tomato disease
PlantVillage None Given
Tomato plant aborting the flower, small fruits become dried but not all plants have the symptom. Is possible some virus? Help me please, is this possible the same virus occurs on one plant but not all.
UPDATE
Sorry, I don't have the leave symptoms, the farmer comment the color on leaves, but I send other picture on fruit.

This could be possibly a virus disease on your tomato. There are several virus that infect tomato like
Tobacco mosaic virus single streak and double virus streak virus
Tobacco etch virus (TEV) and potato virus Y (PVY)
Potato leafroll virus (PLRV)
Tomato spotted wilt virus (TSWV)
Cucumber mosaic virus (CMV) etc.,
This virus causes varied symptoms like mosaic, mottling or puckering or curling of leaves. The infected stem and petiole may show streaking. Fruits may become rough, deformed or spotted. Dropping of flower and fruits. Stunting of infected plants.
Generally the viruses are transmitted by seeds, mechanical, insects (aphids, thrips, whiteflies), weed hosts and previous infected plant debris.
Best approaches to follow: Roughing- remove the infected plants and burn them. Keep the field free from weeds and crop debris. Use healthy certified seeds. Control the insect vectors.

Symptoms due to Double virus streak is caused by a strain of tomato mosaic tobamovirus and potato virus X potexvirus
