Bactericidal composition containing tridemorph

Abstract

The invention discloses a bactericidal composition with synergistic interaction. The composition contains the active components of (A) tridemorph and (B) one of methoxy acrylic acid ester bactericides in a weight ratio of 32:1-1:32. The an auxiliary agent and an excipient agent are added into the active components to prepare a suspoemulsion and a suspending agent for control of diseases caused by bacteria of Ascomycetes, basidiomycetes and Fungi imperfecti.

The original application is a patent application for "a bactericidal composition containing tridecamorpholine" by Shaanxi Meibang Pesticide Co., Ltd.. The application number of the original application is: 201010579234.8, and the original filing date is 2010.12.8. Technical field

[0002] The invention belongs to the field of agricultural fungicides and relates to the preparation and application of a fungicidal composition containing tridecamorpholine. Background technique

[0003] With the sustainable development of agriculture, human beings are increasingly aware of environmental protection. The impact of agricultural chemicals on the environment has attracted much attention. Due to the extensive use of chemical pesticides, air, water sources, soil and crops have been polluted to varying degrees. . Therefore, it has become a trend in pesticide research and development to reduce the use of chemical pesticides and introduc...

[0084] 1. Preparation of suspoemulsion

[0085] When the composition is made into a suspoemulsion, it includes the following components: active ingredient A 1-40%, active ingredient B 1-40%, emulsifier 2-12%, dispersing wetting agent 2-10%, defoamer 0.1-2% %, thickener 0.1~2%, antifreeze agent 0.1~8%, stabilizer 0.05~3%, water added to 100%.

[0086] Mix the dispersant, defoamer, thickener, antifreeze, and stabilizer in the above formula evenly through high-speed shearing, add active ingredient A original drug, and ball mill in a ball mill for 2 to 3 hours to make the particle size completely Prepare a suspension below 5 μm, and then directly emulsify the active ingredient B original drug, emulsifier and various auxiliary agents into the suspension with a high-speed stirrer to obtain the suspoemulsion product of the present invention.
