Embodiment 1

[0026] Accurately weigh and analyze the content of pyrethrins in the refined natural pyrethrins. Add the stabilizer BHT (p-methylphenol) with 0.2% to 0.5% of the pyrethrins in the original medicine, and add 50% of the pyrethrins in the original medicine. ~300% of the synergist red orange oil is stirred to dissolve, dilute the emulsifier (5201) with an appropriate amount of acetone solution, and then add the 10-30% emulsifier of the pyrethrin content in the original drug, and stir well, then add the turpentine oil (Eucalypt globulus). Oil) to the pyrethrin content of 0.5 to 5% to obtain a natural pyrethrin EC preparation.

[0027] The obtained natural pyrethrin EC preparation is used as a fungicide for Botrytis cinerea, Colletotrichum capsicum, Cucumber Blight, Early blight, Fusarium graminearum, Fusarium moniliforme, Fusarium wilt of watermelon, Rhizoctonia solani . Specific usage: Dilute the natural pyrethrin EC with water 200-1000 times (different dilution times for different di...

Abstract

The present invention is the application of natural pyrethrin emulsifiable concentrate preparation as a fungicide. As a fungicide for wheat head blight and wheat sheath blight. The invention is a pure natural plant-derived fungicide, and its solvent, synergist and stabilizer are all plant extracts; there is no residue, and pyrethrins are decomposed into water and carbon dioxide in nature. It has low toxicity and no residue, and does not cause phytotoxicity to plant seedlings, flowers, and fruits, and there is no phytotoxicity when excessive use. The natural pyrethrin emulsifiable concentrate preparation of the present invention can be used for preventing and treating plant diseases, and opens up a new field for the application of pyrethrum. The pyrethrin emulsifiable concentrate preparation of the present invention can become an important bactericide in the production of green food and organic food because it has no residue and can be produced in large quantities.

Description

Technical field [0001] The invention relates to a bactericide, especially the application of natural pyrethrin emulsifiable concentrate as a bactericide. Background technique [0002] Pyrethrum has always been regarded as an insecticidal plant, and the application of pyrethrum has always stayed on the exploration of its insecticidal effect. And so far there is no report and application about the use of pyrethrum as a fungicide. Summary of the invention [0003] The purpose of the present invention is to provide a new use of natural pyrethrins, that is, natural pyrethrin EC preparations are used as fungicides for the prevention and control of plant diseases. [0004] The patent "a natural pyrethrin emulsifiable concentrate" previously applied by the applicant is mainly developed for plant pests. It can improve the insecticidal effect, has no residue, is harmless to humans and animals, and does not produce phytotoxicity to plants. [0005] The technical scheme of the present inven...
