Problems solved by technology

[0005] At present, chemical pesticides and fungicides are usually used to prevent and control crocus diseases, and the environmental pollution caused by the extensive use of chemical pesticides is becoming more and more serious
At the same time, the use of chemical pesticides and fungicides can cause plant pathogenic bacteria to develop drug resistance and drug resistance, which increases the difficulty of control and even causes the failure of control.
In addition, chemical pesticides pose a threat to beneficial organisms because they are not selective
Moreover, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants, resulting in the enrichment of pollutants

Abstract

The invention provides a preparation method of a natural bactericide for preventing and treating crocus sativus L. black spot. The method comprises the followings steps: smashing and screening raw materials, and mixing uniformly to obtain a mixture, wherein the raw materials comprise torreya grandis fruit, shiroishi date, mountain spicy tree fruit, chinese soapberry fruit, soapberry, ocimun basilicum L. fruit, phoenix tree seed, semen ziziphi spinosae, pulp of cornus and radix ranunculi ternate; adding the mixture into an ethanol aqueous solution, heating and decocting; filtering, collecting a filtrate, adding filter residues into the ethanol aqueous solution, heating and decocting; filtering, combining the filtrates, concentrating till the amount of the combined filtrate is 1 / 20 to 1 / 10 of the total adding amount of ethanol, adding water in an amount being 1 to 3 times of the amount of the combined filtrate, and standing; filtering, concentrating the filtrate till ethanol smell disappears, and adding water in an amount being the same as that of the concentrated filtrate for dissolving to obtain the natural bactericide for preventing and treating the crocus sativus L. black spot. The natural bactericide for preventing and treating the crocus sativus L. black spot is abundant in raw material sources, is low in cost, is made of pure natural components, is nontoxic and pollution-free, and can be used for effectively preventing and treating the crocus sativus L. black spot.

Description

technical field [0001] The invention belongs to the field of preventing and controlling diseases and insect pests, in particular to a natural fungicide for preventing and controlling saffron black spot and a preparation method thereof. Background technique [0002] Saffron (scientific name: Crocus sativus L.), also known as saffron and saffron, is a perennial flower of the genus Crocus in the family Iridaceae, and is also a common spice.
