Abstract

The invention discloses a botanical bactericide and a preparation method thereof. The botanical bactericide uses purely natural plant essential oil as effective bactericidal components and is prepared by using the following raw materials in percent by mass: 15-25 percent of turpentine, 10-20 percent of tea tree oil, 10-25 percent of camphor tree oil, 20-30 percent of eucalyptus oil, 5-10 percent of thickener, 2-4 percent of suspending agent and 5-8 percent of emulsifying agent. The botanical bactericide provided by the utility model is suitable for crops such as vegetables, melons and grains, can be used for preventing and controlling major diseases such as powdery mildew, rust diseases, net blotch and gray mold caused by ascomycetes, basidiomycetes and oomycetes, and has the advantages of wide bactericidal scope, environmental friendliness, high safety and the like.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, in particular to a novel botanical fungicide and a preparation method thereof. Background technique [0002] Since the 1940s, chemical pesticides have dominated the pesticide market due to their variety, quick effect, convenient use, and low price. However, due to people's unreasonable use of chemical pesticides and the inherent shortcomings of pesticides, the use of chemical pesticides has caused problems such as environmental pollution, human and animal poisoning, and pesticide residues. With the improvement of people's quality of life and the enhancement of environmental awareness, the development of biopesticides that are safe for humans and animals, non-polluting, low-toxic, and low-residue has become a new hot spot in the field of pesticide research. [0003] As a part of biologically rational pesticides, the development and research of botanical pesticides has always been one of the...
