Diseases and pests that need to be controlled during soybean flowering
Recently, most of the soybeans in Tongzhou District of Nantong City have entered the flowering stage. The pests in the field include soybean cakes, soybean leaf files, soybean tussock moths, snails, etc. Some of the fields of downy mildew disease are serious and need timely prevention and treatment. Four fourth-generation bean pods from soybean meal usually occur from mid-August to early September, and larvae feed on the pods. The optimum temperature for the growth of soybean meal is 30~32°C. The current temperature is consistent with it, which is very favorable for the occurrence of soybean meal. According to the observation under the lamp, the amount of moths has continued to rise in the near future, and it is expected that the egg hatching period will occur in late August and that the degree of occurrence will be moderate. Partial occurrences will occur. Especially in late August, the soybeans that are in the pupal stage will be more seriously harmed. Soybean leafhoppers use larvae to damage the leaves and cause leaf curling. The larvae hide inside the leaflets and feed on the leaf. According to a survey conducted on August 15th, the planting rate of soybean field in the soybean field was 0-40% with an average of 20.5%, and 100 strains of insects amounted to 0-30 heads with an average of 15 heads. The imbalance between fields was large. The occurrence of soybean tussock moths is widespread and local plots are heavier. The nested larvae clustered on the back of soybean leaves and soon dispersed. After the plants were killed, only the reticular veins remained. In severe cases, a "light pole" was formed. The third generation of eggs began to appear in early August of this year, and the larvae were endangered in the middle and late August. Snails and snails feed on stems, leaves, buds and fruits to cause cavities and nicks. In severe cases, the leaves are used to cause dead seedlings. Snails like to inhabit the ditch and wetlands are heavy. The downy mildew disease mainly damages the leaves. From the first true leaf, a round brownish green patch is produced along the leaf veins at the base of the leaves. The leaves have yellow spots on the front. There are gray moldy layers on the back of the leaves. Many lesions are formed when the disease is severe. Large patches, easy to dry and leave the leaves. At present, 40% of the diseased fields occur, and the diseased plant rate is 0-25%. The degree of occurrence is moderate, and local occurrence occurs. At present, the prevention and control of pests and diseases in soybean fields is focused on soybean meal, treating both downy mildew disease, inspection and treatment of soybean leafrollers, soybean moths and snails. Controlling the use of soybeans at the end of the flowering period to the early stage of scab, with 44% chlorobromothromphosin EC 80 to 100 ml per acre, plus 50~60 kg of water spray, and the downy mildew occurring in heavy plots plus 75% of chlorothalonil per mu. Clear WP 120~130g. The spray should be even and thoughtful, the amount of liquid should be no more than a drop of moisture, spray sooner or later, and prevent it once every 7 days. To control snails in soybean fields, use 6% acetaldehyde granules 0.5-0.6 kg per mu, and mix 10-15 kg of dry fine soil for application. Clear Sterile Vials are primarily used for mixing different medications or solutions for injection or research applications like HCG, heparin, lidocaine, diabetic medications and morphine for intravenous or syringe injections. Some drugs may need to be diluted or mixed with sterile water or other drugs. Sterile Vials are also used for nuclear medicine, PET-CT, Liquid collection. Clear sterile vials are also used for nuclear medicine, PET-CT, Liquid collection.Clear sterile vials are produced by aluminum caps, non-latex butyl stoppers and clear SCHOTT Neutral Type I glass vials. They are approved by cGMP and FDA with internally sterile.The production process is carried out under strict Class 100 workshop. Finished vials can meet the FDA`s authorised 14-day sterility test.
