在尽可能少使用化学农药的前提下，利用对病原菌生长与扩展有机械阻隔作用、无污染的成膜剂，生产高性能、无污染、成本低的新型无公害果树病害农药果病清。为了确定合理的配比和说明其利用价值，采用生长速率法对不同配比的药剂，在室内条件下作用于有代表性的病菌上，测定其 In the least possible use of chemical pesticides under the premise of the use of growth and expansion of pathogens have a mechanical barrier, non-polluting film-forming agent, the production of high performance, pollution-free, low cost of new pollution-free fruit tree disease pest disease clearance. In order to determine the reasonable ratio and explain the value of its use, the growth rate method for different proportions of drugs, under laboratory conditions on the representative of the bacteria, measured
