30% Aimiao EC has a good effect on rice.

Rice sheath blight, rice grain smut, rice false smut, brown sheath rot and other diseases often occur in rice, which have the characteristics of outbreak and epidemic, which will lead to serious loss of rice yield, affecting both yield and quality. There are many agents used to control the above rice diseases in production, but according to our experiments, the application of 30% Aimiao EC on rice can not only ensure the effect of disease control, but also increase rice yield and improve rice quality.

Good disease control effect 30% Aimiao EC is made from propiconazole and difenoconazole, which has a good control effect on diseases caused by fungi such as cystic bacteria, basidiomycetes and difenoconazole, and has a high efficiency and broad spectrum internal absorption fungicide. 30% Aimiao EC has a strong inhibitory effect on spore formation of plant pathogens, and can inhibit conidia maturation and germination, so as to control the further development of the disease. 30% Aimiao EC has strong permeability and adhesion, is resistant to Rain Water erosion, and is suitable for use in the rainy season (rice diseases in the middle and later stages often occur in rainy seasons). Generally, rain 2 hours after application will not affect the control effect, and the effect is longer. The propiconazole in 30% Aimiao EC can be quickly absorbed by the stems and leaves of the plant within 2 hours after application, and transmitted upward through the transport tissue in the plant, which can effectively control the spread of the disease spot, while difenoconazole has a slower conduction velocity and a longer duration of effect. the effective protection period is 20 ~ 35 days. In 2005, experiments in various parts of Hunan Province showed that the control effect of 30% Aimiao EC on rice sheath blight reached 95%, which was better than that of Jinggangmycin, and the control effect of rice smut was significantly higher than that of triadimefon. The control effect of rice false smut was also significantly higher than that of Jinggangmycin and triadimefon.

two。 The application of 30% Aimiao EC on rice can obviously regulate the growth of rice and increase the yield of rice. Its main mechanism is that it can inhibit the biosynthesis of gibberellin in rice and reduce the content of indole acetic acid. The grain filling of inferior grains of rice is mainly regulated by indole acetic acid. Spraying 30% Aimiao EC can inhibit the effect of strong grains on the grain filling of inferior grains, and make the final grain weight of inferior grains closer to that of strong grains, and has no significant effect on strong grains. According to the experiment, the application of 30% Aimiao EC to rice can increase the rice yield by 7.5% to 20.2% compared with the application of conventional chemicals: the seed production yield of rice seed production can be increased by 12.8%.

3. Using the method to control rice sheath blight can be applied at the initial stage of the disease, using 15 milliliters of 30% Aimiao EC for every 667 square meters of rice fields, and spraying evenly no less than 30 kilograms of water. The medicine was applied for the second time after 10 days. The control of rice grain smut and false smut can be applied once 5-7 days before rice break heading and at full heading stage, with 15 ml of 30% Aimiao EC for every 667 square meters of rice field, not less than 30 kg of water, and evenly sprayed. In rice seed production, the use of 30% Aimiao EC will not affect the seed setting rate because of the damage to the maternal stigma during flowering, so it is suitable for large-scale application in rice seed production area to control rice grain smut.
