In recent years, the use of fumigants in vegetables in greenhouses and greenhouses in China has become more and more important, which has played a very important role in increasing production. However, due to the strict requirements of the use of smoke agents, if used improperly, it is likely to cause phytotoxicity. How to avoid the toxic effects of smoked agents?
There is almost no limit to the use of each type of smoker product. Before using a certain smoke agent, you should be familiar with its characteristics and it is strictly prohibited to use it beyond the scope.
The smoke agent should be determined by the volume of space. Some product specifications are determined by the area of ​​the facility. Shorter sheds and small arch sheds are highly susceptible to phytotoxicity due to small space.
The distribution of smoke points should be uniform, otherwise it may cause local phytotoxicity, especially in small and medium sheds with uneven distribution of smoke.
It is advisable to apply the medicine after sunset in the evening. The higher the temperature inside the facility, the more susceptible it is to phytotoxicity.
Ventilation should be done after smoking. After igniting the smoke agent, the active ingredient of the pesticide is vaporized and rapidly cooled in the air to aggregate into fine particles, and the sediment adheres to the surface of the plant. 8 hours to 12 hours after the smoke agent is released, it is necessary to ventilate in time to remove harmful substances from the facility and avoid phytotoxicity.
