Occurrence and Control of Watermelon Diseases and Insect Pests in Summer High Temperature Season

First, the disease part 1. Powdery mildew: The disease in the high temperature and drought alternating with the high temperature and humidity climate is particularly prone to occur, especially in greenhouse cultivation is more serious. Continuous high-temperature drought or continuous rainy days have certain inhibitory effects on the development of powdery mildew. Prevention and treatment of the disease should focus on the following four aspects: 1) Strengthen field monitoring, detect diseases as soon as possible, and conduct selective and selective chemical control at the initial stage of the disease; 2) Remove diseased tissue in the field at the initial stage of disease, and Do a good job of field isolation work to reduce the spread and spread of powdery mildew; 3) Strengthen the management of fertilizer and water in the whole garden, and use high-efficiency foliar fertilizer such as “Cui Kang Shengli Liquid” to increase the disease resistance of the plant; 4) Chemicals are continuously applied 2-3 times to the entire garden. Therapeutic agents can use 50% Tribeca 3000 times or 25% Burley 3000 times or 43% Holoca 5000 times and other agents; prevention before the onset or early onset can be used 80% of the standard 600 times or 2% "agricultural resistance 120" 200 times spray. 2. Anthracnose: The climatic conditions of high temperature and high humidity are extremely suitable for diseases. In our country, the disease gradually increases from the beginning of June. To prevent and treat this disease, we must first strengthen ventilation management to reduce the humidity in the shed, reduce the amount of nitrogen fertilizer application and other field management; timely spraying control, in the early stage of disease can use 50% Poly 2500-3000 times or 25% torch 1500 times before the onset Choose 68.75% Yibao 1000 times or 70% product Run 600 times. 3. Sclerotinia: In low-lying areas, poor drainage, dense planting, and partial application of nitrogen fertilizers are prone to occur, whereas high-temperature and drought conditions do not occur easily. When field strains are found, they can be sprayed on the plants and the surface with agents such as 50% Propane Suspension 1000 times or 20% Propofol Suspension 500X or 50% Ash Net 1000X. Medication. Second, the pest part: 1. Starscream (Melon Leafhopper): Red spider is a kind of hi-temperature and low humidity pests. In March-April, we usually feed on weeds or other hosts. In the first half of May, we began to move into the danger of melon fields. In June, the breeding rate began to increase, and the number rose to the end of June. The damage was most serious. Control agents can be used: 50% Torque 3000-4000 times or 20% of fruit 1500 times special or 1% of insects killing 1500 times and other spray. 2. (Melon) Thrips: Adults can fly well, but they can also spread by wind. At the same time, their reproduction speed is very fast, so they are prone to disasters. The climate conditions of high temperature and low humidity are particularly suitable for their damage. The quail horses tend to be tender and tend to focus on the backs and tenders. Pharmacy control options: 5% Ruigente suspension 2000 times or 70% Yimeile, 10000 times or 20% good year of winter 600 times or 20% thiomethoxacin 5,000 times or 20% Bixi 4000 times, etc. Use, spray 2-3 times continuously. 3. Gualou: This pest is generally occurring intermittently in the hot season. It mainly damages melons and melons of melons (such as watermelons and loofahs), commonly known as "plankton." The larva body has two distinct white dorsal lines on its back. Chemical control uses 5% Flytrand 1000-1500 times for even and thorough spray, which has excellent control effect. 4. Nocturnal insect pests (Spodoptera exigua, Spodoptera litura): The most effective agents for the control of nocturnal insect pests are mainly stomach poisons, so the spray must be thorough, the amount of water spray should be sufficient, and medication should be used in younger ages. The control agent can choose 15% of the hits 4000 times or 24% of the 2000 times or 20% of the dead insects net 800 times, etc., and mixed with Wan Ling or Fu Rui and other agents can play a very good ovicidal effect.

Cardiovascular disease is a serious threat to human, It is a common healthy disease especially in the elderly over the age of 50, even if used the most advanced treatment, there is still have more than 50% of cerebrovascular accident survivors can not completely self-care, The world's annual deaths from the disease as high as 15 million people, ranking the first cause of death. Cardiovascular disease is the number one disease that threatens human health. Currently Anti-Cardiovascular disease drugs mainly include cardiac drugs, anti-angina drugs anti-heart rate disorders drugs, antihypertensive drugs, anti-hyperlipoproteinemia drugs. Drug therapy is only a means of prevention, The fundamental is prevent from the source. Cardiovascular disease, in addition to being affected by genetic factors, mainly is associated with unhealthy lifestyles. Also known as lifestyle sickness. So the establishment of a healthy and reasonable way of life is the key to prevention.
