Insect Control In Pigeon Pea (Cajanus Cajan)
About the Practice
Green larvae suck out the nutritive elements from the leaves of crops leaving them yellowish and drooping and eventually dropping off the plant. Besides, the larvae also eat up the pulses being formed. To control the pest, Kantibhai Vankar suggests that a two-kilogram solution of bitter gourd (Momordica charantia) be sprinkled on the crop of pigeon pea (Cajanus cajan) at the time of flowering. This prevents the green larvae infestation before pulses formation. Subsequently, pulses of good quality and higher yield will be produced. Kantibhai has learnt of this technique from his elders.
