To prevent grasshoppers and aphids from destroying the sorghum (Sorghum vulgare) or chastiya crop, use one bagful of the branches of crown flower (Calotropis gigantean). The branches along with leaves are soaked in a big vessel containing water. This becomes the stock solution for spraying on the sorghum crop. Before spraying the solution, take out the used branches and place them at random in the field. This furthers the spraying effort. Farmer Naranbhai Sarvaliya has adopted this method out of experience.
