The locust picking and treatment of seedlings and cultivars are the two main stages for the seedling blast and the panicle blast, and the strategy of “selecting and treating seedling lice and indicating panicle blast†should be adopted. When the amount of 100 strains in the field reaches 500 and the hazard ratio is greater than 1:500, use 50 ml of 25% nicotine per acre, or 1500 to 2000 times spray of imidacloprid, and 10% of net 60 70 grams; 20% of imidacloprid 2500 times; 25% of anti-influx 3000 times spray control. Wheat buckwheat is resistant to imidacloprid and acetamiprid resistant to wheat, and should not be used as a single agent. It can be reasonably mixed with low-toxic organophosphorus pesticides.
Prevention of head scab disease mainly took the initiative to attack the prevention and control strategy, and grasped the proper period of prevention and control of wheat heading and flowering, and implemented the “Yanghua a piece, a piece of prevention and control, and comprehensive drug controlâ€. When the heading is at high temperature and fine weather, the heading and flowering will be carried out. If the weather forecast has continuous rain, it is necessary to seize the heading stage; if there is less sunshine at the heading stage and the wheat first blooms after heading, it will be at the flowering stage (5% to 10%). Plant flowering) medication. After application, in case of rainy weather, it is necessary to use a second medicine every 5 to 7 days in order to improve the control effect. Most wheat areas can be treated with 50% carbendazim WP 100 g/mu or 70% thiophanate-methyl disperse 70 to 100 g/mu. For the bacteria has already produced resistance, it is recommended to use tebuconazole, prochloraz, cyanocaverate and other agents mixed with carbendazim or in rotation.
Stripe rust RBI district governance is currently focused on doing a good job of early pharmacy prevention and control, on the incidence of key fields to take drug investigation, found that one point of control, and timely control of the epidemiological center; to provide wheat field defense rule to control the spread of disease spread. In spring-endemic areas such as Huang-Huai-Hai, it is necessary to strengthen the monitoring of disease conditions and implement spraying control when the standards are met (the diseased leaf rate reaches 5%). Promote the use of triazoles and dinazoles as high-efficiency, low-toxic, inhalation fungicides to control field sprays. Use 15% triadimefone powder 80 to 100 grams per acre, or use 25% fennelizole powder 30 tons per acre. ~ 40 grams, or 12.5% ​​suspension spray 40 ml control, control effectiveness of up to 90%.
Orange has a fragrant shampoo having stable paste consistency suitable, white color, lasting aroma characteristics, have a good effect hair care and hair fixed.
Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
