Fusarium oxysporum f.sp. lycopersici
Fusarium oxysporum f.sp. lycopersici
Fusarium oxysporum f.sp. lycopersici is a plant pathogenic fungus that specifically targets tomato plants (Solanum lycopersicum). It is a formae specialis of the species Fusarium oxysporum, which is known to infect a wide range of plant species.
Description[edit | edit source]
Fusarium oxysporum f.sp. lycopersici infects tomato plants through the roots and vascular system, causing a disease known as Fusarium wilt. The fungus colonizes the xylem vessels, leading to wilting, yellowing of leaves, and ultimately plant death. It is a soil-borne pathogen that can persist in the soil for several years.
Management[edit | edit source]
Management of Fusarium wilt caused by Fusarium oxysporum f.sp. lycopersici includes the use of resistant tomato varieties, crop rotation, and soil sterilization. Fungicides may also be used, although their effectiveness can vary.
Impact[edit | edit source]
Fusarium wilt caused by Fusarium oxysporum f.sp. lycopersici can result in significant economic losses for tomato growers. The disease is widespread in tomato-growing regions around the world and can be challenging to control once established.
Research[edit | edit source]
Research on Fusarium oxysporum f.sp. lycopersici focuses on understanding the genetic basis of pathogenicity, developing molecular markers for resistance breeding, and exploring alternative methods for disease management.
