STUDIES OF SMOKE GENERATOR OF DDVP INTUBATE

A smoke generator of DDVP intubate is made up of two parts, a hot supply and a main-pesticide. It is a new processing preparation. The main pesticide is DDVP that is sealed in a plastic tude. The hot supply should be packed in a bag of pplyethylene plastics and it is made up of several components, among which the oxidizer is ammonium nitrate, when used, by opening the seal of the hot supply, inserting the main pesticide and then setting an ignition wire afire, it will immediadely produce white thick smokes dispersed,’in air to control injurious insect. The release of the smoke generator is a handy and effectual measures that are used to control the forest diseases and insect pests under specific conditions. Each mu is generally applied 1 Kg. of the hot supply. The dosage of the main pesticide is depended on age of the insect.
