How to combat pests of tomato crop

Tomato cultivation can be affected by many pests, diseases and viruses. In this entry I will compile the most important ones.

Plagues:

-Aphid
The aphid is a pest that must be controlled as soon as possible because it spreads very quickly throughout the plant consuming its sap. It hides in the lower part of the leaves, in the stems and shoots young. As we had already talked about the aphid, I leave the solution by clicking here.

-White fly
The whitefly transmits diseases to our tomato plants and also sucks the sap. It is better to prevent it by trapping. The solution by clicking here.

-Trips
Thrips also cause indirect damage as it transmits tomato tanning virus. The best way to combat it is prevention. The method would be the same as that of the white fly but with posters and blue bottles.

-Butterfly caterpillars
There are multiple species of butterflies that feed on the plant, among them the Tuta absoluta, Spodoptera sp, Heliothis armigera. They all have the same solution. Click here.

-Minelayer
The only ecological control of this pest is to detect the galleries they make on the leaves, rip them off and burn them.

-Red spider
The red spider can quickly weaken a tomatero, this plague we have talked about before, so I leave this link.

Diseases:

-Oidio
It is a fungus that is generated under the right conditions of humidity and temperature. It is whitish by the bundle of the leaf. Over time it turns yellow and finally causes the blade to dry. As an ecological remedy is wet or sulfur powder. Also if you have an urban garden and you can put the plants in the sun, the fungus dies.

-Mildew
It is a fungus that like the oidio affects the leaves of the plants. On the leaf are spots of light or dark green, becoming necrotic with time. Copper sulphate is generally used as an ecological treatment.

-Rust
It is a fungus with orange coloration on the underside of the leaf and yellowish on the bundle. Both this and the above fungi can be treated with a decoction of horsetail. It can also be treated with Copper Sulphate.

-Rot
Both the white rot and botrytis are a fungus that causes lesions in the plant.

Botrytis causes the affected area to turn brown while the other produces a cottony, white area. Both are combatted with Copper Sulphate, Potassium Soap and Garlic Extract. Prevention is very important, avoid cuts in plants that can become infected, do not have plants close together and eliminate any affected area.

-Scab
It is another fungus that produces a black stain both on the leaves, on the stem and the tomato. It is controlled with purine of horsetail, sage, nettle and tansy. Copper sulphate can also be applied.

Viruses and other alterations:

-Virus
There are multiple viruses that affect tomatoes and unless preventative control there is no way to combat them. If general symptoms such as dwarfism and yellow color are observed in almost all the tomatero, it is advisable to cover it with a bag, to start it and to eliminate it to avoid that it is propagated by the rest of the plants.

-Apical rot
This disease I have included here because it is generated by a deficiency of calcium in the plant. The fruit appears black from below.

-Streaking of tomatoes
It occurs when temperatures drop rapidly or there is an imbalance in irrigation.
