1. The amount of aerosol used In the greenhouse, the use of aerosols, the amount can not be simply calculated according to the planting area, should be calculated according to the space volume of the greenhouse. In general, 20-25 grams of aerosol is used per 100 cubic meters of space.
2. How to use the aerosol The aerosol should be placed away from the plant body, usually by placing it on the aisle and igniting one by one from the inside out. In windless weather, the airflow in the shed is relatively stable, and the aerosol placed in the middle of the shed should be slightly more than two to extend the residence time of the smoke indoors. If it is used in windy weather, because the airflow direction in the shed is opposite to the outside world, the aerosol should be placed more in the leeward, and the airflow in the shed is used to evenly distribute the smoke to various places in the shed.
3. Time of use The penetrating power of the aerosol to the water film is very weak. If the surface of the plant has a water film when using the aerosol, it is difficult to achieve the control effect. Therefore, the time of using the aerosol should be selected after the venting of the shed is closed in the afternoon, and when the surface of the plant leaves is not dew, it can be used around 4 pm.
4. Precautions Because there are fewer types of aerosols, using the same aerosol for multiple times will make the pathogens resistant and reduce their control. Therefore, in order to improve the control effect of aerosols, the use of similar conventional pesticides, such as chlorothalonil and ket, should be reduced. If these pesticides are used in the usual prevention of disease, the pathogen will prematurely become resistant to the aerosol, and when such aerosols are used later, the control effect will be greatly reduced. 
Essentials for using aerosols in greenhouses
Aerosol is a new type of pesticide that can produce smoke after ignition. The active ingredients in the smoke will kill the pathogen and play a role in disease prevention. The advantages are: simple usage, saving labor and time, and not increasing the humidity in the shed. Because the aerosol also contains some substances harmful to the crops, when the dosage is too large, it will cause damage to the plants, but the surface cells of the leaves will be necrotic, the leaves will be discolored and chlorotic, and the leaves will dry and die; if the dosage is too small, it will not start. To prevent and treat. Therefore, it is necessary to master the correct method of use in order to achieve good control effects.
