Tricyclazole, with the CAS number 41814 - 78 - 2, is a well - known fungicide in the agricultural industry. It is offered by our factory at a very competitive price. The chemical formula of Tricyclazole is C₉H₇N₃S, and its molecular weight is approximately 189.24 g/mol. Physically, it appears as a white to light yellow crystalline solid with a melting point of around 187 - 188°C. It has low solubility in water but is soluble in some organic solvents like acetone, chloroform, and methanol. The product is typically available in various formulations, such as wettable powders and emulsifiable concentrates, to meet different application needs.
Tricyclazole is mainly used as a preventive fungicide to control rice blast disease, which is one of the most devastating diseases affecting rice crops worldwide. Rice blast, caused by the fungus Magnaporthe oryzae, can lead to significant yield losses if not properly managed. Tricyclazole works by inhibiting melanin biosynthesis in the fungus, which is essential for the penetration of the fungus into the rice plant tissue. By preventing the fungus from entering the plant, it effectively protects the rice plants from infection. Besides rice, it can also be used to control certain fungal diseases in other crops in some cases, although its primary application is in rice production.
When using Tricyclazole, it is crucial to follow the correct application methods and dosages. For wettable powder formulations, the general recommended dosage is usually between 25 - 50 grams per 100 square meters, depending on the severity of the disease and the growth stage of the rice. It should be diluted with an appropriate amount of water according to the product label instructions. The diluted solution should be sprayed evenly on the rice plants using a suitable sprayer. It is advisable to apply Tricyclazole before the onset of the disease or at the early stage of infection for the best results. Applications should be repeated at regular intervals, typically every 7 - 10 days, to ensure continuous protection throughout the growing season. When handling the product, wear appropriate protective clothing, gloves, and a mask to avoid direct contact and inhalation.
In a large - scale rice farm in Southeast Asia, the farmers were facing severe problems with rice blast disease. Before using Tricyclazole, the yield losses were estimated to be around 30% due to the disease. After implementing a preventive spray program with Tricyclazole starting from the early tillering stage of the rice plants, the situation improved significantly. The incidence of rice blast was reduced by more than 80%. The farmers observed that the rice plants were healthier, with fewer lesions on the leaves and panicles. As a result, the final yield increased by approximately 25% compared to the previous year without Tricyclazole application. Another case study in a small - scale organic rice farm in South America showed similar positive results. Even though the farm had limited resources, by using Tricyclazole in a timely and proper manner, they were able to control the rice blast and maintain a stable yield, which was crucial for the economic viability of the farm.
