Problems solved by technology

However, these insect viruses, fungal spores, Bacillus thuringiensis and their toxin proteins are inevitably inactivated by ultraviolet (UV) radiation in the sun after being sprayed on the surface of agricultural and forestry plants, resulting in short pesticide residue periods and greatly reduced efficacy

Embodiment 1-9

[0036] A kind of biological pesticide synergist, in Central China, South China, Southwest China, each raw material and content (the described content is calculated by the mass percentage that each raw material accounts for biological pesticide powder) as shown in Table 1:

[0037] Table 1 Content unit: mass percent (wt%)

[0038]

[0039]

Embodiment 10-19

[0041] A kind of biopesticide synergist, in areas with high altitude and strong ultraviolet rays such as the northern region, the northwest region and the Qinghai-Tibet Plateau, each raw material and its content (the content is calculated based on the mass percentage of each raw material in the biopesticide powder) are shown in the table 2 shows:

[0042] Table 2 Content unit: mass percent (wt%)

[0043]

[0044] The preparation methods of the biopesticide synergists described in Examples 1-19 are all as follows: mix the raw material powders uniformly to obtain the product.

[0045] The use process is as follows: first dissolve the prepared biopesticide synergist in hot water at 60-100°C, then add enough water (normal temperature) according to the dilution factor of the biopesticide to be added, and finally add the biopesticide and stir evenly , to obtain highly active biopesticides, which can be directly used for field spraying.

application example 1

[0047] The biopesticide synergist is the formula in Example 4, and the raw materials are chlorogenic acid, rutin and dihydromyricetin, and the biopesticide is sweet nucleus thuringiensis wettable powder, and its dilution factor is 1000 times. The prepared highly active biopesticide is directly used for spraying in mulberry field. The place of the experiment is Wuhan Botanical Garden of Chinese Academy of Sciences, the weather of the experiment is sunny in summer, and the poisoning objects are the feeding silkworms. The wettable powder of the biological pesticide sweet nucleus thuringiensis without adding synergists is used as the control, and the statistics will start the next day after spraying Bombyx mori mortality, statistical time is 20 days, the first 1-6 days, the silkworm mortality of the experimental group and the control group are all at 100%, the 7th-20th day, the silkworm mortality of the control group gradually drops to 30%, the experimental group The death rate of...

Abstract

The invention belongs to the technical field of synergists and particularly relates to a biopesticide synergist. The biopesticide synergist comprises plant flavone, plant polyphenol and plant quinones compounds; natural plant products are enriched with conjugated systems and ultraviolet light in sunlight can be absorbed, so that the biopesticide synergist has the functions of protecting virion, fungal spores and bacterial spores, and preventing toxalbumin from being damaged by the ultraviolet light; the biopesticide synergist also has the functions of enhancing the pathogenic activity of the virion and the toxalbumin and protecting crops and vegetables from being damaged by the ultraviolet light so as to promote the growth; the biopesticide synergist has a certain food refusal effect on insects, can also inhibit pathogenic bacteria from being spread, and has a certain effect on preventing crop diseases. Therefore, the technical scheme brings obvious economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of synergists, in particular to a biological pesticide synergist. Background technique [0002] Biopesticides are a type of pesticide preparations that use living organisms of natural enemies or their metabolites to control pests, germs, weeds, nematodes, rodents and other harmful organisms. In China, biological pesticides refer to insect virus preparations, bacteria (such as Bacillus thuringiensis) and their spores and toxic protein preparations, and fungal spore preparations. However, these insect viruses, fungal spores, Bacillus thuringiensis and their toxin proteins are inevitably inactivated by ultraviolet (UV) radiation in sunlight after being sprayed on the surface of agricultural and forestry plants, resulting in a short residual period of pesticides and a greatly reduced efficacy. The infection activity of insect virus preparations dropped sharply to less than 20% after being exposed to sunlight fo...
