Bacterial leaf blight threatens second season paddy crop in Alappuzha

The Kerala Pest Management Center (KCPM) issued a warning on the eruption of bacterial leafburn disease in paddy areas under five Krishi Bhavans in the Alappuzha region.
Authorities, the disease in the Karuvatta, Nedumidi, Kainakary, Thakazhi and Neelamperoor’da confirmed, he says. Bacterial infection was detected in the fields that underwent paddy cultivation between 35 and 85 days from planting.
Authorities say that effective control of the disease is only possible when preventive measures are applied at the initial stage. Bacterial cells accumulate in the vascular tissues that absorb water and nutrients of the plant, thus preventing the upward movement of these vital sources. A visible symptom of the disease is leaf fading. Existing weather conditions are quite suitable for the spread of the disease. A KCPM official said that it could spread rapidly from the rain and that it could enter the themes of wind and winds between the leaves and enter the fields.
KCPM proposed the following control measures: Green cow manure can be connected to the muslin cloth and placed next to the water inlet or cow fertilizer can be poured into the paddy field. Alternatively, the bleaching powder can be placed in small muslin gland bags of 2 kg per acre near the water inlets.
In the first stages of the disease, 100% (bionol) per 10 liters of water can be mixed with 3 ml wetting agent, such as Filwet or Teepol. Make sure the upper leaves are thoroughly soaked.
If the disease is more common, streptocycline (2 grams) and copper oxycloride (3 grams) can be solved and sprayed with 3 ml filwet/teepol in 10 liters of water, each.
For farmers who follow organic methods, 20 grams of pseudomonas fluoresin in 1 liter of water or 1 liter of water, each Pseudomonas Floresin and Bacillus Subtilis, each with 3 ml filwet per 10 liters of water, can be sprayed.
Foods such as potassium and silica increase disease resistance. In 10 liters of water and spray 100 grams 13: 0: 45 leafy fertilizer, 25 ml silica and 4 ml filwet/teepol dissolve. Avoid continuous water stagnation. Drying the area intermittently can reduce the spread of the disease. However, in high acidic soils, attention should be paid to prevent excessive drying.
