世界农药制剂发展将呈现以下四方面趋势: 水性化。活性物质分别为液态和固态的农药,加工制成在水中分散成溶液和乳化状及悬浮状剂,再用水稀释后喷洒。这样可避免使用大量有毒溶剂,降低易燃性、刺激性和经皮毒性。由于其活性物质粒径小于粉剂和可湿性粉剂,因而有更高的药效,并减轻药害,对作物不会产生污染,提高安全性。 The world pesticide development will show the following four trends: water-based. Active substances are liquid and solid pesticides, respectively, processed into water and dispersed into a solution and emulsifying and suspending agents, and then spray diluted with water. This avoids the use of large amounts of toxic solvents, reducing flammability, irritation and transdermal toxicity. Because of its active material particle size smaller than the powder and wettable powder, which has higher efficacy and reduce phytotoxicity on the crops will not produce pollution and improve safety.
