseases for the paddy crop. Blast infection weakens the plant itself at the planting or tillering stage (when the plant builds branches).

Control of Blast disease

The farmer should make balanced use of chemical fertilizer. It is necessary to apply Azacistrovin 25 sc, 500 ml, or Isoprothiolane 40 EC 750 ml per hectare for the blast as soon as symptoms appear on the leaf stage.In case of bacterial scorching, streptocycline 25 g plus copper oxychloride 500 g or Carbendazim 50% WP, 500 gm solution should be sprayed per hectare. This will eliminate blast disease in paddy.
