Brown Spot

23 March 2022
2 mins read

The fungus Helmintosporium oryzae causes brown spot disease in plantations. Brown spots can cause the death of young plants and reduce grain quality. Like Cercospora spot disease, this disease is very damaging to rice cultivation on land with poor drainage systems or land deficient in nutrients, especially potassium. The condition is rare in arable land.

The most common symptom of this disease is brown spots, oval to round in shape, about the size of a sesame seed, on the leaf surface, on the midrib, or the grain. Disease pathogens are seed-borne, so that disease can develop in very young plants under the right conditions. The disease can be controlled effectively with resistant varieties and through fertilization with 250 kg urea, 100 kg SP36, and 100 kg KCl.
