Details of Innovation	White fly causes immense damage to the leaf and sheaf of (Gossypium hirsutum). More damage is caused in the winter. Due to high moisture in winter, there is every chance of insect infestation. To control white fly on cotton, Ramanbhai Patel of Rajkot has come out with a major, commonsensical innovation. He takes a two-metre plastic paper-sheet and applies castor (Ricinus communis) oil on its sides. Two persons hold ends of the oily plastic paper on the two sides. They walk through the open lines by the cotton plants. When whiteflies fly from the cotton leaves and try to sit on the oily paper, they get stuck to the sticky sheet. Thus, the white fly insects are destroyed. About 50 to 70 per cent of the insects are thus controlled. This practice has direct effect on the insects because as soon as the white fly or other insects get stuck to the paper, they die.

PAS_1	"INSECTICIDES AND FUNGICIDES. - Kerosene oil, or coal oil, is a powerful insecticide; The undiluted oil is, however, liable to seriously injure plants to which it is applied. This difficulty is overcome by using one of the special spray pumps which have been devised for the purpose of mixing oil with water in any desired proportion; or by forming an emulsion with some substance that may be readily diluted with water. Soap is most commonly used for this purpose, as follows: Kerosene oil 2 gallons, Hard soap (preferably whale-oil) 4 pound, Water 1 gallon. Dissolve the soap in the water by boiling. Add the suds, boiling hot, to the oil. Churn the mixture violently with a spray pump until it becomes a thick creamy mass. If perfectly emulsified, the oil will not rise to the surface even after standing for an indefinite time. Such an emulsion may be used immediately or kept as a stock mixture. Before using, dilute one part of the stock emulsion with 8 or 10 parts of water. This will be an efficient remedy for green-aphis woolly-aphis, red-spider, mealy-bugs, and certain scale-insects." https://ir.library.oregonstate.edu/downloads/6d56zw96d
PAS_2	"Soap-Detergent Sprays: Now days, soap-detergent sprays are available in the market that are designed for the control of plant pests. These sprays have found to be highly effective against different small soft-bodied arthropods, like aphids, young scales, whiteflies, psyllids, mealybugs, and spider mites. Large insects, like - caterpillars, sawflies, and beetle larvae are normally immune to soap sprays. However, some large insects like boxelder bugs and Japanese beetles, are vulnerable." http://www.detergentsandsoaps.com/insect-control.html#:~:text=Soap%2DDetergent%20Sprays%3A%20Now%20days,%2C%20mealybugs%2C%20and%20spider%20mites.
