tomato yellows
Definition
Noun: - A specific plant disease affecting tomato plants, characterized by yellowing of the foliage, stunted growth, and reduced fruit yield. It is typically caused by viral or phytoplasma infections.
Usage
- The term is used specifically in agricultural, botanical, and gardening contexts to diagnose and discuss the health of tomato crops.
- It functions as a singular noun, often used with a singular verb (e.g., "Tomato yellows is spreading"), but can refer to the general condition affecting multiple plants.
Examples
- The entire crop was lost due to a severe case of tomato yellows.
- Tomato yellows is often spread by leafhopper insects.
- A gardener must identify tomato yellows early to prevent it from affecting other plants.
Advanced Usage
- The term can be used in a more general sense to describe similar yellowing symptoms in other plants, though this is less common and should be clarified by context (e.g., "a condition like tomato yellows").
- In technical literature, it may be specified further (e.g., "beet leafhopper-transmitted tomato yellows").
Variants and Related Words
- Yellow leaf curl: A specific viral disease causing similar yellowing and curling in tomato leaves.
- Aster yellows: A related phytoplasma disease affecting a wide range of plants, including tomatoes, causing similar yellowing symptoms.
Synonyms
- Tomato yellow leaf curl (for a specific viral form)
- Tomato disease (general)

Notes on Meaning
- The primary meaning is a disease causing yellowing. It is not used to describe the color of a healthy yellow tomato fruit.
- It is a compound noun where "yellows" is a plural form denoting the disease syndrome, not multiple yellow objects.
Noun
-
a disease of tomato plants
