Rice farming is essential for India’s agricultural landscape, but diseases like Sheath Blight pose a significant threat to crop yields. This disease, caused by the fungus Rhizoctonia solani, weakens rice plants, reducing grain quality and quantity. To protect your crops from this devastating disease, Katyayani Dr Zole is an excellent solution
What is Sheath Blight Disease in Rice
Sheath Blight typically infects the lower leaf sheaths of rice plants, creating large, oval-shaped lesions. As the disease progresses, it can spread to the upper leaves, inhibiting photosynthesis and leading to weakened plants and poor grain development. Uncontrolled, it can cause severe losses in rice yield.
Symptoms of Sheath Blight Disease in Rice
Sheath blight can affect paddy crops from the tillering stage through to the heading stage. The initial signs appear on the leaf sheaths close to the water level, where oval, elliptical, or irregular greenish-grey spots form. As these spots grow, their centres turn greyish-white with irregular dark brown or purple borders.
The lesions rapidly spread upward, merging to cover the entire tiller from the waterline to the flag leaf. When large lesions are present on a leaf sheath, they cause the entire leaf to die, and in severe cases, the whole plant may become blighted.
Infected plants, particularly older ones, are highly vulnerable, and when the infection occurs during the early heading or grain-filling stages, it leads to poorly filled grains, especially in the lower part of the panicle. In extreme cases, the infection spreads to the inner sheaths, leading to the death of the entire plant.
Environmental favourable factors for Sheath Blight in Paddy
Sheath blight in paddy is influenced by the following specific environmental conditions that promote the spread of the fungus
- Presence of sclerotia or infection bodies floating on water
- Sclerotia present in the soil
- High relative humidity between 96% and 100%
- Optimal temperature range of 28-32°C
- Excessive nitrogen fertilizer application
- High seeding rate or closely spaced plants
- Frequent rainfall
Katyayani Dr Zole: A Powerful Fungicide for Rice Protection
Katyayani Dr Zole is a broad-spectrum, systemic fungicide combining two potent active ingredients: Azoxystrobin and Tebuconazole. Together, they provide robust protection against Sheath Blight and other fungal diseases.
- Azoxystrobin (11%): Part of the strobilurin class of fungicides, it halts the fungus’s energy production by inhibiting cellular respiration, thereby preventing the spread of the disease.
- Tebuconazole (18.3%): A triazole fungicide, tebuconazole disrupts ergosterol synthesis in fungal cells, effectively damaging the cell membrane and killing the fungus.
Dual Protection: Inside and Out
Katyayani Dr Zole works by forming a protective barrier on the surface of the plant, while its systemic and translaminar movement ensures it penetrates deep into the plant tissues, offering both internal and external protection. This dual action makes it highly effective in preventing and controlling fungal diseases like Sheath Blight.
Dosage Recommendations for Sheath Blight of Rice
For managing Sheath Blight in paddy, use 300 ml of Katyayani Dr Zole per acre. Ensure uniform application for the best results.
Versatility of Katyayani Dr Zole
Dr Zole not only controls Sheath Blight in rice but also tackles a range of fungal diseases across various crops such as Tomatoes, Wheat, Potatoes, Onions, and Grapes. The key benefits of using this fungicide include:
