Embodiment 1

[0024] Weigh 200g of Coptis rhizome, crush it, add 800mL of water, extract at 70°C for 1.5 hours, filter, add 800mL of water to the filter residue and continue to extract for 1 hour, combine the filtrates, filter, concentrate under reduced pressure, and use water to make up the concentration of berberine to 56%. The above extract was mixed with 25 g of shredded tobacco, soaked for 4 hours, dried at 60° C. for 12 hours, pulverized, and passed through a 60-mesh sieve to obtain shredded tobacco berberine. Take 20g of shredded tobacco berberine, mix with 10g of sodium lignosulfonate evenly, then add 10g of ammonium chloride, 10g of Artemisia annua (crushed) and mix, and add 50g of aluminum nitrate. Pulverize and pass through a 60-mesh sieve to obtain the berberine smoke product.

Embodiment 2

[0026] Weigh 200g Cortex Phellodendri, pulverize, add 800mL 50% ethanol, extract at 70°C for 1.5 hours, filter, add 800mL 50% ethanol to the filter residue and continue to extract for 1 hour, combine the filtrates, filter, concentrate under reduced pressure, and dilute the berberine concentration with water to 32%. The above extract was mixed with 25 g of shredded tobacco, soaked for 5 hours, dried at 60° C. for 12 hours, pulverized, and passed through a 60-mesh sieve to obtain shredded tobacco berberine. Get 20g shredded tobacco berberine, mix it with woody 15g bentonite, then add 10g ammonium chloride, 15g activated carbon (crushed) and mix, add 40g potassium chlorate. Pulverize and pass through a 60-mesh sieve to obtain the product.

Embodiment 3

[0028] Weigh 200g Coptis rhizome, crush it, add 800mL 60% ethanol, extract at 70°C for 1.5 hours, filter, add 800mL 60% ethanol to the filter residue and continue to extract for 1 hour, combine the filtrates, filter, concentrate under reduced pressure, and dilute the concentration of berberine with water to 45%. The above extract was mixed with 30 g shredded tobacco, soaked for 4 hours, dried at 60° C. for 12 hours, pulverized, and passed through a 60-mesh sieve to obtain shredded tobacco berberine. Take 20g of shredded tobacco berberine, mix with 30g of woody diatomaceous earth, then add 15g of Artemisia annua, 20g of activated carbon (crushed) and mix, and add 45g of potassium permanganate. Pulverize and pass through a 60-mesh sieve to obtain the berberine smoke product.

Abstract

The invention discloses a berberine smoke agent and application thereof. A preparing method of the berberine smoke agent comprises the following steps of (1) utilizing water or ethyl alcohol for extracting berberine from cortex phellodendri or rhizoma coptidis, and conducting filtering and concentration to obtain a plant extracting solution containing berberine; (2) soaking tobacco shreds with theplant extracting solution containing berberine for 2-6 hours, and adsorbing the berberine with the tobacco shreds to obtain tobacco shred berberine; (3) drying or airing the tobacco shred berberine at 60-70 DEG C, smashing the tobacco shred berberine, and making the tobacco shred berberine pass through a 60-mesh sieve; (4) uniformly mixing the sieved tobacco shred berberine with a carrier, then adding a combustion improver, a smoke producing agent and fuel into the mixture for mixing, and conducting smashing and sieving to obtain the berberine smoke agent. The smoke agent can be used for disease and pest control over gray mold, powdery mildew and the like on greenhouse crops, the smoke agent is efficient, capable of saving the time and labor, and convenient to apply, equipment like machines is not needed, complicated steps like water adding are omitted, and the berberine smoke agent particularly has a more special meaning for regions in lack of water.

Description

technical field [0001] The invention relates to a berberine smoke agent and application thereof. The smoke agent can be used for the prevention and control of botrytis cinerea, powdery mildew and other pests in greenhouses. Background technique [0002] Berberine, also known as berberine, is a quaternary ammonium alkaloid isolated from Chinese medicines such as Coptis chinensis, Cortex Phellodendri, and Sangezhen 20 h 18 NO 4 , is the main active ingredient of the above plant antibacterial, yellow needle-like crystals, bitter. It is widely distributed in the plant kingdom, and this product is found in about 4 families and 10 genera. Berberine is effective against fungi such as botrytis cinerea, powdery mildew, and leaf mold, as well as bacteria such as Pseudomonas syringae and Xanthomonas. At present, berberine is mainly registered as wettable powder, soluble and water. In the process of growing vegetables in greenhouses, once gray mold and powdery mildew occur, the clo...
