Prevention and Treatment Methods for Jasmine Leaf Spot Disease
Compared to the common cultivation content of jasmine in most people's flower clinics, the prevention and treatment methods for jasmine leaf spot disease will be introduced to everyone in the following sections.
Symptoms of Jasmine Leaf Spot Disease: It affects the leaves, initially producing light brown spots, which then spread to the surroundings. The affected area becomes thin, with irregular, yellow-brown spots, surrounded by a thin brown line, clearly distinguishing it from healthy parts. In the later stage, small black dots appear on the spots, and in severe cases, it can cause perforation or leaf drop.
Characteristics of Jasmine Leaf Spot Disease: This disease is a fungal disease, with the pathogen overwintering in the affected parts or fallen leaves, and spores being spread by wind and rain. The disease starts in May to June and continues until August to September. Excessive rain in summer and stagnant humidity can easily trigger the disease.
Prevention and Treatment Methods for Jasmine Leaf Spot Disease:
1. Remove affected leaves promptly and incinerate them.
2. Apply more phosphorus and potassium fertilizers to promote healthy plant growth and enhance disease resistance.
3. Spray once with a 27% copper高尚 suspension or 12% green copper emulsion diluted 600 times, or a 1:1:160 Bordeaux mixture before the disease occurs. After the disease occurs, spray with a 50% methylethylthiosemicarbazone wettable powder diluted 600 times, or a 40% carbendazim suspension diluted 500 times, a 25% benomyl·cycloheximide emulsion diluted 800 times, a 50% methylthiophanate·sulfur suspension diluted 800 times, or a 50% ridomil wettable powder diluted 1000 times. Repeat every 7 to 10 days for 2 to 3 treatments.
