China's implementation of the "Agricultural Market Access System" and the launch of the "New Century Pollution-free Food Action Plan", the selection of pollution-free, safe, high-quality, pollution-free green vegetables has become an inevitable choice for people's safe consumption in the future, and now its new pest control The technical points are as follows:
Ecological control According to the law of vegetable pests and diseases and the required conditions, environmental factors such as temperature, light, water and gas are controlled in stages to prevent the occurrence of pests and diseases. For example, in the greenhouse cucumber production management, four-stage temperature change management measures should be taken one day to promote the growth of cucumber and reduce the occurrence of pests and diseases.
Biological control The use of natural enemies of pests and the use of biological pesticides, non-polluting plant pesticides to control pests and diseases, first of all to protect the natural enemies of pests, so as to achieve the purpose of pest control, bacteria treatment.
Chemical control In the process of chemical control, rational use of pesticides should be carried out, and the principle of “strict, accurate and appropriate†should be followed. Chemical pesticides used on vegetables should be selected from high-efficiency, low-toxic, low-residue pesticides to ensure the safety of vegetables. The safety interval of pesticides must be strictly enforced and the right medicine should be prescribed. And do a good job of forecasting and forecasting, so as to achieve targeted compliance and prevention. Chemical pesticides should not be used if they do not meet the pest control indicators, so as to reduce the number of pesticides used, to achieve pest control indicators, and to improve control effects. According to the law of growth and decline of pests and diseases and the distribution of pests in the field, the application time should be accurately selected; according to the distribution of pests and diseases in the field, the application method and the number of doses should be accurately selected, and the concentration and dosage of pesticides should not be blindly increased. In greenhouse vegetables, use more effective and efficient aerosols and dusts to control pests and diseases.
Physical control uses warm soup to soak seeds to kill some of the bacteria and eggs carried by the seeds, use solar high temperature disinfection and low temperature to kill the bacteria eggs in winter, and use the pest avoidance to drive or trap, such as using silver-gray membrane to avoid cockroaches and yellow boards to trap mites White peony, using sex attractants, sweet and sour vinegar to trap tobacco budworms, Plutella xylostella and other pests, using black light to trap tigers, carnation, and other pests.
