Even beautiful pineapples must be carefully cared for, as they will be ruined if pests and diseases are not treated!

1. Heart rot and root rot

If you accidentally get infected with them, it is usually because you watered too much or the soil drainage is poor, which makes its roots unable to breathe normally. In addition, it happens to be a season of high temperature and high humidity, so it is more likely to cause these two diseases. Once infected, it will cause great damage to the leaves and roots of the plant, slowing down the growth of the plant, so it is necessary to take timely prevention and control measures.

Prevention and control methods: To prevent this disease, we should first solve the problems of soil, watering and water quality, and then wait until the temperature is higher or it is more humid, and be sure to water it with the corresponding solution 3 times, once a month, so that it can be fundamentally suppressed.

2. Yellowing and withering of leaf tips

3. Scale insects

This is also a relatively common pest and disease. Once infected, the damage is great. It usually sucks the juice from the leaves of the plant, and then some green spots will appear on the leaves, causing poor growth of the leaves. In severe cases, it may also suffer from black spot disease.

Prevention and control methods: After its eggs hatch, if the insects are able to move, we can spray them with some pesticides at this time, so that we can get timely prevention and control. In addition, we can also scrape it off manually with our fingernails, and the effect is also good.

4. Red spider

This pest is very small. If you look at it with the naked eye, you can only see a very tiny red dot. It mainly stays on the back of the leaves or the base of the leaf axils. It reproduces very quickly and can easily cause damage to the seedlings, so it must be prevented and controlled in time.
