In the coming year, the overall incidence of fruit trees may be more serious When interviewed by reporters, Chen Lin’s agronomist said that according to the condition of northwestern fruit trees and the analysis of climate and environment this year, because of the old fruit area of ​​Weibei in Shaanxi, fruit trees are affected by factors such as large tree age, weak tree vigor, extensive management, and uncontrolled disease and pest control. In particular, affected by the special climate in the early part of this year, which is warmer and later wet, the winter survival rate of fruit trees and insect pests in Shaanxi, Gansu and other provinces will exceed 10% in previous years. Among them, apple rot disease, early defoliation, gold-lined moths, scale insects, leafhoppers, pear hibiscus, pear stem bee, leaf roller moth, etc. should pay attention to prevention and treatment. Serious fruit tree rot disease According to a survey of the apple growing areas in northwest China, apple rot disease has occurred in a wide range in recent years. It ranges from saplings to senile trees to varying degrees. Some trees even die, causing the destruction of gardens. As a "cancer" of fruit trees. Every year, the prevention of rot disease is a problem that local governments and plant protection workers and even the Ministry of Agriculture have to pay attention to. Extensive apple rot disease has brought haze to the development of the apple industry. Fall leaves fall in autumn and winter, fruit trees go into dormancy, and various pests begin to search for places to hide in winter; exactly where is their habitat? The tree, the old bark, the corners of the branches, the weeds around the trees, and the underground stone crevices are the places where the pests have passed their winter hide-outs and come back in the coming year. Most of these pests are apple borer, pear borer, and peach. Small pests such as fruit borer, leaf roller moth, beetle, defoliation, anthrax, scab, ringworm, brown rot, and powdery mildew. In order to eradicate pests and diseases, reduce the wintering base of pests and diseases, and produce high quality pollution-free fruits, the following points should be achieved. Scrape: At the beginning of autumn and winter, scrape off the old skin and avoid scraping the bark and leave it under the tree. Clear Garden: Remove dead branches, fallen leaves, weeds, bark, and fruit drop out of the orchard or mash or burn. When cutting in winter, pay attention to diseased branches, worms, dead shoots, stamens, etc. to remove overwintering pests. Habitat. Pharmaceutical treatment: The period before and after the fall of autumn leaves the green shoots spit green This period is called the dormancy period of fruit trees. This period is also the most vulnerable period of the vitality of diseases and insect pests, and it is also the critical period for the clearing of fruit trees. Scrap cure rot disease: The whole garden was inspected. The lesions found were completely scraped with a knife. Scratch to reach deep into the xylem, scrape to the edge of the disease plaque 0.5 to 1 cm of health tree, and then smear with rotten enemy raw drug. Because of the excellent film forming properties of the rotten enemy pesticides, and the fact that they contain phytochemicals that are easily penetrated into fruit trees, they not only kill pathogens, but also allow the bark tissue to heal quickly.

Seize the Opportunity to Do a Good Fruit Tree Clear Garden
Autumn and winter are the incubation period of all kinds of pests in fruit trees, which determines the degree of occurrence of diseases and pests in the coming year. Grasping this critical period, we must do a good job in the clearing of the gardens after the fruit trees are harvested and timely kill the wintering pests and germs of the fruit trees, which will have a multiplier effect for the orchard management in the coming year. Recently, the reporter interviewed Chen Ling, an expert in plant protection of Xi'an Dingsheng Bio-Chemical Co., Ltd., who was the appointed manufacturer of pollution-free pesticides in the Ministry of Chemical Industry.
