Abstract

The invention relates to a bactericidal composition. The bactericidal active composition comprises the active components of copper calcium sulphate and zineb and the weight ratio of the copper calcium sulphate to the zineb is 1:100 to 100:1, wherein the mass of the copper calcium sulphate and the zineb accounts for 7 percent to 75 percent of the total mass of the composition. The bactericidal composition provided by the invention compounds the copper calcium sulphate with the zineb, has a synergetic effect, can treat fungal and bacterial diseases in soil, has multiple functions, expands the disease prevention spectrum, reduces the use quantity of the copper calcium sulphate and is safer to use. The bactericidal composition is used for soil processing or seed soaking (dressing), can prevent seed rot and root rot which are caused by soil diseases, ensures full stands, reduces diseases in the seedling stage and has better effects.

Description

technical field [0001] The invention relates to a bactericidal composition for agricultural or gardening applications, in particular to a bactericidal composition containing copper calcium sulfate and zinc zinc as active components. Background technique [0002] In recent years, many diseases have developed resistance to the currently used pesticides. On the one hand, frequent application of pesticides has increased the economic burden of farmers. pollution. Therefore, need a kind of high-efficiency, low toxicity, environment-friendly bactericidal shape variety. Contents of the invention [0003] In order to solve the above problems, the technical problem to be solved by the present invention is to provide a high-efficiency, low-toxicity, and environment-friendly bactericidal composition suitable for agricultural use. [0004] The technical scheme of the present invention to solve the above-mentioned technical problems is as follows: a kind of bactericidal composition, d...
