How to deal with potted duck feet

Duck foot wood is not only an ornamental plant, it has a certain impact on the purification of household air, it can absorb nicotine and other harmful substances and transformed into their own substances, is a beneficial plant. But recently, I found that the branches and leaves of my duck feet secrete sticky substances, and my hands can feel sticky, just like glue.

Checked on the Internet, this is the harm of scale insects, mucus is the secretion of scale insects, the small yellow spot protruding on the leaves is the wax of scale insects. Scale insects are important pests of woody flowers and plants. There are more than ten kinds of pests such as shield scale, wax scale, cotton scale and pink scale. Light ones cause chlorotic spots on leaves, obvious insect spots, loss of ornamental value, dry leaves and branches, and weak tree potential. Serious ones can cause tree death.

The pink scale can also secrete a large amount of honeydew, resulting in the occurrence of soot disease and soot-like leaves. Wax shell film makes many insecticides powerless. One kind of quick killing EC is organophosphorus insecticide. Its most important feature is that it can kill the lower insect body and the eggs laid through the wax shell or wax quilt covered by the body surface of scale insects. The spraying time is not limited by insect state and can be used at any time when scale insects occur.

Quick killing EC has a very high control effect on scale insects. Scale insects can be well controlled by spraying once or twice a year, and scale insects can be basically wiped out after continuous use for 2 to 3 years. But now only one spray of the long worm is not cost-effective, and it will pollute the environment. It is suggested to find a piece of bamboo and scrape it off manually, the effect is better.

So I had to cut off the leaves with slime and insects and spray some diluted vinegar every day. I found that a bug had to be scraped off, and the battle to defend the duck foot wood had just begun.

For the phenomenon of a small number of worms, you can wipe it off with cotton dipped in diluted alcohol, and a large number of garlic can be sprayed with water (chopped garlic). It can also be sprayed with about 20 red chili peppers (the hotter the chili is, the better). Spray with hot water in a 500 ml cola bottle. If you like smoking, you can use cut tobacco to soak (when the liquid turns dark brown). The effect is very good. Pay attention to spraying to the back of the leaves. Spray it on the worm, but it won't work if you don't get it. In addition, you can bury 3% carbofuran in the basin soil, or you can dip some dichlorvos solution with cotton wool, insert it in the basin soil, and cover it with a plastic bag, and all the worms will die in less than a day.

This insect is called the duck foot tree star room wood lice, occurs generation overlap (adult larva egg), is more difficult to control, medicament has deltamethrin 3000 to 4000 times liquid and omethoate 1000 times liquid, spray three times in a row, the interval 7-10 days, mainly sprays the new tip. The phototaxis of adults is strong, and light inducement can also be used to avoid the harm that it continues to lay eggs.

If you have "powder media" or "aphids", you can spend 2 yuan to buy a sprinkler (the kind that emits foggy water droplets and the kind that the barber sprays on your head when you get a haircut). Go to the place where you sell pesticides or flowers and buy a small packet of aphid medicine and spray it with water. If not, just get a brush or brush, dip it in salt water or soapy water, just brush it down, and brush it twice more.

1. The insect pests are mainly caused by shell insects, which are sprayed with 1000 times of omethoate EC.

2. Red spiders, thrips and leaf moths can be sprayed with 3000 times of permethrin EC to harm the leaves of goose palm wood.

Bacterial treatment:

If there is harm to leaf spot and anthracnose, it can be sprayed with 1000 times of acetic acid solution of 10% antibacterial agent 01.
