example 1

[0028] Example 1: (Buliuxing extract)

[0029] The extraction process of the extract is as follows: 30% ethanol leaching method for the seeds of wangbuliuxing, the mass volume ratio is 1:5, decocting 3 times, 60min each time, combining the filtrates, vacuum concentrating to a density of 1.1g / cm³, Among them, flavonoid glycosides contain 30%, saponins contain 60%, and cyclic peptides contain 10%.

example 2

[0030] Example 2: (Buliuxing extract)

[0031] The extraction process of the extract is as follows: the seeds of wangbuliuxing are leached with 50% ethanol, the mass volume ratio is 1:8, decocted 3 times, each time for 50 minutes, the filtrates are combined, concentrated in vacuum to a density of 1.1g / cm³, Among them, flavonoid glycosides contain 70%, saponins contain 20%, and cyclic peptides contain 10%.

example 3

[0032] Example 3: (Buliuxing extract)

[0033] The extraction process of the extract is as follows: 90% ethanol extraction method for the seeds of Wangbuliuxing, the mass volume ratio is 1:10, decocting 3 times, 30min each time, combining the filtrate, vacuum concentration to a density of 1.1g / cm³, Among them, flavonoid glycosides contain 30%, saponins contain 10%, and cyclic peptides contain 60%.

Abstract

The invention discloses a preparation method of a botanical extract biopesticide preparation and an application thereof, and relates to a preparation method and an application of a biopesticide preparation. A cowherb seed extract containing multiple components is processed into a preparation to be used for preventing and treating common plant diseases, and the preparation is processed into soluble liquid, microemulsion, emulsion in water, a suspending agent, water dispersible granules and the like, and is used for preventing and treating fungal diseases such as cucumber corynespora leaf spot, tomato early blight, cucumber downy mildew, wheat scab and the like, and bacterial diseases such as cucumber bacterial angular leaf spot, citrus fester disease, Chinese cabbage soft rot and the like. The biological pesticide can be applied to plant virus diseases such as tobacco mosaic virus (TMV), potato Y virus (PVY), tomato yellow leaf curl virus (TYLCV), tomato spotted wilt virus (TSWV), rice stripe disease, pepper virus disease and the like, accords with national carbon peak reaching and carbon neutralization policies, maintains national grain safety, environmental safety and health and safety guarantee of people, and has wide application prospects and conversion values.

Description

technical field [0001] The invention relates to a preparation method and application of a biopesticide preparation, in particular to a preparation method and application of a plant source extract biopesticide preparation. Background technique [0002] In addition to the progress of production technology and the hard work of farmers, the use of pesticides and chemical fertilizers has also made a significant contribution to agricultural harvests. However, long-term dependence and extensive use of organic synthetic chemical pesticides have brought about well-known environmental pollution, ecological balance damage and A series of issues such as food safety have brought many adverse effects on promoting the sustainable development of the agricultural economy. Compared with chemical pesticides, biological pesticides have the advantages of being safe for humans and animals and not polluting the environment. In particular, plant extracts have the characteristics of multiple active ...
