The currently-planted autumn-delayed cucumbers and bitter gourds are all climbing plants of the cucurbitaceae. Their living habits are similar, and the characteristics of plant management techniques are roughly similar. Now it is simply listed on its current prone diseases and prevention measures for the reference of farmers.

First, downy mildew, gray mold, and bacterial plaque are collectively referred to as the “three major diseases.” Under normal circumstances, downy mildew and bacterial diseases are easily mixed, which brings many difficulties to prevention and control. Therefore, prevention must be effective when it involves multiple measures. Common control agents include: mancozeb zinc, ene morpholine, cymoxan manganese zinc, metalaxyl MnZn, while adding Yeetzolium, mesitectin, copper rosin, etc., timely supplement medicine, with Increase its disease resistance.

Second, powdery mildew is currently common, with the continuous growth of cucumber, bitter gourd and the weather and temperature and humidity are more and more suitable for the occurrence of the disease, but also to strengthen prevention and treatment. In severe cases, when the white powder covers the entire leaf, it can greatly affect the photosynthesis and make the crop premature. The yield and quality of the melon strips are greatly reduced. Prevention is the main method. After easing the seedlings, the chlorothalonil and carbendazim or arbuterol are sprayed for protection. The effect is good. After the occurrence of prevention and control, removal of diseased leaves, strengthening the shed ventilation and light, continuous control 2-3 times.

Third, anthrax disease The disease is also a cucumber, bitter gourd susceptible to disease, one of the serious, so that the melon strip covered with black spots on the surface, affecting the value of their goods and reduce economic benefits. Drugs can use myclobutanil, bromobaclofen and so on. Mainly preventive protection.

IV. Viral Disease This year, the nationwide pandemic of the virus, once there is no cure, the virus can infect more than 20 kinds of vegetable crops, especially tomatoes, followed by zucchini, and then bitter gourd, cucumber, etc., beans are also compared In general, prevention must be prepared. The early bitter gourds grown in the Qingzhou region of Shandong have almost no production. The pesticides used in the prevention and treatment of agricultural products include streptomycin sulfate, morpholinium copper, and Ningnanmycin. Due to the changing weather this year, it has brought many difficulties for prevention and control work. About half of the tomato sheds in Shouguang, Shandong Province have been planted or replanted with other vegetables due to the virus, and some have even become idle to avoid the high-risk virus and suffered heavy losses. The Formulation of “Huanghua Leaf Curve Virus + Raw Liquid + Gengfeng Zinc” introduced by Shandong Dadi Honglin Agribusiness Company is an ideal control agent selected after various agents are tested separately, and has the effect of controlling the rapid development of the virus. .

V. Bacterial spot can be used for special effects "Triumph."

Six, leaf blight This disease is a bacterial disease, control can refer to downy mildew. The specific drug is "Triumphal."

VII. A new spotted "target spot" discovered by brown spot disease. The symptoms of the disease are the same as those of brown spots. However, it is difficult to cure. A special drug "name board" can be used with good results.

    A urine analyser is a device used in the clinical setting to perform automatic urine testing. The units can detect and quantify a number of analytes including bilirubin, protein, glucose and red blood cells. Many models contain urine strip readers, a type of reflectance photometer that can process several hundred strips per hour.
