Problems solved by technology

In order to solve this problem, there are two main mainstream directions in the research of insect virus insecticides at home and abroad. One is to recombine insect viruses through genetic engineering to improve the insecticidal activity of insect viruses or expand their insecticidal spectrum. , Wuhan University once reported that using Bt to recombine the nuclear polyhedrosis virus containing Autographa californica, the insecticidal effect of the obtained recombinant virus was significantly improved and the insecticidal spectrum was significantly expanded, but the method was expensive and difficult to operate. So far, only one genetically engineered strain of cotton bollworm virus has been industrially produced in China; the second is to improve the insecticidal effect and insecticidal spectrum of virus insecticides through formulation compounding, which is nearly ten years old. The focus of domestic research in recent years, in terms of the 59 registered products of 22 insect viruses in the Ministry of Agriculture, in the past three years, 13 registered products are compound formulations of insect viruses, and the growth trend is obvious

Embodiment 1-5

[0028] A kind of biochemical compound pesticide preparation of controlling beet armyworm, formula is as shown in table 1:

[0029] Table 1 Biochemical Compound Pesticide Formulation Table Parts by Weight

[0030]

[0031]

[0032] Among them, the biopesticide is an insect virus insecticide. The chemical pesticides are one or a combination of emamectin benzoate, miman, tebufenozide, chlorfenapyr, cypermethrins, hexaflumuron, and diflubenzuron. The solvent is one or a combination of acetone, methanol, ethanol, ethyl acetate, trichloroethane, cyclohexanone, and isobutanol. The dispersant is one or a combination of sodium lauryl sulfate, sodium p-benzenesulfonate, fatty alcohol polyoxyethylene ether, and polycarboxylate. The auxiliary dispersant is silicone. The anti-sedimentation agent is one or a combination of magnesium aluminum silicate and xanthan gum. The antifreeze agent is one or a combination of ethylene glycol, propylene glycol, glycerol, and urea. The preserv...

Embodiment 6

[0034] A biochemical compound pesticide preparation for controlling beet armyworm, comprising 7 parts of biological pesticides, 3 parts of chemical pesticides, 30 parts of solvents, 7 parts of dispersants, 1 part of auxiliary dispersants, and 1 part of anti-sedimentation agents in parts by weight. Antifreeze 0.3 parts, water 50 parts, preservative 0.3 parts.

[0035] The biological pesticide is insecticide, the chemical pesticide is tebufenozide, the solvent is acetone, the dispersant is sodium lauryl sulfate, the auxiliary dispersant is silicone, the preservative is sodium benzoate, and the anti-sedimentation agent is magnesium silicate Aluminum, antifreeze is ethylene glycol.

Embodiment 7

[0037] The preparation method of the disclosed biochemical compound pesticide preparation of embodiment 1-6 comprises the following steps:

[0038] (1) at normal temperature, stirring and dissolving biological pesticides and chemical pesticides in a solvent to make an organic phase solution;

[0039] (2) Dissolving the dispersant, auxiliary dispersant, preservative and antifreeze in water to make an aqueous solution;

[0040] (3) While stirring at high speed in the reactor (stirring speed is 700r / min), slowly drop the prepared organic phase solution into the aqueous phase solution, then evaporate under reduced pressure, remove the solvent phase, and obtain the mixed solution A;

[0041] (4) Add the anti-sedimentation agent into the mixture A, turn on the shearing machine for high-speed shearing (shearing speed 100r / min-1200r / min), and shear for 20min-1h to form a uniform and stable water-suspended pesticide formulation.

[0042] When in use, the prepared water-suspended pesti...

Abstract

The invention relates to the technical field of pesticides, and discloses a biochemical compound pesticide preparation for controlling beet armyworm and a preparing method thereof. The pesticide preparation comprises the following components in parts by weight: 5-10 parts of a biological pesticide, 1-5 parts of a chemical pesticide, 20-30 parts of a solvent, 5-15 parts of a dispersant, 1-4 parts of an auxiliary dispersant, 1-3 parts of an antisettling agent, 0.1-0.5 part of an antifreezing agent, 40-60 parts of water, and 0.1-0.5 part of a preservative. The insect virus insecticides are mixedwith the chemical pesticide, the advantages of fast insecticidal speed and broad insecticidal spectra of the chemical pesticide are fully played, the characteristics of low toxicity and long lasting period of virus insecticides are reserved, and the use amount of the chemical pesticide is remarkably reduced. The biological pesticide is mixed with the chemical pesticide to prepare the environmental-friendly preparation-a suspension agent, so that the insect virus insecticide becomes a real green pesticide, and not only can kill pests efficiently and quickly but also reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a biochemical compound pesticide preparation for controlling beet armyworm and a preparation method thereof. Background technique [0002] An important measure to effectively prevent and control plant diseases and ensure high and stable yields is the correct use of pesticides. At present, the control of plant diseases and insect pests is still dominated by chemical control, but the long-term and large-scale unreasonable use of chemical pesticides has brought about a series of problems, such as the resistance of pests to various chemical pesticides to varying degrees, and pesticide residues in food. Exceeding the standard, endangering the natural enemies of pests, etc. Compared with chemical pesticides, biological pesticides have many advantages: (1) pollution-free, no residue, safe and environmentally friendly; (2) good environmental compatibility; (3) strong specificity, do ...
