White ant infestation mostly occurs in black soils that are generally wet with high humidity. In such lands, Dhamajibhai Dihora suggests the spreading of common salt to prevent white ant infestation. Besides, he makes heaps of dry pasture around the field so as to draw the white ants and leave the crop alone. This is a traditional method used by farmers in the Sosiya area in Bhavnagar district.
Ingredients: Common Salt, pasture
