Diseases and Pests of Medal Flower and Their Control

Common diseases and prevention methods of medal flowers

Leaf spot

The most common disease of medallion flower is leaf spot. Leaf spot disease is actually best treated by prevention, and a combination of prevention and treatment is better. The best way is to take preventive measures before the disease occurs. In daily management, good management and reasonable maintenance are necessary to ensure the healthy and vigorous growth of the medal flower. You can also use 1000 times diluted 25% carbendazim for foliar spraying to prevent leaf spot disease. If leaf spot disease breaks out on the medallion, you can spray the leaves with 800 times diluted 25% carbendazim or 800 times diluted thiophanate-methyl, once every 7 to 10 days, and spray 2-3 times in a row. The effect is very obvious.

Botrytis cinerea

Gray mold can also harm the health of medallion flowers. When gray mold occurs in the medal flower, it can be treated by spraying with 1000 times diluted 70% thiophanate methyl or 1:1:100 Bordeaux mixture.

Common Pests and Control Methods of Medal Flower

aphid

Aphids are natural enemies of most plants, and they can also cause considerable harm to medallion flowers. When the medal flower is attacked by aphids, you can catch the insects manually when there are fewer insects, or you can use 2000 times of diazinon solution or 1000 times of dichlorvos solution to spray and treat it, once every 10 to 15 days.

Red Spider

Red spider mites are also a common pest that harms medallion flowers. Red spider mites are more likely to break out in hot and humid weather. In daily management, ventilate more, maintain air circulation, and do not give red spider mites the opportunity to reproduce. When red spider mites are discovered, you can use 1500 times diluted 40% oxydemeton-methyl emulsifiable concentrate to spray them.

Black red mite

Black red mites are also a common pest of medallion flowers. Black red mites are piercing-sucking pests and can be treated by spraying with imidacloprid and its modified formulations.
