Bhikhabhai Makwana of Prempura village of Visava Dar of Junagarh, Gujarat, has used his keen sense of observation to suggest an innovative way to keep ungulates, such as deer and blue bull, away from agricultural fields. Ungulates cause a lot of damage to crops. They are natural prey for lions and use their sharp sense of smell as survival instincts. They always desist from straying into the areas which are frequented by lions. The smell of of the excrement of lions deters them. Realising this behaviour of ungulates, Makwana collected the excrement of lions from the Gir forest in Gujarat and sprinkled its dry powder around the perimeter of the crop area. He claims that the smell of the excrement shields the crop area against the intrusion of ungulates. Sprinkle the powder of the dry feces of lions on the prephery of a crop area.
Formulation: The powder of the dry excrement of lions on the periphery of a field
Ingredients: Lion excrement
"Evaluation of the tobacco plant as botanical pesticide [1994] - The effectivity of tobacco spray and tobacco leaf dust against insect pests of tomato, cowpea, mungo, eggplant, garlic and corn under field conditions was evaluated. Tobacco aqueous spray was prepared from ground tobacco leaves at 1:10
tobacco: water ratio. Ground tobacco leaves were used as powder dust. Water alone and two standard insecticides, Lannate and Decis, were used as controls. Treatments were applied at 10 days interval. Tobacco spray was effective against beanfly and bean aphid with a population reduction of 89 percent and 97 percent, respectively. Tobacco dust was effective against tomato cutworm and beanfly reducing their populations by 89 percent and 79 percent, respectively. Leafhopper, thrips and corn earworm were reduced by 50-69 percent using either tobacco spray or dust. Corn and tomato yields from plots sprayed with tobacco extracts amd cowpea yield from dusted plots were comparable to those sprayed with the check insecticides."
