HATE IN THE TOMATO
Powdery mildew is a fungus that is generated in good conditions of humidity and temperature. He is whitish color from the top of the leaf. Over time, it yellows and eventually dries the leaf. As a home remedy for this disease of tomato plants, organic, we have wettable or powdered sulfur, apply homemade fungicides that we can make ourselves such as fungicide milk, horsetail, nasturtium infusion or purine d ‘nettle. Also, if you have an urban garden and you can put the plants in the sun, the fungus dies.

ROT IN TOMATO
Powdery mildew and botrytis are fungi that damage the plant.
The botrytis turns the affected area brown while the other produces a cottony white area. Both are combated with copper sulfate, potassium soap (you can get it here) and garlic extract, or apply homemade fungicides that we can make ourselves like milk fungicide, horsetail, nasturtium infusion or nettle purine.

This is another fungus that produces a black spot both on the leaves, as well as on the stem and the tomato. It is controlled with manure ponytail, sage, nettle and tansy. Copper sulphate can also be applied.
VIRUSES AND OTHER DISEASES THAT AFFECT TOMATOES
VIRUSES IN TOMATO
There are multiple viruses that affect tomatoes and apart from preventive control, does not exist a way to fight them. If general symptoms such as dwarfism and yellow color are observed on almost the entire tomato plant, it is advisable to cover it with a bag, remove it and dispose of it to prevent it from becoming spread to the rest of the plants.
BIPPER ROT
I have included this disease here because it is generalized by a deficiency in calcium in the plant or the lack of assimilation of this mineral. We can apply an infusion of eggshells or before starting the cultivation add eggshells. The fruit appears black underneath, with very characteristic spots as seen in this photo of the disease.
CUTTING TOMATOES
It occurs during a sudden change or a sudden drop in temperature and/or more commonly due to a imbalance in irrigation, lacking water for several days.
NUTRIENT DEFICIENCY
A deficiency in basic nutrients can manifest itself in the leaves of our plants, in fact this is a fundamental area to monitor. Of course, not because only one or two leaves have it because it is not significant, it is better to observe and see how the others behave. For this I leave you 10 homemade fertilizers that we can do at home. Additionally, we can use humus tea to strengthen the plant and the soil.
I hope you have learned about tomato diseases, both from the explanation and the photos, as well as the most common tomato pests, and how to treat or avoid these diseases that commonly affect tomato plants. tomatoes.
