Grasshopper, cricket menace
Is there any method to control grasshopper and cricket menace in my fields? The chemical sprays that I use for controlling them at regular intervals are not so effective.
In Gujarat, farmers control insects such as hairy caterpillar, grass hoppers and mole crickets infesting their crops by digging a trench about 1-1.5 feet depth all around their fields and filling it with water. The insects they say cannot cross this trench filled with water and drown in it. – Source Honeybee- 2(1):15, 1991
