The indoor environment of the shed was closed, and various fungi and bacterial diseases gradually increased. Therefore, pesticides in greenhouses are used more frequently and the possibility of occurrence of phytotoxicity is greatly increased. The occurrence of injury in the shed is affected by the normal growth and development of vegetables, and even caused the whole shed to pull the garden. Therefore, the pesticide safety of pesticides in greenhouses must be given great attention by the vegetable farmers.
The safety precautions for the vegetables in the greenhouse are carefully selected: What medicine should be used for disease and should be placed in the seat. If the pesticide is not selected, it will not only fail to control the diseases of the vegetables, but also delay the timing of the prevention and control of vegetables, which will cause difficulties in the prevention and control of the vegetables and even cause phytotoxicity. Use with caution: When pesticides are used in greenhouse vegetables, they are only safe if they are used according to the pesticide instructions. However, in the actual prevention and treatment of vegetable diseases in greenhouses, vegetable growers often use a single agent to increase the dose or use multiple agents. This often exceeds the prescribed dosage and can easily cause phytotoxicity.
Shelves, vegetables, safe use of drugs, six pay attention to check the quality of pesticides attention: pesticides can easily cause damage after deterioration. Therefore, the physical properties of the pesticide must be carefully checked when purchasing the pesticide or before use. Attention concentration of compound pesticides: When pesticides are compounded, pay attention to the content of active ingredients of each drug so as to avoid repeated injury caused by repeated accumulation of the drugs. When taking care of compound concentration, the concentration should not exceed the range of safe use of pesticides. Mixed pesticides should pay attention to each other: Mixing pesticides can improve the control effect and control range, and can also delay the occurrence of pest resistance. However, if the pesticides are not used when they are mixed, they may cause pesticide failure or serious injury. For example, pyrethroid pesticides cannot be mixed with alkaline pesticides, and some pesticides cannot be mixed with copper preparations. Pay attention to the method and method of medication: pesticides that need to be mixed with some media, such as emulsifiable concentrate, wettable powder, etc. These pesticides need to be diluted with water or other media before they can be used. Therefore, it is best to use the medicine in the shed for present use. Spraying must be uniform, can not be repeated spray, can not apply too much in a certain part of the crop; smear must also be uniform, cut the original drug can not be used; Irrigation, fumigation also pay attention to the quality of spraying. Pay attention to the sensitivity of vegetables to drugs: Generally speaking, mature tissues have strong drug resistance, and young and old tissues are weaker. Therefore, there must be emphasis when spraying indoors. Some vegetables are sensitive to certain drugs, such as eggplant sensitive to carrageenan, winter Melon sensitive to Fumei, cabbage and other sensitive to copper preparations, if you do not pay attention, it is likely to cause injury. In addition, vegetables are also sensitive to pesticides at flowering. Therefore, it is more prudent to apply pesticides when the vegetables are flowering. Pay attention to the use of the drug environment: high temperature, strong light before and after noon application is more likely to occur phytotoxicity; shed ventilation is strong, the liquid evaporates too quickly, but also easy to increase the damage; winter spray when the water temperature is low, may also induce drug Harm occurred. Therefore, the greenhouse spraying should be conducted in the morning or in the afternoon with no dew or weak light. The ventilation during the spraying should not be too large. The temperature of the spraying water is preferably the same as the temperature in the shed.
