Triflumezopyrim: A Leading Solution for Resistant Rice Planthoppers | Henan United Agro Biotechnology Forward-Looking Layout

 

Rice planthoppers, including brown planthoppers, white-backed planthoppers, and small brown planthoppers, are major destructive piercing-sucking pests in global rice cultivation. Long-term continuous application of traditional insecticides such as imidacloprid, pymetrozine, and nitenpyram has led to severe pest resistance year by year. Reduced control effects, increased dosage, and frequent virus disease transmission have become common pain points in modern rice planting. In this context, triflumezopyrim has become a highly recognized core compound in the agrochemical industry with its innovative mechanism and outstanding comprehensive performance.
 

What Is Triflumezopyrim?

 
Triflumezopyrim is the first commercialized mesoionic pyrimidinone insecticide, independently developed by Corteva. Classified as IRAC Group 4E with a unique action subgroup, it has no cross-resistance with mainstream conventional pesticides. Its core compound patent in China will expire in August 2030, bringing huge market potential for subsequent industrial layout.
 

 

CAS: 1263133-33-0
Molecular Formula: C₂₀H₁₃F₃N₄O₂
Core patent expiration date: August 2030 (China)

 
 
 

Core Advantages of Triflumezopyrim

 

Innovative Mechanism, Targeting Resistant Pests

 

 

Different from neonicotinoid insecticides, triflumezopyrim acts as a competitive inhibitor of insect nicotinic acetylcholine receptors. It blocks nerve conduction by binding to specific sites, causing pest paralysis and gradual death. It delivers stable control effects on highly resistant planthoppers and has no cross-resistance with common insecticides, being an essential tool for integrated pest management.

 

 

High Efficiency & Low Dosage

 

 

It features rapid action and stable performance. It can quickly inhibit pest feeding activity and effectively reduce the risk of disease transmission. With low effective ingredient dosage, it meets the modern agricultural needs of chemical fertilizer and pesticide reduction, saving planting costs for farmers.

 

Excellent Systemic & Rainfast Performance

 
 

With strong xylem systemic absorption and powerful leaf penetration, it is suitable for foliar spraying, seed dressing, and soil treatment. It can resist rain erosion after application, maintaining stable efficacy in rainy rice-growing areas and adapting to complex field environments.

 
 

Long Duration, Fewer Application Times

 

 

The effective duration can reach 21 to 28 days, effectively reducing spraying frequency, lowering labor input, and slowing down the further development of pest resistance.

 

 

Eco-Friendly & Wide Compatibility

 
 

It has high safety to aquatic organisms, natural enemies, bees, and soil organisms, fitting the development trend of green agriculture. Besides rice, it is also applicable to corn, cotton, soybeans, potatoes, and other crops. It can be compounded with fungicides and lepidopteran insecticides to realize simultaneous control of pests and diseases.
