In the initial stage of this disease, dark yellow coloured spots start appearing on the husks. These spots gradually spread and merge with each other. Due to this, the whole leaf turns yellow. Due to the yellowing of the leaves, many biological functions are adversely affected and the synthesis of essential food substances is not possible in the plants. Because of this, flowers are less on the plants and even if pods are planted, the development of grains is not possible in them. Whiteflies are this virus’s vectors and spread the disease to the entire crop.
Yellow mosaic disease control measures
To control this disease, apply yellow sticky traps in your field at the initial stage itself, which will help in controlling the white fly that spreads its infection. To prevent this, remove the affected plants from your field as soon as you see the symptoms of yellow mosaic disease on the crop. Spray recommended pre-mixed contact chemicals like Sperto (acetamiprid 25% + bifenthrin 25% WG) at the rate of 100 g per acre for control of white fly in such field to control white fly.
