新农药开发越来越难,这是不存在争议的共识。具体表现在:一是筛选新的农药活性物质难度越来越大,二是开发成功一个新的农药活性物质花费的费用越来越多,三是开发成功一个新的农药活性物质所需要的时间越来越长,四是开发成功新的农药活性物质的机遇越来越小而风险却越来越大。专家分析指出,受到农药的抗性、环保要求提高以及原料成本、生产成本上涨等影响,全球近10年来投入市场的新农药
The development of new pesticides more and more difficult, this is not controversial consensus. Specific performance: First, the screening of new pesticide active substances more and more difficult, and second, the successful development of a new pesticide active substances cost more and more, the third is the successful development of a new pesticide active substance required time Longer and longer, the fourth is the opportunity to develop successful new pesticide actives smaller and smaller and the risk is increasing. Expert analysis pointed out that by the resistance of pesticides, environmental protection requirements and increased raw material costs, rising production costs and other effects, the world nearly 10 years into the market of new pesticides
