core In dryland, many seedlings are found to be slightly taller than ordinary seedlings, and their stems and leaves are slender, with yellowish seedlings. When they reach the jointing and booting stage, these seedlings grow earlier and longer than common seedlings, and the stems are taller. There are few tillers, or basically no tillers. Farmers habitually pull out the fields, but the effect is not good. There will be such seedlings. what happened? The appearance of these symptoms is mainly caused by the large amount of gibberellin secreted by the bacillus in the growth and reproduction of the diseased plant. Rice bakanae disease is a fungal disease. Seed bacteria are the main primary infestation source of bastard disease, followed by rice straw. Rice bastard disease can be cured once it is manifested in the field. Therefore, seed treatment is the most economical and effective measure for preventing and treating the disease. It mainly includes medicinal soaking and coating treatment. Seed soaking. The soaking agent has a strong chlorohydrin WP: According to the test, the rice soaking is disinfected for 1 day by using a strong chlorine fine liquid with a ratio of 500 times, and then the seed residual liquid is washed with water, and soaking and germination according to the conventional method. The effect of preventing bakanae disease in rice fields is 97.9%, and the agent is cheap, effective and low toxic, and easy to use. 18% Rice Seed Cleaner WP: First, add 3 grams of powder to 7 kg of clear water and mix well. Then add 5 kg of rice into the liquid and stir it evenly. After soaking for 72 hours, collect the seeds and rinse with clean water. Then press Conventional operation germination. 25% to 100 grams of EC: 2 mL of medicament plus 6-7 kg of water, about 5 kg of soaked rice, soaking for 48-72 hours, direct germination without water washing. There are many types of rice, and soaking the preparation liquid according to the above ratio. In addition, the agents that can be used for soaking seeds are: 25% cedronate suspension 2000-4000 times, or 25% prochloraz 2000-4000 times, or 17% ciclosporin wettable powder 2000- 4000 times liquid and so on. When soaking with pesticides, care must be taken to ensure that the concentration of the liquid is not increased blindly, and that it does not want to be reduced. Ensure that soaking time is 48-60 hours, do not use panning after soaking, direct sowing or germination sowing; Second, pay attention to uniform soak; It is to prevent the whole bag of rice seed from being soaked in the container. When the rice is sowed in batches, it cannot be reused when it is soaked in batches so as to prevent the concentration of the liquid medicine from being reduced and the contamination of pathogens and to reduce the control effect. Fourthly, the seed soaked can be sowed without germination. More dip less urge, in order to reduce the infection of long bud stage bacteria. Coating treatment. Currently used 0.25% tebuconazole suspension seed coating agent and 25% prochloraz EC. The 0.25% tebuconazole suspension seed coating agent was diluted with 75 ml, 100 ml, and 125 ml water to 170 ml coated rice seeds for each 5 kg rice seed. The method is to take a small plastic bucket with a lid, add the rice seeds into the bucket, dilute and mix the corresponding amount of seed coating agent, and pour it on the rice seed. Cover the plastic cover and quickly rotate the plastic barrel clockwise for 10-15 minutes to fully turn the rice seeds until a uniform layer of red drug film is uniformly coated on each seed. Pour the bag and dry it for 3 days. Soak after curing. 25% Prochloraz EC is soaked in 4000 times solution.
