AgroPages-DowDuPont to promote novel rice planthopper insecticide Pexalon™ in China-Agricultural news

A novel rice planthopper insecticide application training workshop for 2017 was held jointly by the National Agro-Tech Extension and Service Center (NATESC) and DowDuPont on 23rd October. The workshop focuses on the application of DuPont’s Pexalon™ (triflumezopyrim 10% SC), which prevents and controls various rice planthoppers quickly and effectively. The product is also rain wash-resistant, environment-friendly and safe for use. After long years of experiment and demonstration, the product has become well recognized by crop protection practitioners.

In China, the resistance ratio of brown planthopper is above 1,200 for the first-generation neonicotine pesticide imidacloprid, 200–500 for the second-generation neonicotine pesticide thiamethoxam and 500 for buprofezin, which can be above 1,000 in the Yangtze River area. The effectiveness of pymetrozine against the brown planthopper has decreased continuously, while the resistance of brown planthopper has continued to increase.

The active ingredient of Pexalon™ is the innovative mesionic chemical compound triflumezopyrim, it being the only one among the IRAC Group 4 that can inhibit but won’t activate the nicotinic acetylcholine receptors. Therefore, there is no cross resistance between Pexalon™ and neonicotine pesticide，and as such, Pexalon™ has a speedy and long-lasting effectiveness over all kinds of rice planthoppers.

After spraying,Pexalon™ penetrates rapidly into crops with its good penetration capacity and systemicity, which not only enable crops to be rain wash-resistant but also provide a long-lasting effect. It covers crops and protects crops from insect pest, as well as keeps away planthoppers and the spread of viral diseases, thus enabling a long-term control of mixed population of planthoppers. Additionally, it can be absorbed by crop root and then transmitted to the overground part of crops to exert its function effectively through soil treatment.

Furthermore, Pexalon™ is of friendly environmental attribution and micro toxicity. It is easy to apply while relaxing the operator’s clothing requirement and being protective toward beneficial arthropod community. Its application causes very little residues in the environment, and these residues are minimal within the harvested crops. This helps reduce the risks of trade barrier.

Peter Ford, President, Agricultural Division Asia Pacific and HuangTianqiang, Chief Executive, Great China Region of DowDuPont, both emphasized that every effort was being made to prepare the market launch of Pexalon™. Ford said, “After the DuPont-Dow merger, the new DowDuPont is destined to make greater contribution to agriculture. The China team of DowDuPont are aware of the challenges to Chinese agriculture, and we will continue our cooperation with NATESC in more depth to provide growers and consumers with diversified services.”
