Problems solved by technology

Chemical control is an effective method to control plant diseases. It has the advantages of quick effect, wide bactericidal spectrum, low cost, and easy use. However, long-term and large-scale use of chemical fungicides will cause environmental pollution such as soil and air, and destroy ecological balance.
With the concern of food safety and environmental pollution in recent years, the use of some chemical fungicides has been strictly restricted in many developed countries and regions

Embodiment 1

[0045] A composition (microemulsion) for plant disease control, formulated by weight percentage from the following raw materials:

[0046] Sophora sophora alkaloid: 11%, biocontrol bacteria fermentation broth 47%, water-soluble iron salt 4%, organic solvent (ethyl acetate): 15%, surfactant (phenylethylphenol polyoxyethylene ether): 10% , synergist (synergist amine): 9%, antifreeze agent (ethylene glycol): 6%, surplus is water, and the weight percent sum of raw material is 100%; The preparation method of this microemulsion is: the raw material formula Weigh, add and mix sequentially, stir in the reaction kettle to be transparent, and finally make the finished product after quality inspection.

[0047] Wherein, the preparation method of Sophora alopecia alkaloids is: using Sophora sophora as a raw material, crushing Sophora sophora, using 75% ethanol aqueous solution with pH=4.5 (using tartaric acid to adjust acidity) of 12 times the dry weight (w / w) of Sophora sophora powder ,...

Embodiment 2

[0055] A composition (water emulsion) for controlling plant diseases is formulated by weight percentage from the following raw materials:

[0056] Sophora sophora alkaloid: 11%, 47% of biocontrol bacteria fermentation liquid, 4% of water-soluble iron salt, organic solvent (ethanol): 10%, surfactant (sodium dodecylbenzenesulfonate): 8%, increased Efficacy agent (organic silicon): 5%, antifreeze agent (ethylene glycol): 6%, thickener (polyvinyl alcohol): 0.3%, surplus is water, and the weight percent sum of raw material is 100%;

[0057] The preparation method of the aqueous emulsion is as follows: weighing the raw materials according to the formula, adding and mixing in sequence, finally emulsifying and dispersing under the action of a high-speed shearing machine, and finally making a finished product after quality inspection.

[0058] Wherein, the preparation method of Sophora alopecia alkaloids is: using Sophora sophora as a raw material, crushing Sophora sophora, using 75% e...

Embodiment 3

[0070]The indoor toxicity of the active ingredients of the composition of the present invention to pests (such as aphids) is measured by the method of soaking leaves with insects, and the results are shown in Table 1;

[0071] The method of determination is as follows: Indoor bioassay on aphids by soaking insects and leaves: first dilute the test agent with water into a mother solution, then dilute it into 6-7 concentration gradients, and then put the selected test insects and leaves together in the solution After immersing in the medium for 5s, take out the medicinal liquid with absorbent paper, put it into a 9cm petri dish covered with filter paper that has been moisturized in advance; treat 90-120 aphids per concentration for each dish of 30-40 aphids; treat with water for 8 hours Finally, check the number of death of the test insects. If the control mortality rate is higher than 20%, the test will be invalidated on the same day. Otherwise, after correcting the mortality rat...

Abstract

The invention provides a composition for preventing and eliminating plant diseases, and belongs to the field of prevention and elimination of plant diseases. The composition comprises the following effective ingredients by weight percentage: 10-50% of biocontrol bacteria fermentation liquor, 1-5% of water soluble ferric salt and 1-15% of alkaloid of sophora alopecuroide; the composition is prepared by compounding the effective ingredients and an additive, and a preparation of the composition is a missible oil agent, a microemulsion or an EW (emulsion in water), wherein biocontrol bacteria comprise fluorescent pseudomonades and bacillus subtilis; the water soluble ferric salt is prepared by compounding ferric salt and ferrous salt at the mass ratio of 1:(2-4); salicylic acid and citronellolare added into a bacteria solution for ultrasonic mixing before the biocontrol bacteria fermentation liquor is mixed with the water soluble ferric salt. The composition for preventing and eliminatingthe plant diseases has the advantages of being non-toxic, harmless and pollution-free and generating no drug resistance; the composition is used for preventing and eliminating the diseases in two aspects of inhibiting the growth of pathogenic bacteria and reinforcing the growth vigour of plants, so that the composition is strong in anti-bacterial and sterilizing effects and can also be used for improving the growth immunity of the plants.

Description

technical field [0001] The invention belongs to the field of plant disease control, and in particular relates to a composition for plant disease control. Background technique [0002] Plant disease is a phenomenon in which plants undergo a series of morphological, physiological and biochemical pathological changes under the influence of biological or abiotic factors, hindering the normal growth and development of plants, thereby affecting economic benefits. At present, plant disease control mainly relies on chemical pesticides. Chemical control is an effective method to control plant diseases. It has the advantages of quick effect, wide bactericidal spectrum, low cost, and easy use. However, long-term and large-scale use of chemical fungicides will cause environmental pollution such as soil and air, and destroy ecological balance. With the concern of people on food safety and environmental pollution in recent years, the use of some chemical fungicides has been strictly rest...
