Embodiment 1
[0019] 1. Material preparation process:
[0020] Select ripe wax gourd fruit, sun-dry or dry, and keep the weight water content of the fruit at 30% for subsequent use;
[0021] 2. Pressing and deoiling:
[0022] The above-mentioned wax gourd fruit is deoiled by pressing, and the temperature of the press is controlled to be 100° C., so that the oil in the wax gourd fruit is separated from the non-grease part, and the oil content in the pressed cake is 20%.
[0023] 3. Squeezed cake crushing and bagging:
[0024] The above-mentioned pressed cake (non-grease part) is pulverized, and the pulverization is in the range of 50-100 mesh, and bagged.
Embodiment 2
[0026] 1. Material preparation process:
[0027] Ripe wax gourd fruits are selected, sun-dried or dried, and the water content of the fruit is kept at 35% for later use.
[0028] 2. Pressing and deoiling:
[0029] The above-mentioned wax gourd fruit is deoiled by pressing, and the temperature of the press is controlled in the range of 80° C., so that the oil and non-grease parts in the wax gourd fruit are separated, and the oil content in the pressed cake is 40%.
[0030] 3. Squeezed cake crushing and bagging:
[0031] The above-mentioned pressed cake (non-grease part) is pulverized, and the pulverization is in the range of 50-100 mesh, and bagged.

Abstract
The invention relates to a biological herbicide manufactured by using the fruits of Idesia polycarpa var.vestita and a preparation method thereof. The fruits of the Idesia polycarpa var.vestita are dried, pressed, deoiled, pressed into cake shape and crushed to obtain the herbicide. The compound concentration of fruit residue is 80 to 90 percent. The effect of the fruit herbicide of the invention for controlling monochoria vaginalis is that: in a rice paddy field, after rice is transplanted and customized, each hectare is bestowed with 300kg to 900kg of the fruit residue of the Idesia polycarpa var.vestita; plant preventing effect on the monochoria vaginalis is that (the number of comparison plants minuses the number of treated plants) then divides the number of the comparison plants and then multiplies 100 percent; the fresh weight preventing effect of the monochoria vaginalis is that (the fresh weight of the comparison plants minuses the fresh weight of the treated plants) then divides the fresh weight of the comparison plants and then multiplies 100 percent. The results are that the plant preventing effect is 69.4 to 78.7 percent and the fresh weight preventing effect is 68.5 to 78.4 percent.
Description
technical field [0001] The invention relates to the technical field of biological herbicides, in particular to a fruit herbicide made from fresh plant fruits and a preparation method thereof. Background technique [0002] Because of its harmlessness to humans and animals, no pollution, and no residue, biopesticides have attractive development prospects and represent the future of the pesticide industry. Biopesticides will become mainstream products in the market in the near future. The development of biological pesticides, reducing the amount of pesticides used, and reducing the pollution of pesticides to the environment are of great significance to improving the yield and quality of crops and promoting the sustainable development of agriculture. At present, foreign research institutions are actively using the diversification of the structure and source of antibiotic compounds in plants (many medicines and pesticides are created using the toxic groups of natural active prod...
