The invention relates to a bactericidal composition having a synergistic effect. The active ingredients of the bactericidal composition comprise propamidine and pyrimorph in a weight ratio of 1-60:80-1; and wettable powder, water dispersion and suspension can be prepared by adding an assistant and an excipient into the active ingredients. The bactericidal composition can effectively preventing and controlling gray mold, downy mildew, epidemic disease and the like in fruits and vegetables.

The invention discloses a fungicide composition containing eugenol and propamidine and an application of the fungicide composition. The fungicide composition comprises a common assistant, eugenol and propamidine at the ratio in parts by weight of (9 to 1) to (1 to 20); the weight percent of the sum of the eugenol and the propamidine in the composition is 3%-90%; the fungicide composition disclosed by the invention is suitable for preventing and treating crop diseases caused by fungal pathogens, especially crop gray mold caused by botrytis pathogens, as well as banded sclerotial blight, root rot, damping-off and the like of crops caused by rhizoctonia pathogens. The prevention and treatment effect of the composition disclosed by the invention has more obvious synergistic effect than that of a single dose; the dosage of the pesticide is reduced; the medication cost is reduced; the service life of the pesticide is prolonged; and adverse effects on the ecological environment caused by the pesticide are reduced.

The invention discloses a propamidine water dispersible granule (WDG) and a preparation method thereof. Prepared propamidine water dispersible granules comprise the following raw materials in percentage by weight: 85-90 percent of propamidine, 2.5-5 percent of dispersant, 2.5-5 percent of humectant and 2.5-5 percent of disintegrating agent, and the total percentage of the raw materials is 100. The preparation method comprises the steps as follows: the raw materials in a formula, including the propamidine, the humectant, the dispersant and the disintegrating agent, are uniformly mixed, crushed by an airflow crushing machine, and made into ultra-fine wettable powder, then the ultra-fine wettable powder is added with a certain amount of water, and made into granules via an extrusion type granulator, the granules are dried by an airflow drier, and screened and separated, as a result, the water dispersible granules are obtained. According to the invention, the cost of package and transport can be effectively reduced, the storage stability and the shelf life of the WDG are increased, the safety and the performance of environmental protection in links about the production and the utilization of the propamidine WDG are also improved, and the plant botrytis cinerea pathogenic bacterium can be very efficiently prevented and treated.

The invention discloses a pesticide composition with active ingredients being pyraclostrobin and propamidine. The pesticide composition contains a commonly-used auxiliary agent, pyraclostrobin and propamidine. Weight ratio of pyraclostrobin to propamidine is 20:1-1:20. The total weight of pyraclostrobin and propamidine in the pesticide composition is 3-90 wt%. After pyraclostrobin and propamidine are compounded, the pesticide composition has an obvious synergistic effect, and dosage of the active ingredients of the compounded medicine is obviously reduced in comparison with dosage of each active ingredient which is used separately. The pesticide composition is applicable to control crop diseases caused by pathogenic fungi, especially crops' gray mold caused by Botrytis pathogen and crops' gibberellic disease caused by Gibberella pathogen.

The invention provides a bactericidal composition. The bactericidal composition contains propamidine, validamycin and dichlorophenoxy triethylamine. The bactericidal composition provided by the invention has the advantages that due to bactericidal components and plant-growth adjusting substances, not only are the effects of killing bacteria and promoting growth achieved, but also mutual synergy among all the components can also be achieved; compared with the single component, the bactericidal composition has the advantages that the bioactivity is obviously enhanced, the bacteriocidal spectrum is expanded, and the bactericidal composition is safe for human and livestock and has no residue.
