Embodiment 1

[0036] 1. Experimental materials

[0037] Sodium diethyldithiocarbamate was purchased from Sigma. Weigh 2.25g of sodium diethyldithiocarbamate in 100ml of distilled water to prepare a 0.1M mother liquor, 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.

Abstract

The invention discloses application of sodium diethyldithiocarbamate in preparing a bactericide for preventing and treating plant diseases caused by plant pathogenic bacteria, and the indoor toxicitytest proves that the sodium diethyldithiocarbamate has good inhibitory activity on plant pathogenic fungi. The traditional bactericide has large pollution to the environment and high residue, and directly threatens food safety. The use of a large amount of bactericide leads to the enhancement of the drug resistance of pathogenic bacteria, and the invention provides the use of sodium diethyldithiocarbamate as the bactericide for the first time, which has the advantages of high efficiency and low toxicity, and is suitable for the requirement of chemical control of plant diseases. The sodium diethyldithiocarbamate is a degradable, pollution-free and environment-friendly small molecular compound and drug resistance is poor, which is safe to non-target organisms and human and livestock, the high quality of agricultural products and fruits and vegetables can be ensured, and meets the requirement of sustainable development, and has wide research and market application prospects.

Description

technical field [0001] The invention relates to compounds with fungicidal activity, in particular to the application of sodium diethyldithiocarbamate in the preparation of fungicides for preventing and treating plant diseases caused by plant pathogenic bacteria. Background technique [0002] Agriculture has always been the lifeblood of our national economy, and the development of agriculture is directly related to the stability and development of society. However, plant diseases seriously affect crop yields and farmers' income, which in turn threatens food security and poses great challenges to agricultural production. It is estimated that plant diseases cause a reduction of more than 10% in global food and other crop production, and cause an annual economic loss of about 100 billion U.S. dollars. 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 certain exten...
