Tupon is a global alternative Herbicide The development of the leading companies, the development of five butachlor mefluidide has become the global water and paddy China Herbicide The chief products. According to the company technical director Wang Chunlin said that in the past 20 years, to promote the Herbicide The most important factor in the rapid development of the market is: GM crops, weed resistance and raising the level of economic development. Among them, the level of economic development and Herbicide The development is directly related to labor costs.

The creation of new compounds to increase the difficulty

According to the latest research data Phillips McDougall, discovery, development and the average development cost of 1 effective components of a pesticide registration amounted to $286 million; successfully registered 1 new products average screening of 160 thousand new compounds; from 1 new active ingredients for the first time into its IPO took an average of 11.3 years. The 3 data over the past 256 million dollars, 140 thousand compounds and 9.8 years respectively increased 11.7%, 14.1% and 15.3%. in pesticide R & D costs to a new high, increasing the difficulty of the listing of new products.

Guo Jingquan believes that the herbicide discovery difficulty is decided by many factors. First of all, multinational companies invest in the development of herbicide reduction, this is mainly due to the impact of the listing of genetically modified crops. Secondly, the new standard increased the threshold of pesticides. He said that the development of a new compound, not only to ensure its activity and efficacy, also requires the environmental safety. The toxicology research is very complicated, not only including acute toxicity and chronic toxicity data (teratogenic, carcinogenic and mutagenic), reproductive toxicity and endocrine disruption. Multinationals tend to eliminate many very high activity compounds but with environmental and human risks. Therefore the investment reduction and raising the threshold has brought many new challenges for the innovation of herbicides.
