Embodiment 1

[0043] Step 1, extract preparation.

[0044] Weigh 10kg of cloves and 90kg of cinnamon, mix or crush them through a 40-mesh sieve, soak in an aqueous solution of sodium chloride, the ratio of the extraction material to the extraction solution is 1:10, distill and extract in a reaction kettle, the extraction temperature is 80-100°C, The extraction time was 3 hours, the steam was discharged, filtered, and the filtrate was left to stand and separated to obtain the extract essential oil, which was extracted twice in the same way, and the two essential oils were combined to obtain the extract.

[0045] Step 2, preparation of bactericide aqueous solution.

[0046] Add 35kg of total plant extract essential oils, 25kg of ethanol, 9kg of alkylphenol polyoxyethylene ether surfactants, 6kg of penetrating agent in the reaction kettle, mix and dissolve, add 25 kg of water to dissolve, and stir under high shear to obtain cinnamaldehyde aqueous emulsion or microemulsion.

[0047] The obtai...

Embodiment 2

[0056] Field test result of compound botanical fungicide of the present invention for controlling gray mold of cucumber.

[0057] Test object: Cucumber Botrytis.

[0058] Test method: The area of ​​each test plot is 5 square meters, and each treatment is repeated 3 times. Set clean water as the control, and set the control chemical pesticide 50 procymidone wettable powder. Spray twice in mid-August with an interval of 7 days. The diseased leaves in each area were removed before the first spraying, and the disease index was counted one week after the second spraying, and the control effect was calculated.

[0059] Test results: The test results are shown in Table 2, which shows that the compound botanical fungicides have good control effects on cucumber gray mold, and are better than the local commonly used drug saccharin.

Abstract

The invention discloses a compound botanical fungicide which is characterized by comprising the following components in percentage by mass: 0.1 to 30 percent of cinnamaldehyde, 0.1 to 3 percent of eugenol, 8 to 15 percent of emulsifier, 8 to 15 percent of solvent and the balance of water. The invention also provides a preparation method which comprises the following steps of: 1, extracting plant essential oil; 2, extracting active ingredients; 3, mixing and dissolving the components except for the water and auxiliaries; and 4, preparing a waterborne environmental-friendly pesticide formulation. The botanical fungicide clove and cinnamon mixture prepared by the preparation method disclosed by the invention comprises the main active ingredients of cinnamaldehyde and eugenol; the two different types of active ingredients are mutually synergetic and have complementary effects; compared with the mode of separately and respectively using the active ingredients, the mode of simultaneously using the active ingredients has obvious synergism; the cost is also greatly reduced; a fungicide spectrum is improved; and the compound botanical fungicide also has a strong inhibition effect on multi-target plant pathogenic fungi. The fungicide spectrum is wide and the combination of different types of active ingredients is difficult to generate the drug resistance.

Description

technical field [0001] The invention relates to the field of pesticides and their preparation techniques, in particular to a compound botanical fungicide and a preparation method thereof. Background technique [0002] The application of chemically synthesized pesticides has the characteristics of good control effect and quick effect, and is currently one of the important means of pest control. However, long-term and unreasonable use of chemically synthesized pesticides in large quantities, especially highly toxic and high-residue pesticides, will cause pesticide residues to exceed the standard, pollute the environment and agricultural products, endanger human and animal health, develop resistance to pests and diseases, reduce the control effect, and even kill a large number of natural enemies, causing Pests and diseases are rampant again, disrupting the biological balance. This is the so-called "3R" problem of chemical pesticides. [0003] Botanical pesticides have the cha...
