Embodiment 1

[0012] A crop fungal disease synergistic composition containing comfrey extract and pesticides, comprising a component A and a component B, the component A is a traditional Chinese medicine comfrey extract, and the component B is composed of prochloraz Medicine composition; wherein the A component is 50 grams, and the B component is 1 gram.

[0013] The preparation method of the composition of the crop fungal disease synergistic composition containing comfrey extract and pesticide includes the following steps: each component is weighed according to the above weight, and the component A is first dissolved in 1 volume Then use 8 times the volume of 1-2wt% NaOH to completely dissolve the absolute ethanol, and mix the extract with the B component to make a synergistic composition of traditional Chinese medicine and pesticides.

Embodiment 2

[0015] A crop fungal disease synergistic composition containing comfrey extract and pesticides, comprising a component A and a component B, the component A is a traditional Chinese medicine comfrey extract, and the component B is composed of prochloraz Medicine composition; wherein the A component is 200 grams, and the B component is 1 gram.

[0016] The crop fungal disease synergistic composition containing comfrey extract and pesticide comprises the following steps: each component is weighed according to the above-mentioned weight, and the A component Chinese medicine comfrey extract is 10:1, The A component is first dissolved in 1 volume of anhydrous ethanol, and then it is completely dissolved with 8 volumes of 1-2wt% NaOH, and the extract is mixed with the B component to prepare traditional Chinese medicines and pesticides The synergistic composition.

Embodiment 3

[0018] The composition in Example 1 or 2 was selected to detect its effect on Sclerotinia sclerotiorum ( Sclerotinia sclerotiorum ), Banana Fusarium Wilt ( Fusariun oxysporun ), Aspergillus flavus ( Aspergillus flavus ), Botrytis cinerea ( Botrytis cinerea ) And other crop pathogenic fungi growth rate inhibition. On the ultra-clean workbench, first inoculate Fujian isolated sclerotinia, banana fusarium wilt, aspergillus, and gray mold on the PDA solid medium, and cultivate in the dark for 48-72 hours at 25°C. On the ultra-clean workbench, inoculate the cultivated 5mm small plates of Sclerotinia sclerotiorum, Banana Fusarium wilt, Aspergillus flavus, and Botrytis cinerea into the PDA medium (containing the 1000-fold dilution of Example 1 or 2) The growth rate of pathogenic bacteria was calculated by the cross method after 48-72 hours of dark culture at a temperature of 25°C. The growth rate of the PDA medium without the composition was used as the control. The growth rate s...

Abstract

The invention belongs to the technical field of plant protection and particularly relates to a lithospermum extract and pesticide-containing synergistic composition for treating crop fungal diseases.The composition comprises a component A and a component B. The component A is lithospermum extract. The component B is a prochloraz original drug. The component A and the component B are mixed according to a weight ratio of 50: 1 to 200: 1. Through the synergistic effect of the various components, the lithospermum extract and pesticide-containing synergistic composition belonging to the fungal pesticide can be used for preventing and treating crop fungal diseases.

Description

Technical field [0001] The invention belongs to the technical field of plant protection, and specifically relates to a crop fungal disease synergistic composition containing comfrey extract and pesticides. Background technique [0002] Comfrey was first published in "Shen Nong's Materia Medica" and is a perennial herb of the Boraginaceae family. The comfrey included in the first edition of Pharmacopoeia of the People's Republic of China in 2010 is the dried root of the comfrey Arnebia euchroma (Royle) Johnst. or Arnebia guttata Bunge of the comfrey family.
