Disease control of Cyclamen

Botrytis cinerea

1. When planting, use fungicides, such as fumeishuang, dikesong, etc. to disinfect the soil or replace it with new soil, so as to avoid the spread of soil borne diseases.

2. Strengthen indoor ventilation and properly reduce humidity; do not water too much, and do not directly water to the leaves, avoid causing wounds during maintenance management, so as to prevent the invasion of bacteria.

3. It is necessary to remove the diseased plants, leaves and reduce the source of pathogens in time.

4. Spray protective fungicides before the onset of the disease, such as 600-800 times of green Debao, 800-1000 times of chlorothalonil, 75%; spray therapeutic fungicides when the onset of the disease, such as 70 & amp; methyltobuzine, 800-1000 times, 50% carbendazine, 500-800 times.

1. Inhibition of seed toxicity: 75% for 1min, then 10% trisodium phosphate for 15min, distilled water for cleaning the solution on the seed surface, then placed in warm water for natural cooling for 24h, and seeded in sterile soil. Seed detoxification: the detoxification rate of seeds can reach 77.7% when the seeds are placed in 40% polyethylene glycol solution and treated at 38.5 ℃ for 48h.

2. Using corm, leaf tip and petiole as explants to culture plantlets to reduce the virus rate.

3. The planting soil should be disinfected or vermiculite and perlite sand should be used.

Root rot disease

it is a disease of seedling stage, the root is water stained, softened and rotted, and the disease seedling wilts, withers and dies.

Prevention and control measures

1. Soak the seeds in 0.1% copper sulfate solution for half an hour for disinfection.

2. Before sowing, spray 1800-2000 times solution of potassium permanganate to disinfect the soil.

3. Strengthen ventilation and control humidity; release air and refine seedlings properly to enhance resistance.

4. In the early stage of the disease, 72.2% pulicol, 50% likujing and 40% rootfuning 1000 times solution can be used for spraying or root irrigation.

Bacterial soft rot

leaves produce water stains, and then soft rot, remove white bacterial overflow, and wither and die.

Prevention and control measures

1. Remove the diseased leaves and plant.

2. Control watering and pay attention to ventilation.

3, with 50% of "Xiao Ling Ling wettable powder" 1000-2000 times liquid spray control.

Anthracnose

harmful to leaves and pedicels. In the early stage, there were brown round spots, and in the later stage, there were small black spots. When it was wet, there was red mucus.

Preventive measures

1. Cut off the diseased leaves in time.

2. Strengthen ventilation and light transmission to reduce humidity.

3. It can be controlled with 60% anthrax Fumei and 70% methyltobujin wettable powder 800-1000 times.
