Ingredients The leaves and the bark of knobwood.
Details of Innovation Knobwood (Zanthoxylum chalybeum) can grow into a large tree if left unpruned. The bark has a grey colour and it is slippery. The leaves emit a lemony smell when crushed and the flowers are green-yellow. The fruits are red-brown and later turn purple on maturity. This is how it is employed in the storage of grain: a) Its leaves are pounded and then dried. This mixture is layered at the bottom of the granary and also in between and on the top of the grains in layers. b) The dried bark of the roots of knobwood are pounded and sieved. One kg of this powder should be mixed with two 90 kg. of grain.

PAS_1 "The insecticidal property of dry leaves of Vitex negundo against the Sitophilus granarius in the laboratory at (28±3) 0C and (78±3) % r. h. with Soxhlet extracted extracts of V. negundo leaves in ethanol, methanol, chloroform, acetone and n-Hexane were tested and found very effective to control the store grain insect pest. The biopesticidal effects of extracts in different solvents were compared by calculating LD10, LD50, LD90 and LD99 values for 96 hrs. The Probit analysis of data demonstrated that LD values for ethanol, methanol, chloroform, acetone and n-Hexane extracts were LD10 – 1.216, 1.141, 0.9298, 1.265, 0.5398 ml/Kg; LD50 – 2.997, 3.106, 2.490, 3.727, 1.302 ml/Kg; LD90 – 7.392, 8.457, 6.667, 10.98, 3.142 ml/Kg and LD99 –15.43, 19.14, 14.88, 26.50, 6.439 ml/Kg respectively, for 96 hrs."
