Lalya is a local term used for the reddening of cotton plants. It has become a dreaded warning of crop failure. Lalya is caused due to a lack of micronutrients and moisture content in soils which are fast degrading. Scanty rainfall is a major cause of degraded soil. Bad soil health leads to low yields causing losses to farmers. Lalya is a complex process and unfolds with pest attacks, moisture stress and lack of micronutrients in the soil. Its seriousness increases due to temperature variation in the day and night. Due to all this, the plant's chlorophyll content decreases with nitrogen deficiency, giving birth to another pigment called anthocynin, which turns the plant red.
