specific Embodiment approach 1
[0010] Embodiment 1: In this embodiment, the botanical fungicide is made from 0.5-2 parts of Daphne chamaejasme, 0.5-2 parts of licorice, 0.5-2 parts of aconitum and 0.5-2 parts of Sophora flavescens in parts by weight.
specific Embodiment approach 2
[0011] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the botanical fungicide consists of 0.8-1.5 parts Daphne chamaejasme, 0.8-1.5 parts of licorice, 0.8-1.5 parts of aconitum and 0.8-1.5 parts of licorice by weight. Made from 1.5 parts Sophora flavescens.

The invention relates to a botanical fungicide and the preparation method thereof, which relate to a fungicide and the preparation method. The invention solves the shortcomings of the existing fungicide in severe environmental pollution and resistance due to long-term use. The botanical fungicide of the invention is made from stellera chamaejasme, liquorice, aconite and radix sophorae falvescentis. The method of the invention comprises the steps of: 1. weighing and mixing the stellera chamaejasme, liquorice, aconite and radix sophorae falvescentis; 2. leaching the ethanol; 3. filtering; 4. distilling; 5. moist heat sterilization. The botanical fungicide of the invention has the advantages of innocuity, low residuals, small dosage, no pollution, no resistance, strong bacteriostatic activity, high selectivity, diversified raw material sources, easy match with other biological pesticides, etc. The method of the invention has the advantages of simple process, and low cost. Compared with the chemical agent, the Chinese herbal medicine fungicide has the advantages of many active sites, long agent duration, high degradation speed, small pollutions to the environments, etc.
Description
technical field [0001] The invention relates to a fungicide and a preparation method thereof. Background technique [0002] Chemical agents play an important role in the control of crop diseases and insect pests. However, due to the long-term use of chemical agents, the frequency of resistance to diseases and insect pests in most areas exceeds 50%, and the resistance level is as high as more than 10,000 times. The single use of chemical agents has completely lost the control effect. Moreover, with the continuous enhancement of resistant strains, the frequency of pesticide application has increased year by year, and the amount of pesticide application has also doubled, which has brought great pressure to the control and the surrounding environment. Its disadvantages are also becoming more and more prominent, such as drug residues, environmental pollution and harmful organisms rampant again. Contents of the invention [0003] The object of the present invention is to solve ...
