Management Of Brown Spot In Rice/Paddy
The Brown spot in rice is also known as Sesame leaf spot, fungal blight or Helmintosporiose. The fungus can affect the seedlings as well as the plants on the main field.
The appearance of brown spots is the main symptom of this disease. The spots are seen in the sheath of the seedlings, leaf sheaths, and along the lead blades and glumes. These spots appear oval in shape or in cylindrical shapes. The brown colour of the spots gets deep and later gets a yellow halo around it. As the disease spreads, these spots become elongated and enlarged causing drying of the affected leaves. It can also cause browning of the grains affecting the quality and quantity of the yield.
Brown spot disease of paddy can seriously affect the yield, so it needs prompt treatments and preventive measures. It is important to apply the fungicides regularly.
