The prevention and control of peach fruit borer should be combined with the prevention and treatment under the tree and the tree, and special attention should be paid to the prevention and control of the underground and the prevention and control of the first generation of peach, so as to fully control the damage of the peach borer.
Artificial control 1. Before the overwintering larvae were unearthed, the roots of the roots of the roots of the tree were split 13 to 16 cm, and the overwintering ridges were scraped off the attached surface. 2. When the first-generation larvae were de-fruited, the green manure was combined with the green manure to carry out pressing on the tree. 3. Remove the fruit. During larval pod damage (before larvae are de-fruited), the orchards are patrolled, infested, and killed within the fruit. The fruit was picked every 10 days and the amount of insects was effectively controlled.
Ground control 1. When the larvae are unearthed after soaking rain, ground control can be carried out in June, using phoxim particles, spreading 5 to 7.5 kilograms per acre (or phoxim that sprays 800 times) to mix the fine soil into poison. The soil is applied under the canopy, and the soil of the tree tray should be ploughed again after spreading the herb to improve the control effect. 2. From July to August, the peach was sprayed for 2 to 3 times with 1500 to 2000 times of liquid to kill eggs for fruit preservation. 3. Measures such as cover film on the ground after the spring and cultivation of soil under the tree are also effective agricultural technology measures against peach borer pests.
The tree is controlled in a serious orchard, and sprayed in each generation of adult emergence or egg generation. The light orchard is sprayed once during the hatching of each generation of eggs. The commonly used agents are: 10% Uranus emulsion 5000-6000 times liquid, 20% swab or 2.5% kung fu 2000 times liquid.
Chemical control In May, the overwintering larvae were excavated using buried larvae. When the larvae were unearthed in large amounts, soil pesticides were treated in time. From June to July, male moths were trapped with pheromone pheromones, and the moths were trapped at each trap. 3 to 4 heads 1 to 4 days after the appropriate period of spraying control, but also to do a good egg rate survey, when the egg rate reached 1%, it is timely to spray, to accurately grasp the occurrence of insect pests, determine the spray The scope and time of the medicine will increase the control effect.
