Embodiment 1

[0008] Embodiment 1: Indoor bacteriostatic activity assay of monensin sodium to fungus

[0009] The phytopathogenic fungi used in this experiment were strains stored at 4°C in the laboratory. The mycelial growth rate method was used. The medium used for all phytopathogenic fungi in the laboratory was potato agar dextrose medium (PDA for short). PDA medium formula: potato (peeled) 200g, glucose 20g, agar 15g, distilled water 1000mL.

[0010] PDA medium preparation method: wash and peel the potatoes, weigh 200g and cut into small pieces, add water and boil until it can be punctured by a glass rod, filter with four layers of gauze, add distilled water in a beaker To 1000 mL, add 15-20 g of agar according to the needs of the experiment, add 20 g of glucose, stir to dissolve it fully, then divide it into Erlenmeyer flasks, sterilize at 121°C for 20 minutes, and cool down for later use.

Abstract

The invention discloses a new application of a feed additive monensin sodium in preventing and treating fruit postharvest rot-causing fungi and agricultural plant pathogenic fungi, and belongs to the field of agricultural bactericides. The monensin sodium provided by the invention has the advantages that the monensin sodium can be used for treating fruit postharvest rot-causing fungi such as botrytis cinerea, penicillium expansum ACCC30898, rhizopus stolonifer CICC 40327, monilinia coerulea ACCC 36263, aspergillus flavus ACCC32601 and the like; the compound has obvious bacteriostatic or bactericidal activity on various plant pathogenic fungi such as rhizoctonia solani, sclerotinia sclerotiorum, fusarium graminearum, magnaporthe oryzae, phytophthora capsici and potato late blight, and can be further developed and applied in the field of agricultural fungal disease control.

Description

technical field [0001] The invention relates to a new antibacterial application of monensin sodium and belongs to the field of agricultural fungicides. Background technique [0002] Plant fungal diseases seriously threaten the healthy development of agriculture and food safety. The annual grain loss caused by plant diseases has exceeded 11% of the output. For example, paddy fields in my country are affected by rice sheath blight, which causes a loss of 6 million tons of grain every year; wheat is affected by scab, causing a 10% to 30% reduction in production every year; Fresh fruits and vegetables are rotted due to postharvest fungi, and the proportion in developing countries is even higher, reaching 40% to 50%. In my country, the total output of perishable characteristic fruits reaches 116 million tons, and the postharvest loss is 25% to 30%, about 70 billion yuan. After being infected by pathogenic microorganisms, the rotten grains, fruits and vegetables have a sharp drop...
