Want to find out how to cure plant diseases?

Plant protection products are those that are used to prevent and treat plant diseases. We know it is a topic that worries many, so we want to give you some suggestions for their use.

What problem do your plants have?

To know which product to choose, we must first identify their problem. These are the most common:

  • Insects – They bite or pierce leaves, stems, and fruits, they can cause serious damage up to the death of the plant. They usually hide on the underside of the leaves, so they can be spotted easily enough. To eliminate or prevent their appearance, an insecticide is needed.
  • Mushrooms – They grow on plants, from which they derive nourishment. The first indication of their appearance is spots and discolorations of leaves and stems. To treat them, you will need a fungicide.
  • Lack or excess of nutrients – It is signaled by a change of color in the leaves, which lose color or turn yellow. To solve the problem, you will need fertilizer or a deficiency corrector.
  • Excess or lack of water or sun exposure. If you have not found pests or spots, the leaves have good color, think if your plants may need more or less watering, more or less light.

We insist on this point: it is essential to identify the problem.

To understand how to treat plant diseases, it is useless to apply an insecticide to a plant with mushrooms or vice versa.

The kit of basic plant protection products

Suppose we have ruled out an excess or lack of irrigation, the plant is receiving the light it needs, and we regularly fertilize it. In this case, an insecticide and a fungicide would be sufficient, as well as some specific products that we will discuss later.

It is important to know that most of these products have both a preventive and curative function, and it is always better, we always emphasize, to try to prevent than to cure. Let’s take an example, it’s summer and, in some areas, we can suffer from torrential rains. This is a perfect situation for the appearance of mushrooms because they find all the necessary conditions for development: heat and humidity.

After the rains, it would be good to apply a fungicide to our plants, as prevention. In this way, we will prevent the spores of the mushrooms from finding a suitable environment for their growth.

The same goes for insecticides. Have you noticed that in the instructions they normally recommend repeating the application after a few days? This is because many of them act on adult insects, but not on the eggs that these may have deposited on plants. The eggs will hatch after a few days, giving rise to a new generation that will continue to cause problems.

We said before that, apart from fungicides and insecticides, other specific products should be part of our dressing kit for plants:

  • A slug, a product against slugs and slugs. An inevitable element, although they usually do not appear on the terraces or balconies, unless they arrive as guests of some plants.
  • If you have geraniums, we recommend that you keep a specific insecticide against butterfly larvae on hand which usually attacks them. It is a specific parasite (also called the geranium butterfly ) that attacks only this type of plant, so we must be prepared if we want it to continue growing healthy and vigorous.
  • A corrector of ferric chlorosis, a lack of iron that occurs in hydrangeas, camellias, gardenias, and hibiscus, among others. The leaves begin to turn yellow, then to shrivel until they fall off.
  • Calcium-rich fertilizer for your tomatoes, especially if they have already suffered from top rot, such as the one shown in the photo.

How to apply plant protection products?

Most of the products are presented in powder form to be diluted or, directly, in liquid form. To apply them, you will need a sprayer or sprayer that will allow you to distribute them evenly on leaves and stems.

If you have few plants in the house, a small model, such as sprayers for cleaning products, will suffice. However, we strongly recommend that you switch to pressure sprayer models. They are very comfortable because thanks to the lever, the liquid will have enough pressure to exit without having to operate it continuously. They usually have an adjustable nozzle, so it is possible to evenly vaporize the products on the plants.

Larger sprayers also include a spear, which will prevent you from stooping or touching the plants. In addition to convenience, it is also important to stay as far away from the product you are applying as possible, as some can cause breathing problems. We don’t want to frighten you, but we recommend that you always read the manufacturer’s instructions carefully and take all necessary precautions to apply them in total safety.

We conclude with other tips: try to apply plant protection products in the morning or the evening, when the sun does not directly hit the plants. It will be much more effective and convenient, especially for ecological products: most of them are photosensitive, therefore they lose their effectiveness under the sun’s rays.

Once the application is complete, eliminate the internal pressure of the sprayer by operating the valve: you will thus extend its useful life.

We hope these tips will help you and clarify some of the doubts about how to cure plant diseases!
