Disease control of cyclamen

Botrytis cinerea

1. Use fungicides such as thiram and dichlorodiphenyltrichloroethane to disinfect the soil or replace it with new soil during planting to prevent the soil from carrying bacteria and spreading diseases.

2. Strengthen indoor ventilation and reduce humidity appropriately; do not water too much and do not water directly on the leaves. Avoid causing wounds during maintenance to prevent the invasion of pathogens.

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

4. Before the disease occurs, spray protective fungicides, such as 600-800 times solution of Green Debao, 800-1000 times solution of 75% Benomyl; when the disease occurs, spray therapeutic fungicides, such as 800-1000 times solution of 70% Thiophanate-methyl, 500-800 times solution of 50% Carbendazim.

Viral diseases

1. Inhibit seed poisoning: Treat with 75% solution for 1 minute, then treat with 10% trisodium phosphate for 15 minutes, wash the solution on the surface of the seeds with distilled water, place in warm water to cool naturally for 24 hours, and sow in sterilized soil. Seed detoxification: Place the seeds in a 40% polyethylene glycol solution and treat them at a constant temperature of 38.5℃ for 48 hours. The seed detoxification rate can reach 77.7%.

2. Use bulbs, leaf tips, and petioles as explants for tissue culture seedlings to reduce the virus rate.

3. The planting soil must be disinfected or sterilized vermiculite, perlite sand, etc. must be used.

Root rot

It is a disease in the seedling stage. The roots are waterlogged, softened and rotted, and the diseased seedlings wilt, turn yellow and die.

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 potassium permanganate solution to disinfect the soil.

3. Strengthen ventilation and control humidity; release air appropriately to harden the seedlings and enhance their resistance.

4. In the early stage of the disease, you can use 72.2% Prolike aqueous solution, 50% Toluidine, and 40% Root Rot Ning 1000 times liquid for spraying or root irrigation for prevention and control.

Bacterial soft rot

Water-soaked spots appear on the leaves, which then become soft and rotten, with white bacteria exuding from them, and the plants wilt and die.

Prevention and control measures

1. Remove diseased leaves and remove diseased plants.

2. Control watering and pay attention to ventilation.

3. Use 50% thiophanate-methyl wettable powder (WP) at 1000-2000 times dilution for spraying for prevention and control.

anthrax

Damages leaves and peduncles. Brown circular spots appear in the early stage, black spots appear in the later stage, and red sticky masses overflow when it is wet.

Prevention and control measures

1. Cut off diseased leaves in time.

2. Enhance ventilation and light transmission and reduce humidity.

3. You can use 800-1000 times the liquid of 60% anthrax thiophanate and 70% methyl thiophanate wettable powder for prevention and control.
