辛勤劳作的果农们常常因果实果面药斑降低果品品质影响经济收入发愁。而造成果品药斑的原因却是因为果树喷洒了波尔多液后残留药害所致。而且波尔多液只能现用现配,且不能与其他农药混用,给果品生产带来麻烦。果农们企盼有一种既保留波尔多液优点又克服其缺点的替代产品。 Hard working fruit growers are often worried about the economic consequences of reducing fruit quality due to fruit-face drupes. The cause of the drug spot is because fruit trees spray Bordeaux mixture of residual drug damage caused. And Bordeaux mixture can only be used now with the available, and can not be mixed with other pesticides, fruit production to bring trouble. Farmers are looking forward to having an alternative that retains the virtues of Bordeaux mixture and overcomes its shortcomings.
