Recently, there have been many new developments in the field of chemical raw material fipronil, attracting attention from both inside and outside the industry, from project progress to product research and development.
In terms of project promotion, the 1500 tons/year fipronil project has completed the main construction, equipment installation, and commissioning work. After the trial production plan has been reviewed and approved by experts and filed with relevant regulatory authorities, it officially enters the trial production stage. As a third-generation nicotine insecticide, fipronil has contact and stomach toxicity characteristics, and is highly effective, long-lasting, and has a wide insecticidal spectrum. It can exhibit strong insecticidal activity at extremely low doses. It can not only effectively control aphids, leafhoppers, planthoppers, thrips, whiteflies and their resistant strains on crops such as wheat, rice, cotton, and vegetables, but also be equally efficient against pests of Coleoptera, Diptera, Lepidoptera, and Homoptera. It also performs outstandingly in the field of controlling sanitary pests such as cockroaches, fleas, and termites. The launch of this project will further enrich the supply of fipronil raw materials in the market and meet the growing demand in the agricultural and health sectors.
Through innovation and using arginine as a co solvent, a stable 10% fipronil soluble agent with physicochemical properties was successfully prepared using hydration solubilization technology. After testing, the product showed excellent rapid killing and sustained efficacy against German cockroaches after residual spraying. After 30 minutes of contact, the 72 hour mortality rate is ≥ 70%; After 45 days of storage, the 72 hour mortality rate is still ≥ 70%, which provides a new powerful weapon for the field of health pest control and has a very broad market prospect.
In addition, a company has successfully developed a 20% suspension of fipronil and indoxacarb. Researchers used wet grinding technology to carefully screen various components such as wetting agents, dispersants, thickeners, antifreeze agents, etc., and determined the optimal formula. The suspension agent has excellent physical stability and all indicators meet the testing requirements. Field experiments have shown that at a dosage of 120g a.i./hm ², the control effects on rice stem borer reached 90.4% and 94.2% at 7 and 14 days after treatment, respectively, which is significantly better than the control agent and has good promotion and application value.
Yangnong Chemical has made a breakthrough in the research and development of fipronil related applications, and has obtained an invention patent authorization for "a sanitary insecticide composition and its application". The active ingredients of this sanitary insecticide composition are compounded with specific compounds such as fipronil and thiacloprid, accounting for 1% to 80% of the total weight of the insecticide composition. This combination belongs to low toxicity or slightly toxic products, with high safety when used. In specific proportions, the compound agent exhibits a synergistic effect, and compared to a single agent, the knockdown and lethal effects are significantly improved. It is particularly suitable for hygiene pests that have developed resistance to pyrethroids, providing a new solution for hygiene pest control.
With the advancement of these projects and the continuous emergence of research and development achievements, the application of fipronil in agriculture and health fields is expected to be further expanded, playing a greater role in ensuring crop growth and maintaining environmental hygiene.
