Prevention and control of snapdragon diseases

1. Grey mold

Gray mold is an important disease of snapdragon cultivated in greenhouse. The stems, leaves and flowers of the plant can be damaged, mainly flowers.

[Solution] At the beginning of the disease, choose 70% thiophanate-methyl WP 1000 times solution, or 50% carbendazim WP 800 times solution spray control. Spray once every 10~15 days, spray 2~3 times continuously.

2. Scorched disease

[Hazard characteristics] High temperature, rainy and high humidity are conducive to the occurrence of snapdragon scorch disease. The middle part of the disease spot on the leaf is gray, the edge is brown and slightly raised, the diameter of the disease spot can develop from about 1 mm to 15 mm, and concentric ring longitude and longitude appear. The disease spot on the stem mainly occurs at the base, the middle part of the disease spot is slightly depressed, and the rest is similar to the disease spot on the leaf. When the disease is serious, the leaves fall early and the plants are short.

[Solution] If the disease is found, spray 70% thiophanate-methyl 1000 times solution or 65% zebrazine wettable powder 500 times solution in time for prevention and control, spray once every 10 days, continuous spray 2~3 times can effectively control the disease.

3. Grass rust

[Hazard characteristics] Grass rust mainly damages snapdragon leaves, tender stems and calyx.

[Solution] In the early stage of the disease, spray 15% triadimefon WP 2000 times or 65% zineb WP 500 times.

4. Leaf blight

[Hazard characteristics] Leaf blight mainly occurs in the leaves and stems of snapdragon.

[Solution] At the beginning of the disease, spray the same amount of Bordeaux mixture, or 65% Zineb WP 600 times solution, or 50% Lepent WP 2000~2500 times solution.

5. Stem rot

[Harm characteristics] Stem rot mainly damages the stems and roots of snapdragon. At the beginning of the disease, pale brown spots appeared on the rhizome, and the plants died when they were serious.

[Solution] At the early stage of disease, spray 200~400 times solution of 40% ethyl phosphine aluminum wettable powder to the affected part, or irrigate the root of the plant with 1000 times solution of 50% Dijundan wettable powder.

6. Seedling rot

[Hazard characteristics] Seedling rot mainly damages snapdragon seedlings. At the beginning of the disease, the base or root of the seedlings near the soil surface is water-stained, and finally decays, resulting in the whole plant lodging or wilting and dying.

[Solution] At the beginning of the disease, spray 50% carbendazim WP 800 times or 75% chlorothalonil WP 800 times.
