In the case of rice heading in continuous low temperature and rainy weather, the rice should be controlled by universal drugs. For the susceptible varieties, it should be during the break period (wide field rice break 10%-15%) and full heading period (80% of the whole field rice heads Take out), twice medication control. Applicable agents are rice bran, tricyclazole, prochloraz and the like. Among them, rice bran, tricyclazole, and other drugs have extremely strong internal absorption conductance. Generally, there is no rain for 2-3 hours after application, and the control effect can be guaranteed. From the weather forecast, the weather in recent days is mostly thunderstorms, and it can be sprayed according to the situation. When there is water on the rice leaves after the rain, it is advisable to appropriately reduce the amount of water, fine spray or spraying with a mist sprayer. In this way, high-concentration liquid medicine falls on rice leaf with water, and can be diluted twice, evenly distributed to the leaf surface, avoiding large quantities of liquid medicine from falling off the leaf surface and affecting the control effect. To control rice smut, it should generally be applied about 1 week before the rice break. According to experiments conducted by the Jiangsu Academy of Agricultural Sciences and other units many years ago, Jinggangmycin was used to control rice smut, and the effect of spraying was best about 1 week before the rice break, and then the pesticide was applied again at the time of breaking. There was almost no control effect. From the perspective of trial demonstration and large-scale production and drug use in recent years, it is applicable to the prevention and treatment of benzoylcyproconazole, tebuconazole and other azole fungicides, copper noble basic copper sulphate, copper hop acid copper copper and other copper Medicaments such as preparations and prochloraz are used in the heading stage of rice and have a certain control effect on rice smut. One week before rice breakage, there was no field for the control of rice smut disease, and the above-mentioned agents could be selected to prevent and control rice smut disease at the heading stage. The azole fungicide is used excessively at the heading stage of rice, especially when the growth of rice is inhibited under low temperature and rainy conditions. It may affect rice heading and grouting. When applying pesticides, it should be strictly controlled and dosage should not be increased blindly. Prochloraz and copper noble basic copper sulphate have good control effects on rice glutinous rice disease and rice blast disease. The normal use of rice has a low risk of phytotoxicity, and rice can be used preferentially at the heading stage, or with Other agents are mixed or used interchangeably.
