Tomato is one of the most common crops in any garden, especially in urban ones. The tomato is a plant whose care is available to everyone and its fruits can be enjoyed in so many recipes and in so many ways that it is difficult to resist planting a few to benefit from their harvest.

There are various pests of tomato plants that affect the entire plant, from the stem and leaves to the fruits themselves. Here we explain the most common:
- The Red spider: caused by Tetranychus urticae, It is one of the main pests of tomato plants. These small reddish or yellowish arachnids, as their name suggests, are very small and attack the plant by sucking its cell juices to feed. The result is that the affected areas of the plant turn yellowish and eventually become necrotic. When there are many, they form easy-to-identify webs that they use to travel between plants.
- the white fly: caused by Trialeurodes vaporariorum and Bemisia tabaci, the whitefly lays its eggs on the underside of the young leaves of the plant, so that later the larvae feed on them. It directly harms the plant, but indirectly what it does is favor the proliferation of bold. On the other hand, we leave you this article on the Whitefly: how to eliminate it.
- aphid on tomato plants: caused by Aphis gossypii and Myzus persicae, appears in spring and autumn. The way in which aphids act on tomato plants is by forming colonies and distributing small foci. In addition, it is very typical in a wide variety of plants.
- thrips: known under the scientific name of Frankliniella occidentalis, They lay their eggs in the fruits, leaves and flowers inside the plant tissue. It is in this place where they lay large eggs and where the adult populations are found.
- leaf miners: we can talk about four different types of leafminers, where we find Liriomyza trifolii, Liriomyza bryoniae, Liriomyza strigata and Liriomyza huidobrensis. All of them lay their eggs inside the young leaves, from where the larva digs to feed. It is here that we witness the typical galleries.

- gray rot: it is caused by the fungus Botrytis cinerea that causes brown or grayish spots to appear on the leaves, stems and flowers, which also causes a wet and soft rot in the fruits.
- anthracnose: caused by fungus destructive speech, It appears during the ripening of the fruits, in the form of spots with the appearance of rot, which increase in size with time, making the tomatoes useless for consumption.

- Mildew: under the scientific name of Phytophthora infestans, another fungus that affects the tomato plant in all its development phases and causes wet-looking spots to appear on all its leaves and stems.
- Alternariosis: the last of the tomato diseases is caused by alternaria solani, that generates circular spots with concentric rings, which end up causing affected areas of a dark and elongated color and darkened and sunken areas in the fruits.
