As a continuation of the previous article on pests and diseases, we bring you the 2nd and last article in this series. If you missed the previous article you can read in Types of Phytosanitary Part 1.

Other types of phytosanitary products are:

Herbicides

They are compounds that prevent the development of weeds, which compete with plants for nutrients, water and sunlight, and are carriers of pests and diseases. They are applied by fumigation, on the leaves or the soil, in early autumn and spring. One of the most widely used herbicides is glyphosate, which kills all types of annual and perennial weeds and is lethal to grasses. Sulphosate, which penetrates to the roots, is also effective. However, they must be applied with care so as not to affect good plants.

Ecological plant protection

Both industry and the old wisdom of gardeners have led to more natural and ecological plant protection in recent years. These are just a few examples:

Paraffin oil. It is applied in winter, as an insecticide and acaricide on plants that have been attacked the previous season. By means of an atomizer the plant is soaked forming a layer on the eggs and insects, which prevents them from breathing.

Vegetable oils of olive, sunflower, mint or pine It is effective against mealybugs if their number is not excessive. It is applied with a brush on the leaves.

Sulfur

It prevents the appearance of oidium, although it is also used against mites. It is sprinkled on the plant.

Pheromones

Pest control systems use them in insect traps: the males are attracted by the effect of the sexual hormones of the females of the species.

Rotenone

It is extracted from the roots of some tropical leguminous plants. It is an insecticide and acaricide and acts by contact and ingestion. It must be applied in low light hours.
