Because the majority of vegetable farmers lack the correct knowledge of drugs and medications, there are five types of deficiencies that need to be noted in scientific, rational, and efficient drug use. The first category: blind agricultural pesticides are not applied to the occurrence and development of diseases and pests, but based on many years of experience. For various diseases of vegetables and vegetables, whether they are fungal diseases, bacterial or viral diseases, see the leaves of vegetables. The fruit is sprayed with a slight change; for all kinds of insects, whether caused by aphids or mites, see pests. In fact, each pest has its own unique habits and hazards. For example, powdery mildew is easy to infect the young part of the vegetables, and black spot disease is easy to infect from the lower leaves. Ascarids and mites are concentrated on the back of the vegetables. , absorb vegetable juices. Most of the pesticides used to prevent and treat diseases and pests are particularly strong in specificity, and they often target diseases caused by one or a certain type of pathogen and are ineffective against other diseases. Therefore, it must be applied due to illness. The second type: Dosage type of many agricultural chemicals, not based on the use of drugs to scientifically and reasonably use the dose of pesticides, but on their own estimates, thereby increasing the dose. As pesticide dosages increase, the resistance of various pests and diseases increases. The pesticides with low toxicity and longer use time can no longer eliminate pests and diseases of the vegetables and destroy the ecological balance, causing pollution to the ecological environment, and even causing economic losses to vegetable production and damage. The third category: most of the climate-based vegetable farmers generally believe that when the weather is hot at noon, pesticides sprayed quickly, and the control effect is good. This will cause pesticide poisoning in the greenhouse due to the high density of vegetables in the greenhouse and poor ventilation. Therefore, it is best to avoid hot weather at noon and should be sprayed before 10 a.m. and after 4 p.m. The fourth category: Most hybrid farmers do not mix pesticides according to the nature and use of pesticides. Under certain conditions, the mixing of drugs is synergistic, but most vegetable farmers are blind to the mixture of pesticides. With antagonism, some pesticides sprayed on vegetables can produce phytotoxicity and reduce the yield and quality of vegetables. Pesticides should be used in combination with clear prevention and control targets to determine the best pharmaceuticals and formulas. When dispensing, follow the order of wettable adhesives, suspending agents, liquids, and emulsifiable concentrates, and add them in an orderly manner. Mixing pesticides should be used along with the mix, and should not be used for a long time. Store. The fifth category: Some insect-free vegetable farmers see pests in the shed, and they will immediately spray pesticides to completely eliminate them. In fact, it is completely unnecessary. Under normal circumstances, no more than a certain number of pests in the shed will not cause economic losses to the production of vegetables. Some insect pests are resistant to drugs, mainly due to irrational use of drugs and abuse of pesticides. China Agricultural Network Editor
Origin in Xinjiang, the largest origin of raisins in China. Raisins can contain up to 72% sugars by weight, most of which is fructose and glucose. They also contain about 3% protein and 3.7%–6.8% dietary fiber. Raisins like prunes and apricots are also high in certain antioxidants, but have a lower Vitamin C content than fresh grapes. Raisins are low in sodium and contain no cholesterol. Among individuals with mild increases in blood pressure, the routine consumption of raisins (three times a day) may significantly lower blood pressure, especially when compared to eating other common snacks.
