Embodiment Construction

[0033] 1. Research on the antibacterial mechanism of Penicillium antagonism P19

[0034] The antagonistic bacteria Penicillium funicoli with the best control effect on potato black mole was screened out by plate confrontation method, and the antibacterial mechanism of Penicillium funiculosa was studied. Pick the hyphae on the plate confrontation culture inhibition zone or the hyphae when the early Penicillium fungus and the potato black mole bacteria first contact, make temporary slides to observe and take pictures under the microscope.

[0035] attached Figure 1-8 They are the microscopic morphological diagrams of the potato nevus pathogen under the action of the antagonistic Penicillium fungus for 5 to 10 days, respectively. It can be seen generally that the antagonistic Penicillium fungus does have an inhibitory effect on the potato nevus pathogen. Potato nevus fungus and the antagonist Penicillium fungus began to contact and interact on the 5th day of confrontation cultu...

Abstract

The invention relates to the technical field of antibiological inoculants for treating potato black scurf, in particular to application of penicillium funiculosum in preparing a drug for treating or preventing the potato black scurf. The application has the advantages that the effect of penicillium funiculosum preventing and treating the potato black scurf is obvious, and the defect of preventing and treating of the potato black scurf in the traditional method is overcome; the adopted bacteria strains are widely distributed, the obtaining is easy, and the penicillium funiculosum is suitable for large-scale popularization.

Description

Technical field: [0001] The invention relates to the technical field of biocontrol fungi for treating potato black mole, in particular to the application of Penicillium fungus in the preparation of medicines for treating or preventing potato black mole. Background technique: [0002] Potato black mole (Rhizoctonia solani), its pathogenic bacteria is Rhizoctonia solani, so it is also called Rhizoctonia solani, stem rot, Rhizoctonia canker, black rough skin disease, which is caused by diseased seed potatoes and Soilborne diseases. Rhizoctonia solani is widely distributed, has strong adaptability and fast growth, and is very harmful to potato growth. Once potatoes grown in diseased soil are infected by pathogens, their roots and stems will be harmed, which in turn will affect the potato pieces. The diseased potato pieces are obviously smaller than the healthy potato pieces, which will bring a greater impact on the normal growth of crops and farmers’ economic income. loss. Th...
