Tomato Yellow Leaf Curl
Tomato yellow leaf curl is a disease of tomatoes caused by the whitefly-transmitted virus, Tomato Yellow Leaf Curl Virus (TYLCV). This disease was first observed in Louisiana in 2000 and since then has occurred sporadically in both field- and greenhouse-grown tomatoes. After a plant becomes infected, new growth is severely stunted and fruit production ceases. Disease management relies on use of disease-free transplants, planting resistant varieties and controlling whiteflies. |
Tomato Southern Blight
Southern blight (or southern wilt) is a disease of hundreds of plant species, including tomatoes. It is favored by moist conditions and high temperatures. The fungus can survive for years in soil and plant debris. |

Tomato Fusarium Wilt
Fusarium wilt of tomato is caused by the soil-borne fungus Fusarium oxysporum f. sp. lycopersici. This pathogen infects roots directly or enters through wounds and rapidly colonizes the xylem of the infected plant. This disease usually occurs during periods of hot weather from blossoming to fruit maturation. Because this pathogen can persist in infested soils for many years, avoiding areas with a history of Fusarium wilt and planting resistant varieties are your best management options. |
Tomato Bacterial Speck
Bacterial speck is favored by cool temperatures and high-moisture conditions. Severe fruit spotting can decrease yield potential by reducing its marketability. |
