Application of Spore Capture Device in Control of Apple Alternaria Leaf Spot Disease

There are many important apple producing areas in China. The apples produced in these areas are of good quality and good taste, and are deeply loved by consumers. However, in the process of apple production, apple spotted leaf disease is harmful to the growth of apple trees. Through analysis, it can be known that the occurrence of apple leaf spotted leaf disease is not only related to the quality of seedlings itself, but also an important factor is the apple orchard. The spores caused by the disease, so to prevent the occurrence of apple leaf spot defoliation, the harm of this apple disease to a minimum, we should also use the spore catcher to do a good job in forecasting and carry out scientific and effective disease prevention.

In general, there are four methods for the prevention and control of apple leaf spot defoliation. The first is strict recommendations, as far as possible from the ward to introduce seedlings and scion. The second is to strictly clean the garden. In autumn and winter, the fallen leaves are carefully removed, the diseased branches are cut off, and the burning is concentrated. The third is the use of spore capture instrument for the capture of orchard spores, do a good job of forecasting, after the capture of the spore capture device, the technician will take the slide to check the microscope, when the first spot is found, that should fight drug control . The fourth is the chemical control. Generally speaking, spore traps are used to monitor the spores in the field. Therefore, when the pesticides are controlled, they will be more targeted. The types and dosages of the drugs will be more scientific, and the control effect will be even better. Well, it can effectively reduce Apple's pesticide residues.
In short, the prevention and treatment of apple leaf spot defoliation should implement the principle of “prevention-oriented, comprehensive treatment”. Therefore, in combination with the application of spore capture instrument, it can meet the requirements of modern green plant protection and conduct work in a healthier and more efficient form of plant protection. Depending on local conditions, we should rationally use chemical pesticides, biological control, and physical control measures to economically, safely, and effectively control pests and diseases so as to achieve the purpose of improving production and quality and protecting the environment and people's health.
