First, deal with gray mold Preferred methods: Solanaceous vegetables can be controlled by spraying with pyrimidine cyclic amine (and Swiss) and Shijiale (pyrimidine) 1000 times solution. Melon vegetables can be controlled by fluoxetine (DuPont's future) or niacinamide (Kaiser) 800 times on the basis of fludioxonil. Because old pesticides such as procymidone, iprodione, and ethidium bromide, which control gray mold, have been used for many years, their drug resistance has increased significantly. With its control of gray mold, even if the amount of use, the effect is not satisfactory. Especially after the outbreak of gray mold, it must be replaced with new ingredients for prevention and treatment, it is recommended to use environmentally friendly green biological pesticides. The low-temperature and high-humidity environment in the shelter is the main reason for the outbreak and epidemic of gray mold. Therefore, in management, we must first do a reasonable watering, timely ventilation, reduce the humidity within the greenhouse. Botrytis cinerea is easily infested by the open flower cultivar, so the prevention of botrytis must first be prevented from infestation. Pick up the fruits of the fruit in time and clean out the shed. The pathogenic spores of Botrytis cinerea are large and can be smoked and sprayed under the condition that spray prevention is difficult and thorough. Flue-cured smoke can be used to clean the net, but pay attention to the amount of use and smoking time, especially on beans and eggplant. Melons, tomatoes, and peppers can be used in 200 mu of mu (667 square meters) and 8-10 hours in smoke; 200 mu of beans (667 square meters) in beans and eggplant, and 6-8 hours in smoke. Second, deal with vegetables dead tree The preferred method: spicy (sweet) pepper can be used Pulike 1 package (10 g / bag) plus Jin Lei 35 grams Jia Fu Xing 1 package (2 g / bag) 30 pounds of water to irrigate root; cucumber available difenoconazole (world High) 1,000 times liquid mixed with fludioxonil (Cola) 1500 times Irrigation root. Phytophthora root rot is the most common cause of death in hot pepper trees, but behind the poor control results of using Preco Plus DT (copper ferric copper phosphate) or metalaxyl plus hymexazol, etc. First of all, it should be noticed that the drug is not symptomatic, and it is very likely that the drug resistance of the bacteria has increased. In this regard, the selection of two pesticides for the treatment of disease and the re-mixing of Fuxing can serve the purpose of enhancing the efficacy of the disease and simultaneously treating various diseases such as root rot of Pythium. Spicy (sweet) Phytophthora root rot, the main damage spicy (sweet) pepper stem base, was initially hot water-like, after the "black stalk." The disease has developed rapidly. In the case of controlling the humidity in the field, it is also promptly checked and promptly prevented and controlled. At the same time, it is also one of the reasons for the use of two agents for prevention and control. The main diseases that cause grafted cucumber to die are: Phytophthora root rot in rhizomes: At the onset of disease, the leaves of the plants appear wilting during the day and recover at night or on cloudy days. After a few days, the lower leaves begin to yellow and gradually develop upwards, leading to the development of melon strips on the plants. bad. The common symptoms in the shed are: When grafted seedlings use black-skinned squash, the base of the stem near the ground is immersed in brownish rot, causing the plants to die. The roots of the stems did not show signs of flooding and rot, and the vascular bundles of the plants did not turn brown. However, the roots of the roots were found to be brown and decayed, and part of the main roots and lateral roots turned light brown. In severe cases, the roots turned brown or Dark brown. Mare diseases above marrying interfaces: Blast disease infects cucumber leaves and invades from the leaf margin, resulting in "V"-shaped large lesions, pale brown, later lesions easily broken, dense black spots on the lesions. When the petiole, melon vine, or base of the stem is damaged, the lesion is oily, oval to spindle, yellow-brown, sometimes overflowing with an amber jelly. When the disease is severe, the vines are white and dry, rot, and broken. Blast disease develops from the surface of the stem to the interior. In the late stage of the disease, the longitudinal base of common stems is chaotic and shrinking. The disease is also the main cause of bad heads in cucumbers. Difenoconazole (Shigao) 1000 times liquid plus fibrionitrile 1500 times Irrigation rooting to prevent the spread of the premise, the use of chlorothalonil, amoeba and other agents spray or smear for prevention and treatment.
