Pest control of pineapple with colored leaves

Heart rot and root rot

If it is the base of the blade tube slowly softening or even rotten, it is very likely to change the heart rot. There will also be a bad smell in the air, and if the leaf or tube is taken out, it will soon fall back to itself. If the root rot, the whole root tip will slowly rot, and the lateral roots will not grow out, so if it is found that the plant's ability to absorb water and fertilizer is too poor, and the plant grows slowly, root rot may occur.

At ordinary times, in addition to paying attention to the problem of watering, we should also use specific medications to prevent them from getting sick in times of high temperature. Once a month for three months.

Yellow leaves and withered leaves

If the pursuit points in the air do not meet the requirements, it is likely to cause their leaves to change color. Not only this, but the application of too much fertilizer or too many times will also have this consequence. This kind of plant is very intolerant to cold, and freezing injury will occur if it is not on 5 ℃ in winter. If the freezing injury is serious, it may die directly.

Insect pest

Scale insect

This kind of insect is a very common pest. Although they are small, they are quite lethal. After they absorb the sap of the leaves, there will be spots on the leaves, do not ignore these wounds, because the mucus on the wounds attached to the leaves for a long time will lead to black mold. If such insects appear, the best time to control them is when the bugs have not yet thickened, and then you can spray them with special reagents to control them.

Red spider

This kind of disease and insect is also very common, it is more difficult to see with the naked eye, but also can see those little red dots. But do not underestimate them, the proliferation of this pest is very fast, especially in the relatively dry season, if found, to deal with this situation immediately. This can directly choose a special insecticide.
