Abstract

The invention discloses a greenhouse insecticide fumigation agent which comprises the following components in parts by weight: 5-7 parts of ammonium nitrate phosphate, 1-2 parts of sulphur, 1.5-4 parts of sawdust, and 0.2-0.8 parts of DDVP (dimethyl dichloroviny phosphate). The obtained greenhouse insecticide fumigation agent is ignited by using a firing line, insufficient burning is as a main of the overall burning process to produce a great amount of smoke due to existence of sawdust, thus the purpose of killing insects is achieved by carrying the agent; and the greenhouse insecticide fumigation agent is fast to effect and has a good insect killing effect.

Description

Technical field [0001] The invention relates to a fumigant, in particular to a greenhouse insecticide fumigant and a preparation method thereof. Background technique [0002] Fumigant is a kind of pesticide that uses vapor generated during volatilization to poison and kill harmful organisms. Gaseous molecules enter the body of harmful organisms to act as a poison, and they have the form of liquid, solid or compressed gas that are easy to vaporize. It is especially suitable for application in warehouses, tents, houses, greenhouses, etc., which can be closed or nearly closed. When the fumigated objects are concentrated, it can effectively eliminate hidden pests or germs. [0003] The vapor of the fumigant generally enters the respiratory system directly through the skin or air valve of the pest, and then penetrates into the blood to cause the pest to poison and die. [0004] There are already some insecticidal fumigants used in greenhouses, which generally produce smoke after ignitin...
