WHO CAUSES IT?
Plant viruses are pathogens that directly affect plant development and are incurable once a plant is infected. Unlike fungi or bacteria, viruses cannot be eliminated with treatments, so the problem is often more serious. They are mainly transmitted through insects (such as aphids, whiteflies, or thrips), contaminated tools, contact between plants, or even seeds in some cases.
When a virus enters a plant, it disrupts its internal functions, especially tissue formation and chlorophyll production. This is why symptoms such as spots, deformities, or changes in leaf color appear. Often mistaken for nutrient deficiencies or watering problems, viruses usually cause more irregular and persistent symptoms. The key is to detect them early and prevent their spread.

SYMPTOMS
Viruses can cause a wide variety of symptoms, but they usually affect leaves and new shoots.
Typical symptoms:
• Irregular light and dark green spots (mosaic pattern).
• Deformed, wrinkled, or smaller than normal leaves.
• Unusual yellowing that doesn't follow a clear pattern.
• Weak growth or stunted plant growth.
• Deformed or poorly developed flowers or fruit.
• General loss of vigor.
Unlike other problems, the symptoms are usually irregular and do not improve over time.
Stages of development:
• Initial: slight spots or color changes on young leaves.
Intermediate stage: deformities and irregular growth.
Advanced stage: general weakening and low yield.
Final stage: severely affected, unproductive plant or stunted growth.
DEVELOPMENT CONDITIONS
Temperature:
18ºC - 28ºC
Humidity:
60% - 80%
HOW IS IT SPREAD?
They are primarily transmitted through insect vectors such as aphids, whiteflies, or thrips, which pass the virus from one plant to another as they feed. They can also be spread by contaminated tools, contact between plants, infected seeds, or even by human handling.
