A New Pesticide Formulation - Heavy Smoke Agent
Smoke agent is an important dosage form in pesticide formulations, it is divided into light smoke agents, heavy smoke agents and aerosols. Heavy smoke agents are only used as poison gas in foreign countries and no report has been made for agriculture. In 1992, Nankai University conducted a trial of heavy smoke pesticides. The heavy smoke formulation studied by chemical expert Zhao Lining is a new formulation of pesticides, containing only heavy smoke carriers and pesticides. During the application, the smoke in the smoke layer is evenly distributed, the height of the smoke layer in the field can be adjusted with different control crops, and the time for the smoke layer to cover the ground can also be adjusted. Generally, a high control effect can be achieved in 40 minutes, and the smoke Under artificial control, they can all rise into the air and then spread again, or they can completely settle on the ground. The non-pervasive characteristics of smoke can effectively solve the problem of low efficiency of spraying technology treatment. Compared with aircraft control, the amount of pesticides is greatly reduced, and the pollution to crops, soil and water is very small; the amount of pesticides inhaled by workers when operating again is lower than international Standard intake, harmless to the human body. According to the researchers, using this technology, pesticide residues in crops can be reduced to a fraction or a fraction of the current level, which is much lower than international standards. The price of agricultural products can be increased and the income of farmers can be increased.
