The Exploitation And Research Of 30% Cuppric Nonyl Phenolsulfonate ME

30% cuppric nonyl phenolsulfonate ME is a kind of organic copper fungicide which is effective to resist some fungal diseases and virosis of plant.The preparation was researched on terms of compose technique, toxicity and the effect of disease control. The 30% cuppric nonyl phenolsulfonate ME has been got the temporary register of fungicide in the ministry of agriculture of China. The results of this research are as follows.1. The course for composing the production, cuppric nonyl phenolsulfonate, was designed, and did some research on optimizing the condition of the technique in the laboratory.2. The directions for producing 30% cuppric nonyl phenolsulfonate ME were researched. It demonstrated that the emulsifier A, which present high capability of emulsification and reserve, is fit for the technical toxicant.3. The enterprise standard was established relying on quality analysis of 30% cuppric nonyl phenolsulfonate ME.4. As a fungicide to resist virosis of plant, 30% cuppric nonyl phenolsulfonate ME showed the same effect of disease control with other fungicides which used to resist virosis of plant. The rate of disease control respectively were 59.6%,59.0%,and 55.5% when this fungicide was diluted in 500 -fold, 700-fold and 900-fold. It gave effective disease control during a long period.
