Under normal weather conditions, in the initial stage of rice breakage, the compounds with strong systemic absorption and long duration of action, such as tetracyclzolium, rice bran amide, pyraclostrobin, etc., are used to prevent and treat once, and usually have good control effect on panicle blasts. . Comprehensive consideration of weather, artificial factors, etc., can also be combined with the prevention and treatment of false smut, the first time to use drugs to advance before the rice break 5 to 7 days; depending on the weather and other conditions, in the full heading period to consolidate the control effect; if the rice The heading stage is particularly suitable for high-humidity and rainy weather where the head and neck ridge occurs. Tricyclazole has only a protective effect and is best used in the front. Benzocilazole has a certain control effect on the panicle cervix, but its efficacy is not stable. It is not appropriate to use this drug alone to prevent panicle cervix. In addition to focusing on the head and neck ridges, the "breaking medicine" of rice usually has to use suitable herbs to prevent and control rice planthoppers, rice leaf roller, and aphid pests, as well as proper treatment of rice smut and sheath blight. The use of chlorantraniliprole, tetrachamuspide, indoxacarb, fluorobenzamide, avermectin, emamectin benzoate, and their blends to control rice leaf roller , Aphids, the use of nitenpyram, flumethrazepam, pymetrozine and other drugs to control rice planthoppers, the appropriate use of hexaconazole, benzocyclopropazole and other drugs cure rice false smut, sheath blight.

After the panicle differentiation of rice is completed, the ear begins to protrude from the last blade, the leaf sheath of the flag leaf, exposing the grain, called the break. In the early stage of rice breakage, it is a critical period for the use of drugs to prevent panicle blast. Some rice plants in the field can apply pesticides when they break, and the time for drug use is delayed, and the effectiveness of panicle rot control is reduced. If rice has continuous rainy weather during heading, it is necessary to grab the pesticide before the rain, or to catch the rain and stop the application of pesticides, so as not to miss the effects of control measures.
