Tricyclazole, also known as clemenazole, clemenazole, biyan, and rice blastazole, is a selective systemic protection fungicide developed by Eli Lilly and Company of the United States. The patent number is BP1419121. It is a protective triazole fungicide with strong absorption performance. It has special effects in preventing and treating rice blast. After application, it can be absorbed by the roots, stems and leaves of rice, and can be transported in the plant. Spray 1~ Two doses of medicine can effectively prevent the occurrence of rice blast. Tricyclazole has strong anti-scouring ability, and it does not need to be re-sprayed in case of rain after 1 hour of spraying. It mainly inhibits spore germination and episporium formation, thereby effectively preventing the invasion of pathogens and reducing the production of spores of Magnaporthe grisea. Tricyclazole has strong systemic and transport properties, and it decomposes slowly in the plant body and soil, with a residual effect period of 7 to 10 weeks. It can be used as seed dressing, dipped in seedling roots or sprayed on leaves, and has a good preventive effect.

Features of Tricyclazole

Tricyclazole is a fungicide, which is specially used to prevent and control rice blast at various growth stages, and has certain toxicity to humans and fish. The bactericidal mechanism is mainly to inhibit the formation of episporium melanin, thereby inhibiting spore germination and epispora formation, preventing the invasion of pathogens and reducing the production of spores of blast fungus.

The pure product of tricyclazole is a white crystal with strong systemic property, which can be quickly absorbed by the roots, stems and leaves of rice, and transported to all parts of the rice plant. Generally, the absorbed drug amount in the rice plant can reach saturation within 2 hours after spraying. Its products mainly include 20% and 75% WP. It is mainly used for the prevention and protection of rice blast, and it is generally used before the onset of rice, and the effect of use at this time is the best.

Applications of Tricyclazole

There are generally two methods of using tricyclazole, which are seedling soaking method and spraying method.

Tricyclazole is mainly used for prevention and protection, and the effect is best when used before the onset of disease. The specific operation of the spray method is: to prevent and control seedling blast, at the 3-4 leaf stage of the seedlings or 5 days before transplanting, use 50-75 grams of 20% wettable powder per mu, spray on water; prevent and control leaf blast and panicle blast, At the initial onset of leaf blast or from the end of booting to the beginning of earing, spray 75-100 grams of 20% wettable powder on water per mu; when the panicle blast is severe, spray again at intervals of 10-14 days.

The effect of soaking seedlings with tricyclazole to prevent and control leaf blast is better than spraying before pulling out seedlings. The specific method of soaking seedlings is: put 20% tricyclazole wettable powder 750 times liquid into a bucket, or dig a hole at the edge of the seedling field. Shallow pits, covered with plastic film, filled with liquid medicine, tied up the uprooted seedlings into handles, slightly shaken the water, soaked in the liquid medicine for about 1 minute, removed, piled up for 0.5 hours and then planted.
