According to the pesticide network , the aerosol is prepared by a special method such as a pesticide, a heating agent, a combustion-supporting agent and a dispersing agent. It can be burned (without flame) when ignited, so that the pesticide is heated and vaporized and condensed into solid particles in the air. This pesticide is mainly used to control pests and diseases in forests, greenhouses and greenhouses, as well as warehouse pests.

In recent years, with the development of facility agriculture, the planting area of ​​vegetable greenhouses has increased year by year. Due to the unique microclimate of greenhouses and the cyclical effects of vegetable planting, some pests and diseases have become more serious. In the prevention and control of pests and diseases, a more effective one is effective. The means is to use smoke to control fumigation. It has high efficacy and low residue, saves time, labor, medicine, no equipment, is convenient to use, and generally does not cause disease resistance, avoiding conventional spray pesticides. Waste phenomenon. Therefore, many vegetable greenhouse growers often use aerosols to control pests and diseases. However, there are certain methods to be used when using aerosols. .
1, to be the right medicine. The performance of various aerosols is different, and its control objects are also different. Therefore, when using aerosols, only the type and degree of occurrence of the pests and diseases, the correct selection of the aerosols, and the right medicines can achieve the effects of high efficiency, saving money and labor saving. For the prevention and treatment of tomato and cucumber leaf mold in greenhouse, you can use serotonin aerosol; when controlling greenhouse downy mildew, blight, tomato early blight, late blight, you can use chlorothalonil aerosol for prevention and treatment.
2, to master the appropriate medication. In general, the use of drugs in the early stages of the occurrence of pests and diseases, the most effective. Because the amount of occurrence is small at this time, it is easy to control, and at the same time, the pest is in a young stage, and the natural resistance to the medicament is poor. If the mites are used to control mites, when the amount of mites is small, 250-300 grams per acre can be used.
3, to master the right amount of medication. The dosage of pesticides generally should be determined according to the size of the greenhouse, the extent of pests and diseases, and the effective content of aerosols. Under normal circumstances, 30% chlorothalonil aerosol, 10% quick-acting aerosol is used in a single dose of 0.3 to 0.4 grams per cubic meter, equivalent to 300-400 grams of aerosol per acre. If the pests are severe or the greenhouse is poorly enclosed, the dosage can be appropriately increased.
4, to master the time of medication. Generally, it is better to ignite the grass curtain in the evening, and it is better to ignite the aerosol in the cloudy and snowy evening. This is because under the sunlight, the surface temperature of the plant is the same as the temperature of the aerosol particles, the smoke is not easy to deposit and affects the efficacy, while in the evening or cloudy, it is conducive to the precipitation of smoke.
5, to master the method of medication. When using, do not put the tablets directly on the vegetable field. The scientific method is to put the aerosol tablets on the bricks, or to hang them on the wire in the shed, and keep the distance between the tablets and the tablets. For the large space of the greenhouse, when using aerosols with low active ingredient content (10%-30%), generally 3-5 firing points per acre, using high effective aerosols, each acre can be increased to More than 5; for the small space of the greenhouse, it is advisable to use an aerosol with a low active ingredient content, and set 7-10 discharge points per acre. After the tablets are placed, the greenhouse is closed and each tablet is ignited sequentially from the inside to the outside. Pay attention to blowing out the open flame, which is conducive to the generation of thick smoke, fumigation, continuous fumigation for 5 to 6 hours, that is, open the shed ventilation, smoked smoke every 7 to 10 days, continuous smoked 2 to 3 times can receive good results.
6, pay attention to safe and effective medication. When using aerosols, be sure to inspect the greenhouse or greenhouse so that they must be sealed. Also pay attention to safety. Aerosols are prone to moisture, and should be protected from moisture when stored. Once exposed to moisture, they can be placed in a ventilated place and dried slowly. Do not use fire. Take care to avoid crops and flammable materials when using the medicine. After ignition, the operator should immediately leave the shed and close the shed door. After 2 hours of ventilation the next day, the shed can be placed in the shed to prevent poisoning. Wash the soap with water after contact with the drug.
Tips for China's pesticide network : In the use of aerosols, we must first master the method of use, scientific and rational use, and play a better drug effect.
