DESCRIPCIÓN

Descripción del patógeno

Fusarium wilt is a fungal disease caused by different species of the genus Fusarium, which affects a wide range of plants, including cucurbits. This pathogen can survive in soil for long periods of time and can enter plants through wounds in roots or stems, or by germination of spores under favorable conditions.

Descripción de la enfermedad

In cucurbits, fusariosis causes symptoms such as sudden wilting of the plant, yellowing and necrosis of the leaves, as well as the decomposition of the internal tissues of the stems and fruits. These symptoms can appear gradually and progress rapidly, eventually leading to the death of the plant if the disease is not controlled in time.

TEMPERATURA Y HUMEDAD

70% - 90%

VÍAS DE TRANSMISIÓN

Contaminated soil, infected seeds, crop remains, contaminated irrigation water, agricultural tools, transportation of infected plants.

To prevent fusariosis in cucurbit crops, it is important to practice crop rotation and avoid monoculture, as this can reduce the accumulation of pathogens in the soil. In addition, it is recommended to maintain a good soil structure and adequate drainage to avoid waterlogging, which favors the development of Fusarium. It is also useful to use resistant varieties when possible and avoid planting in soil contaminated with the pathogen.
