Insecticides are products that can save a plant that has a pestbut they may also not be useful at all. It is important to keep in mind that there are a wide variety of insects that attack crops, and insecticides are often only useful against a few.
In addition, we cannot forget about the safety measures that you must take, especially if we buy a chemical insecticide for plants, such as wearing rubber gloves and not applying them if it is windy. For all this, We will explain how to choose one.
Top 1. The best insecticide for plants
- Effective against a wide variety of pests: aphids, ants, mealybugs, red spider mite, thrips, whitefly.
- It is natural and environmentally friendly.
- Leaves no residue.
- It is not toxic.
- It also serves as a fertilizer as it contains the three macronutrients (nitrogen, phosphorus, and potassium), as well as other equally important ones such as calcium, magnesium, iron, manganese, copper, and zinc.
- Although it is not toxic, it is a dehydrating product. That is why if it is kept on the skin for a while we can feel itching and irritation. But these symptoms disappear as soon as we wash with soap and water.
- The price may seem high, but if you have few plants or they are small, it is worth it, since you only have to sprinkle them a little on top (as if you were adding salt to a salad).

Although these traps cannot be considered insecticides, we wanted to include them because they are so effective that they can help us reduce the use of chemical pesticides. The yellow ones are ideal for controlling aphids, whiteflies, moths; and the blue ones for thrips. There are two sizes: 20 x 15 centimeters and 25 x 15 centimeters, but you can still cut them if they are large. Put them in the seedbeds, hanging from the branches or trellises. The insect will be attracted to them and, once it touches it, it will no longer be able to detach itself.
Buying guide for an insecticide for plants
How is an insecticide chosen? It is not always easy, but we hope that these tips will help you in your choice:
Chemical or ecological?
Although it is always preferable to opt for ecological insecticides, we cannot forget that their effectiveness when the plague is already very advanced is often not what is desired. I have been growing plants since 2006, and until now the only organic product that has really served me as a cure is diatomaceous earthwhich eliminates even fleas. Therefore, when the plant is very bad, it is almost better to clean it with water -without lime- to remove the pest, and treat it with chemical insecticide.
Spray, or to dilute?
In the selection we have focused on spray insecticides, because they are the ones that have a simpler mode of application by simply having to spray the plants. But there are some that have to be diluted first in water. This does not mean that some are better than others, but If we do not have much experience yet, we recommend choosing spray insecticidesready for use.
Triple action, double action or only insecticide?
And triple action It is a product that is used to combat insects, mites and fungi, so it is very useful when a plant has, for example, aphids, red spider mite and the black fungus; the double action it can be an insecticide and acaricide, that is, it can be used to combat insects and mites such as the red spider, or an insecticide and fungicide (insects and fungi); and the insecticides They are those that only serve to eliminate insects. Depending on what problem or problems our crops have, we can use one or the other.
How to use an insecticide on plants?
The first thing to do is read the container label. Forever. Although it is an ecological insecticide, it is important to know what pests it is effective against and how to use it, if not, problems could arise or it may not help us to solve the problem of our plant.
Then we should put on rubber glovesespecially if we are going to apply chemical insecticides, since if it comes into contact with the skin we could feel itching or irritation at least. Y only then can we apply the product.
It must be done as indicated on the label, avoiding its application on days when there is wind. What’s more, if the plant to be treated is outdoors, it must be applied in the late afternoonwhen the Sun no longer gives it, otherwise it would suffer burns.
How to make a homemade insecticide for plants?
You can make homemade insecticides with many things you have around the house. For example:
- Water and neutral soap: in a liter of water you have to add a small tablespoon (of coffee) of neutral soap, and then mix well. Afterwards, use this mixture to clean the affected plant.
- Garlic: Take a head of garlic and chop it well, carefully. Then, put the pieces in a liter of alcohol and put them in the fridge for 1 hour. Then you just have to add 2 liters of water, stir and finally filter. With the resulting mixture you can fight aphids, mealybugs and whitefly.
- Lemon: If you have a plant with a trunk that has a lot of ants, it is a good idea to cut a lemon in half and rub it against the trunk.
