Embodiment 1

[0036] 1. Experimental materials

[0037] Diclofenac sodium was purchased from Sigma. Weigh 3.18g of diclofenac sodium into 100ml of dimethyl sulfoxide to prepare a 0.1M mother solution, filter and sterilize and store at 4°C until use.

[0038] In this experiment, the plant pathogenic bacteria were stored in a refrigerator at 4°C, and the medium used was potato dextrose medium (PDA for short).

[0039] PDA medium formula: potato (peeled) 200g, glucose 20g, agar 15g, tap water 1000ml, natural pH.

[0040] Preparation method: wash and peel the potatoes, weigh 200g and cut into small pieces, add water and boil (boil for 15-20 minutes), filter in a beaker with eight layers of gauze, add 15-20g of agar according to the needs of the experiment, add 20g of glucose, Stir evenly, fully dissolve, then cool slightly to make up water to 1000ml, dispense and sterilize at 121°C for 20 minutes, cool and set aside.

[0041] 2. Experimental method

[0042] using the growth rate method.

Abstract

The invention discloses the application of diclofenac sodium in preparation of a fungicide used for controlling plant diseases caused by plant pathogens. Through indoor toxicity measurement, it is proved that diclofenac sodium has good inhibitory activity against the plant pathogens. Diclofenac sodium is used as the fungicide for the first time, has the advantages of low toxicity and high efficiency, and is suitable for chemical control of plant diseases. Traditional chemical fungicides have high pollution to the environment and high residues and pose a serious threat to food safety. Diclofenac sodium is an environmentally friendly small molecule compound and is degradable and free of pollution, the drug resistance of plant pathogenic fungi is low, and the diclofenac sodium is safe to non-target organisms, human beings and livestock. The high quality of agricultural products, fruits and vegetables can be ensured, the requirements of sustainable development are met, and the diclofenac sodium has wide research and market application prospects.

Description

technical field [0001] The invention belongs to the technical field of agricultural biology and relates to bactericidal active compounds, in particular to the application of diclofenac sodium in the preparation of fungicides for preventing and treating plant diseases caused by plant pathogenic bacteria. Background technique [0002] In the new century, problems such as resource shortage, environmental pollution, ecological damage and frequent natural disasters have become increasingly prominent, seriously hindering the sustainable development of agriculture, and agricultural production is therefore under unprecedented pressure. According to the estimates of the Food and Agriculture Organization of the United Nations, the annual loss of grain and cotton production in the world is more than 10% due to diseases. Plant diseases can not only reduce the yield of crops, but also seriously threaten the quality and safety of agricultural products and their international trade to a ce...
