One of fluorine and phosphorus germicidal compositions and preparations glucosamine sugars toxic polyene

The present invention relates to a germicidal composition and fungicides, the fungicidal composition containing toxic fluoride phosphate and glucosamine polyalkylene sugar, phosphorus and fluorine poisoning weight ratio of polyalkylene sugar is glucosamine 40: 1 to 1: 20, preferably the weight ratio of 30: 1 to 1:10. The present invention provides a fungicidal composition comprises from 0.1% to 80% of the total weight of the fungicide, bactericide for controlling the various viral and fungal crop diseases have obvious synergistic effect, greatly improve the control effect, reduce the use of agents volume, reduce costs and delay drug resistance.
