Embodiment 1

[0010] Embodiment 1: Control test. Use during the onset of the disease, the mass content of each active ingredient of the compound preparation of the present invention is: 90 grams of carbendazim, 10 grams of melaleucain A, the two are evenly mixed to make a compound preparation, and when in use, dilute 600 times of water to spray on the leaves. Apply 3 times, spray once every 10 days, and use the same spraying method to spray carbendazim as a control. According to the investigation results, the control rate of carbendazim is 58.6%, and the control rate of the preparation of the present invention reaches 81.3%.

Embodiment 2

[0011] Embodiment 2: preventive test. There was a history of disease in the test area in the past, but there was no disease in the year of the test. The mass content of each active ingredient of the compound preparation of the present invention is: 70 grams of carbendazim, and 30 grams of melaleucain A. The two are mixed evenly to make a compound preparation. When in use, it is diluted with water 800 times and sprayed on the leaves for 3 times. Spray once every 10 days, and use the same spraying method to spray carbendazim as a control. According to the investigation results, the morbidity rate of carbendazim prevention is 25.3%, and the morbidity rate of the spraying area of ​​the preparation of the present invention is only 4.6%.

Abstract

The invention relates to a method for controlling watermelon fusarium wilt, and belongs to the field of agricultural production techniques. A compound preparation consisting of carbendazim and oroxylin A is sprayed on leaf surfaces 1-3 times, and the one-time spraying is carried out every 7-15 days, and thus the control effect can be improved, the wax gourd sclerotiniose is effectively controlled, the consumption of effective ingredients is reduced, the pharmaceutical cost is saved, and the environment pollution is reduced.

Description

technical field [0001] The invention relates to a method for preventing and controlling watermelon wilt and belongs to the field of agricultural technology. Background technique [0002] Watermelon wilt, commonly known as "dead seedling disease", is a fungal disease transmitted by soil. The fungus infects young shoots and seedlings, causing rot and slow growth and wilting. The pathogen mainly overwinters in undecomposed organic fertilizer or soil as mycelia, chlamydospores or sclerotia. It can survive in the soil for 6-10 years. The pathogen can be spread through seeds, fertilizers, soil, and watering. Composting and retting are the main ways of spreading. Disease occurrence is closely related to temperature and humidity. The growth temperature of the bacteria is 5-35°C, and the soil temperature of 24-30°C is the optimum temperature for germination and growth of the bacteria. The disease is a soil-borne disease, and the degree of incidence depends on the amount of infe...
