Shouguang Yang, Manager of Shandong, via SMS (136****7769) April 2 Q: In the past two years, cucumbers have been planted. Diseases are very common. How can we effectively control common cucumber diseases?
Jia Youjiang, Agricultural Bureau of Rucheng County, Shandong Province, China. Answering the common diseases of cucumber can be done in four steps. The first step is to determine if the cucumber is onset. First of all, from the abnormal appearance of the plant, we can judge the disease from the external symptoms of the plant or the symptoms of the fruit, and also confirm whether the disease is a physiological disease or an infectious disease. The characteristics of general physiological diseases are that the area is large and the time of onset is the same, but it is not contagious. Infectious diseases are characterized by the onset of individual plants.
For physiological diseases, by changing the unfavorable environment of the plant growth, adding a harvest number 800 solution at the time of spraying can enhance plant resistance and enhance the plant's resistance to adverse environments.
For the prevention and control of infectious diseases, we must first eliminate the seed pathogens. We can use warm hot soaking or chemical seed dressing to eliminate bacteria. The common methods are: 1. Soaking in warm water: soak the seeds in warm water of 55°C for 25 minutes, then Cool with cold water and allow to dry. 2. Seed soaking with chemicals: Soaking seeds with 100% formalin for 100 minutes, soaking seeds for 30 minutes, washing with water after soaking, and air-drying; seeds can also be soaked in 2-3% bleach solution for 30-60 minutes. After immersion, wash with water; also use thiophanate-methyl 800 times solution soaking for 4 hours. 3. Chemical seed dressing: Use 50% thiram WP, seed dressing at a seed weight of 0.4%.
The second step is to confirm what is the cause of the illness. When it comes to the cause of morbidity, we must start with the growth environment of cucumbers. Cucumber plants in greenhouses are generally wintered in seeds, soil, or manure and become the source of infection in the next year. Most diseases of cucumber need to be more than 85% of relative humidity. Therefore, one of the main reasons for the serious diseases of cucumber is excessive humidity.
The third step is targeted prevention and control. To prevent and control diseases, we must first create an environment suitable for the growth of cucumber that is not conducive to the growth of germs, that is, control the temperature of the greenhouse and reduce the humidity. After the onset of drug use to prevent disease, downy mildew and epidemic disease drugs are basically the same, commonly used agents such as mancozeb zinc, preclinical and metalaxyl manganese zinc and other agents. The commonly used fungicides for gray mold include sclerotium, Shijiale, and acetaminophen. The commonly used agents for bacterial plaques include streptomycin and DT.
The fourth step is to take care of the following matters during the prevention and control: 1. Distinguish whether the bactericidal agent is protective or systemic. The protective agent should be played early. The spraying should be thorough and meticulous. The systemic drug can be used after the onset of disease. 2. The main prevention is prevention and control, and spraying should be based on the word "defense." 3 to mix medication, alternating medication, in order to improve the control effect and prevent drug resistance. 4. To improve the quality of spraying, the back of the blade should be evenly and carefully sprayed, grasp the main contradiction, and spray the key parts according to the characteristics of the disease.
