1、 Common diseases

1. Scab disease

Features: this disease mainly erodes the branches and stems of flowers. There will be many scattered or aggregated brown dots on it, and the epidermis near the dots will be concave

Treatment:

(1) If it is a newly ill keel flower, you can clean and burn those small brown spots with a sharp knife, and smear the sick place with Bordeaux slurry

(2) Spray medicine on the disease site and the surrounding branches and leaves every other week, and then spray it every two weeks in the later stage

2. Anthrax

Features: it mainly invades the fleshy stems of flowers. The spots formed by this disease are large, with a diameter of 2-3cm. They are semicircular or oval in shape. The color is brown and will turn gray white in the later stage

Treatment:

(1) Usually pay more attention. If you find that you are sick, you should cut off the diseased stem and burn it. Apply with copper oxychloride solvent every 5 days

(2) If you want to reproduce, you should choose branches that are not sick, soak them with 70% tobuzin and 75% chlorothalonil for 30 minutes, and then dry them

(3) If it is not long after the onset, use 30% copper oxychloride to fuse 70% mancozeb, apply it every ten days and spray it 2-3 times

2、 Common pests

1. The keel flower is rarely threatened by insects. If it gives birth to white gold needle worm, grub and mole cricket, it can be effectively stopped by watering the root with a thousand times of insect medicine

2. If the ventilation in the room is not very good, it is likely to produce red spiders, which will harm the top of the plant. If you find that the top is reddish brown and has spider webs, you can use enemy killing to deal with it

3. If there are aphids or scale insects, you can melt the washing powder and spray it. Because it is an alkaline substance, it will alkalize the flowerpot, so it is best to wrap the flowerpot in a plastic bag before spraying. Washing powder can block the pores of pests, making them unable to breathe and die. After killing insects, wash the leaves of the flowers

4. If a snail is found, it will eat the stems and leaves of the flower and can catch it by itself. Be sure to note that if you accidentally remove the branches and leaves of the flower and flow out the juice, don't get it into the import. Wash your hands quickly after treatment, otherwise you will feel numb
