We have sowed Watermelon 25 days back. 10 days back the problem started for leaves. The leaves have wrinkles and for small leaves we have observed the dryness in edges. And the back side of leaves we see whiteness.
First we thought it is because of Mosquito and we have sprayed Rogger. But there is no use. But now we are worried this might be related to a pest disease.
Can somebody help me what to spray and how to deal with this issue?
