Description of aspermia in tomatoes
Aspermia is a viral disease that mainly affects adult tomato bushes. It is also known as bushiness of the top of tomatoes. It manifests itself in a slowdown in the development of tomatoes and a decrease in their yield. When affected, not all plantings suffer, but only some bushes.
Reasons for appearance
Most often, the tomato aspermia virus enters the area together with vectors. They are cicadas, whiteflies and aphids. In addition, the disease can be transmitted from an infected bush to a healthy plant. However, it is not always possible to understand that it is affected.
The carriers can be grasses that enter the area as animal feed or mulch. In addition, the causative agent of the disease may be in soil that was brought from another place.
Almost all strains lack resistance to adverse weather conditions. This explains that the tomato disease aspermia occurs mainly in the southern regions. In areas with cold climates, this disease is not common.
Failure to follow recommendations for caring for tomatoes significantly increases the chance of the disease appearing and developing. It is worth monitoring the amount of watering. Excessive moisture in the soil creates favorable conditions for the development of aspermia.

If you do not pay attention to the symptoms in a timely manner and do not take appropriate treatment measures, the disease will spread to all plants in the immediate vicinity.
Symptoms of infection differ depending on what stage of growth the bushes were in at the time of infection. You can tell that the seedlings are sick by the fact that fruits do not form after flowering. If the damage occurs at the time of fruit formation, then the main symptom is a small harvest. In this case, the tomatoes will be deformed in shape and there will be no seeds inside.
In addition, tomatoes affected by aspermia have other signs:
- weakened and pale stem;

If measures are not taken in time, there may be no harvest or the bush will die.
