How Jujube Diseases and Pests Scientifically Medication
“Prevention as the mainstay and comprehensive prevention and control†is the total plant protection policy for pest and disease prevention. This policy should also be followed for the prevention and control of pests and diseases in jujube trees. To achieve this, we can reduce the number and amount of chemical pesticides used, and reduce the pollution of pesticides to the environment and fruits. Now we talk about the scientific use technology of pesticides on the prevention of pests and diseases in jujube trees. First, choose pesticides correctly When a juvenile farmer’s friend purchases pesticides, he must read the instruction manual in detail to understand the scope of use and the correct method of use of the pesticide. If in doubt, consult the pharmacy sales staff or the local forestry department. Second, symptomatic medication Every kind of pesticide has its best object of prevention and control. When carrying out pest control work, it is necessary to choose a pesticide with good control effect, low toxicity, and low residue for prevention and control. Avoid the so-called "insurance drugs" and "omnipotent drugs," and don't use the wrong drugs to avoid injury. Such as in the jujube tree flowering and young fruit prevention and treatment of Lumbosacosis, should choose a good suspension of imidacloprid suspension, both safe and good control effect; jujube rust, anthrax, and ring disease and other major diseases should choose safe Excellent anti-bacterial effects such as Danning, Dragon Light Fulian, Thiophanate, Taisheng and other high-quality fungicides are used interchangeably. After entering the high temperature rainy season, Bordeaux fluid should be used with caution, otherwise it is easy to produce phytotoxicity. Third, timely medication When carrying out pest control work, the most appropriate time should be selected according to the time and date of development of pests and diseases and the growth stage of jujube trees. This optimal time period is generally before the outbreak of the disease, the pests have not yet taken food or drilled heavily. The young age before the harm. At this stage, the worms are most sensitive to drugs and timely control can have a multiplier effect. Such as jujube rust from the young fruit period began to use fungicides alternately, dragon light Fulian and other fungicides, jujube fruit harvest will not occur jujube rust, but if the previous improper use of drugs, will cause a large area of ​​late jujube rust outbreak, even if Repeated use of the drug, the loss is difficult to restore. Therefore, most bactericides and insecticides do not work well, but miss the best use time. Fourth, grasp the amount of medication, water consumption When some farmers use pesticides, they often use more medicine and less water to reduce their workload. In fact, within the effective concentration of pesticides, the effect depends on the coverage of the liquid. When spraying insecticides and fungicides, sufficient water consumption is necessary because the eggs and germs are mostly concentrated on the back of the leaves and in the soil adjacent to the roots. If water is used at the time of spraying, it is difficult to spray the whole plant. Throughout, dead eggs in the dead, remnants can easily recurred. Blindly increasing the concentration of pesticides will increase the resistance of pathogens and pests. Excessive concentrations will also cause injury. According to the degree of occurrence of diseases and insect pests, jujube trees should be selected according to the degree of occurrence of diseases and insect pests. When spraying, it is advisable to use uniform medicine on the back and front of leaves. Fifth, using the "secondary method" to dilute pesticides First, dilute the pesticide formulation with a small amount of water into a "master solution", and then dilute the "mother liquor" to the required concentration. This will not only increase the availability of pesticides, but also avoid phytotoxicity due to uneven dilution. Six, choose a good performance of the spraying equipment Should choose the regular manufacturers of medical equipment, regular replacement of worn nozzles. The herbicide spraying herbicide should be dedicated to avoid phytotoxicity. Seven, pay attention to rotating medication Even the best pesticides cannot be used continuously for a long time. Because, in a certain area, the use of a single pesticide for a long period of time will inevitably lead to a decline in effectiveness, leading to resistance to the control subjects. The correct method is to rotate and use different kinds of pesticides. For example, Amateur salt has a good effect on the occurrence of heavier giant bridge insects and bollworms on jujube trees. However, if used continuously for a long period of time, pests will produce resistance and the control effect will be greatly affected. Eight, pay attention to medication safety Pesticides are poisonous. During use, it is important to pay attention to safety and prevent poisoning. Applicators should wear long-fitting clothes, wear masks and gloves, and try to avoid contact between pesticides and the skin and nose and mouth; do not smoke, drink water and eat food when applying pesticides; wash with soap and water after contact with pesticides; When cleaning, avoid the source of drinking water for humans and animals. Once pesticide poisoning occurs, it should be immediately sent to the hospital for emergency treatment. Jujube trees are suitable for use before 10:00 in the morning and after 4:00 in the afternoon. Sunny days can't be used when the high temperature is noon, otherwise it is easy to cause phytotoxicity to the jujube tree or cause poisoning to the application personnel.
