Publicity of pest control techniques for peach trees

The implementation of peach pest control technology is a comprehensive and systematic task, which needs to be closely combined with the occurrence law of diseases and insect pests and local climatic conditions. It is the basic principle to treat both diseases and insect pests and ensure nutrition, and comprehensive and scientific pest control measures should be implemented for peach trees. This is not only a necessary condition to ensure the normal growth of peach trees, but also an effective way to improve its economic benefits.

I. Peach bacterial perforation

1. It is necessary to strengthen the management of Taoyuan. When selecting the site of the orchard, avoid the areas where the groundwater level is high or the terrain is too low, avoid high air humidity caused by stagnant water; reduce the amount of nitrogen fertilizer when applying fertilizer to avoid greedy growth; at the same time, reasonable pruning is needed. Increase ventilation and light transmission, especially in summer, peach tree pruning needs to be appropriate, timely removal of such disease branches, the reduced disease branches will be concentrated burned. Meanwhile。 It is necessary to clean up the orchard thoroughly in winter to reduce the growth of overwintering bacteria.

2. Rational use of chemicals for prevention and control. Bordeaux solution is usually sprayed before peach tree germination, this Kobo solution needs to be sprayed after flowering, and wettable powders such as streptomycin and zinc Deisen need to be sprayed from May to August, which can effectively control this kind of disease.

Peach scab

1. Peach scab is a disease caused by bacteria, so it is necessary to prevent and control the reproduction and overwintering of the bacteria. Therefore, it is necessary to conduct a comprehensive and careful examination of the treetops during winter pruning. Once the diseased tips are found, they need to be cut off immediately, and the peach orchards should be comprehensively cleaned to reduce the existence of pathogens.

2. Secondly, in the planting of peach trees, it is necessary to control the density reasonably and prune scientifically to maintain the shape of peach trees. Avoid the contact between the crown and the crown, ensure sufficient light and ventilation for peach trees, and reduce the air humidity in the orchard during the rainy season. The use of chemicals. Pentachlorophenol sodium is usually sprayed before peach sprouting, and carbendazim wettable powder needs to be sprayed every 2 weeks from 2 weeks to July, which can effectively inhibit the growth and spread of bacteria.

Peach tree red-necked longicorn beetle

For the control of red-necked longicorn beetles, the effect of black killing is more significant because the decay path is irregular. In practice, it is necessary to clean up the dung at the location of the fresh faecal hole, then pry open the cortex around the dung hole with a small blade, and then put human aluminum phosphide tablets to kill its larvae. After putting the human reagent, the affected area needs to be covered with a mixture of 2% salt water and thin mud, and then wrapped with plastic film to ensure that the upper and lower parts are tied up. Operators need to ensure that gloves and masks are worn before carrying out prevention and control operations to avoid pests causing harm to the human body.

Fourth, peach gum disease

1. It is necessary to improve the soil and appropriately increase the amount of organic fertilizer, so as to improve the soil fertility.

2. It is necessary to ensure good drainage of the orchard and avoid stagnant water in the orchard, so as to reduce the air humidity and reduce the incidence of peach gum. At the same time, it is necessary to strengthen the physical protection of peach branches and reduce the probability of wounds in peach branches. In addition, if there is glue on the peach tree, it should be scraped off in time, then smeared with 5*Be stone sulfur mixture and 70% methyl topiramate at intervals of two days. In order to control peach gum disease.

As a good project to increase farmers' income, peach planting has higher economic benefits and can bring better benefits for peach growers. However, if the orchard is not managed properly, it will lead to a series of peach diseases and insect pests, which will directly affect the growth of peach trees. In serious cases, it will adversely affect the economic benefits of peach trees. Based on this, orchard managers need to carry out reasonable and scientific pest control of peach trees in accordance with the basic principle of "prevention first, combination of prevention and control", combined with local weather conditions and crop growth characteristics, so as to improve the growth quality of peach trees and ensure the economic benefits of peach orchards.
