Abstract

The invention discloses a reagent for preventing and treating tobacco wildfire and a preparation method thereof. The reagent comprises the following components: benziothiazolinone, copper abietate, kasugamycin, zinc thiazole and oxine-copper. The reagent prepared by the method of the invention not only has a good prevention and treatment effect on tobacco wildfire, but also can delay the generation of drug resistance, and does not pollute the soil environment at the same time.

Description

technical field [0001] The invention relates to the technical field of tobacco plant protection, in particular to a medicament for preventing and treating tobacco wildfire disease and a preparation method thereof. Background technique [0002] Tobacco, Latin scientific name: Nicotianatabacum, is an important economic crop. Tobacco is an annual herbaceous plant in the family Solanaceae, and there are about 60 species of Nicotiana. Tobacco wildfire disease is caused by the bacterium Pseudomonas syringae pv. tobacco. The germs overwinter on the sick body and are spread by wind, rain or insects. The optimum temperature for wildfire disease to occur is 28-32°C. Heavy rainfall and high humidity, especially storms are not only conducive to the spread of bacteria, but also cause wounds on the tobacco plants, resulting in bacterial invasion; after the tobacco field is hit by hail, a large number of holes are formed on the leaves, and germs can invade from the wounds, causing wildf...
