Embodiment

[0049] 1. Bacteria fermentation:

[0050] The cryopreserved Aspergillus sp. LW1 was recovered in the plate medium, and the culture temperature was 28 °C, and then the bacteria were inoculated into the fermentation medium with an inoculation loop in the ultra-clean workbench, and cultivated at 180 rpm and 28 ° C. 7d.

[0051] The plate medium was prepared according to the following steps: 6.0 g of potato flour, 20.0 g of glucose, and 20.0 g of agar were dissolved in 1 L of deionized water, and autoclaved at 121° C. for 30 min. The fermentation medium was prepared according to the following steps: Dissolve 20 g of glucose, 5 g of yeast extract powder, 10 g of soy peptone, and 30 g of sea salt in 1 liter of deionized water, adjust the pH to 7.5 with 1 M HCl or 1 M NaOH, and sterilize by autoclaving at 121 °C for 30 min.

[0052] Fermentation was carried out in 1000ml conical flasks, each fermenting 400ml, a total of 25 bottles were fermented, and the fermentation volume was 10L....

Abstract

The invention relates to the field of compound preparation, in particular to an application of dimethyl xanthoxylin in resisting plant pathogenic fungi. The dimethyl xanthoxylin is applied to resistance of plant pathogenic fungi. The dimethyl xanthoxylin has the activity of resisting plant pathogenic fungi, and can be applied to resistance of the plant pathogenic fungi, so that the growth of the plant pathogenic fungi in crops or ecological environments is inhibited, and the harm of plant diseases to the crops and the ecological environments is solved.

Description

technical field [0001] The invention relates to the field of compound preparation, in particular to the application of a kind of dimethyl penicillin in anti-phytopathogenic fungi. Background technique [0002] Phytopathogenic fungi refer to fungi that can parasitize plants and cause plant diseases, and are an important source of infection for plant diseases. Almost eighty percent of all plant invasive diseases are caused by fungi, and every plant can be affected by several or even dozens of fungi. Such as wheat rust, rice blast, vegetable soft rot, apple tree rot are all fungal diseases. [0003] Fungal diseases will reduce crop yields and quality of agricultural products, thereby causing serious economic losses to the production of agricultural products. Some fungal diseases may even produce toxins in agricultural products, endangering the health of humans and animals, such as scab-infected wheat grains. Toxins and female-like toxins can cause vomiting, diarrhea and other...
