为寻找防治人参黑斑病的高效低毒新农药及抗菌素,来代替目前生产上大量应用的农药“田安”(系有机肿制剂,具有残毒)。我们作了近20余种新农药,农用抗菌素筛选工作。在中国科学院微生物研究所和上海农药厂大力支援与协助下,经两年室内外的试验,筛选出最有希望的农用抗菌素——“多抗霉素”。它是目前防治人参黑斑病的一种具有高效低毒的农用抗菌素,试验证明:采用100—200单位的“多抗霉素”,可相当或超过常用的“田安”农药。其防病效果在85—94.2％左右,而且使用方便,安全,无药害,药剂比较稳定,不易分解。现将防病试验结果总结如下:
In order to find out the effective and low toxicity new pesticides and antibiotics to prevent and cure ginseng black spot, instead of “Tian An” (organo-swollen agent, with residual poison) which is widely used in the current production. We made nearly 20 kinds of new pesticides, agricultural antibiotic screening. Under the strong support and assistance from Institute of Microbiology, Chinese Academy of Sciences and Shanghai Pesticide Factory, the most promising agricultural antibiotic “polyoxin” was screened out after two years’ indoor and outdoor experiments. It is currently a kind of agricultural antibiotic with high efficiency and low toxicity against ginseng black spot. The test proves that 100-200 units of “polyoxin” can be used as the equivalent or more than the commonly used “Tian An” pesticide. The anti-disease effect in 85-94.2% or so, and easy to use, safe, no injury, pharmaceutical more stable, not easy to break down. Disease prevention test results are summarized below:
