Plant pesticide and preparation method thereof

Abstract

The invention discloses a plant pesticide which is prepared from the following materials in percentage by weight: 25 to 35 percent of Chinese tallow tree, 15 to 25 percent of Eucalyptus robusta, 8 to 14 percent of groundsel, 30 to 40 percent of garlic, and 2 to 6 percent of Bidens bipinnata, wherein the garlic is raw and the other four materials are dry. The invention also discloses a method for preparing the plant pesticide. The method comprises the following steps: grinding and mixing the Chinese tallow tree, the Eucalyptus robusta, the groundsel, the garlic and the Bidens bipinnata; soaking in hot water for extraction; filtering the extraction liquid to obtain a mother liquid; and adding lead-free kerosene into the mother liquid to perform emulsification. The plant pesticide has the characteristics of broad antimicrobial spectrum, less possibility of causing resistance, low construction cost and the like; and the plant pesticide can be widely applied to control on fungal and bacterial diseases of grains, fruits, vegetables, Panax pseudo-ginseng, tobaccos, flowers and forests.

Description

technical field [0001] The invention relates to a fungicide for plants and a preparation method thereof. Background technique [0002] Chemical agents play an important role in the antibacterial and bactericidal aspects of crops, but they are prone to drug resistance and lead to the deterioration of the natural ecosystem. Therefore, in order to reduce or eliminate the poison of chemical substances, many experts and scholars have devoted themselves to the development of plant drug sources Utilize, also produced a large amount of results, wherein, Chinese patent literature CN1433695A discloses a kind of fungicide utilizing tripterygium wilfordii, wild cotton, garlic and other plants to make, and this fungicide obtains good effect, has put into factory production now. Since botanical fungicides are still in the initial development stage, some pharmacological mechanisms are still unclear and the production process is not mature enough, botanical fungicides generally have problem...

[0002] Chemical agents play an important role in the antibacterial and bactericidal aspects of crops, but they are prone to drug resistance and lead to the deterioration of the natural ecosystem. Therefore, in order to reduce or eliminate the poison of chemical substances, many experts and scholars have devoted themselves to the development of plant drug sources Utilize, also produced a large amount of achievements, wherein, Chinese patent literature CN1433695A discloses a kind of fungicide that utilizes tripterygium wilfordii, wild cotton, garlic and other plants to make, and this fungicide obtains good effect, has put into factory production now.

Since botanical fungicides are still in the primary development stage, some pharmacological mechanisms are still unclear and the production process is not mature enough, botanical fungicides generally have problems such as narrow antibacterial spectrum and high cost, which are not easy to be accepted by farmers
