Tomato yellows causes the leaves to turn pale and curl.

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)
• Yellows (in a broader plant pathology context)

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.
