Abstract

The invention discloses a preparation method of a compound drug for preventing and treating a rhizopus disease of lettuce. The preparation method comprises steps as follows: A, a mixture of monopotassium phosphate and calcium chloride in the ratio being 2:1, sodium polyacrylate, 72% cymoxanil*mancozeb wettable powder diluted for 600 times, an oxazolone amine preparation, appendiculate cremastra pseudobulb, butanol and sodium alginate are prepared; B, the 72% cymoxanil*mancozeb wettable powder diluted for 600 times and appendiculate cremastra pseudobulb are treated with an alcohol extraction method, and a traditional Chinese medicine solution is obtained; C, sodium alginate is added to the traditional Chinese medicine solution in the step B and sufficiently dissolved for standby use; D, the mixture of monopotassium phosphate and calcium chloride in the ratio being 2:1, sodium polyacrylate and a mixture obtained from the step C are uniformly stirred, butanol is added, water is added until the mixture is sufficiently dissolved, a stock solution is obtained and subjected to ultraviolet disinfection, and the drug for preventing and treating the rhizopus disease of the lettuce is obtained. The preparation method is simple, a prepared product is simple in proportioning and convenient to use, and the efficacy is improved by 15%-19% in comparison with that of commercially available drugs for preventing and treating damping-off.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of agricultural product diseases, and in particular relates to a preparation method of a compound drug for preventing and treating lettuce root disease Background technique [0002] Moldy root disease of lettuce is caused by the fungus Pythium melonis of the flagellate subphylum. The fungus survives the winter in the soil with oospores along with the diseased residue, and can live in saprophytic life. When the conditions are suitable, the oospores germinate, produce germ tubes, and directly invade the young buds, or the top of the germ tube expands to form sporangia, and the zoospores are spread to the seedlings by rain or irrigation water, and invade from the base of the stem. Mildew root disease is one of the important diseases of lettuce seedlings. It is distributed all over the country. It is often caused by unsuitable temperature and humidity and extensive management during th...
