Damage caused by drying of branches and shoots in decorative garden and/or indoor plants

WHO CAUSES IT?

The pathogens Phoma sp., Phytophthora sp., Monilia sp. and Verticillium sp. They are fungi that affect a variety of plants. Phoma sp. It spreads primarily through spores that are released during periods of humidity and carried by wind or rain, infecting plants through wounds or stomata. Phytophthora sp. It is a soil pathogen that produces motile spores that spread in water, infecting the roots and vascular system of plants. Monilia sp. It develops in conditions of high humidity, infecting flowers and fruits, leading to the formation of spores that spread easily. Verticillium sp. It invades plants through the roots and moves into the vascular system, where it produces spores that can remain in the soil for several years, infecting new plants grown in the same location. These pathogens have the ability to survive in infected plant remains and in the soil, allowing them to persist from one season to the next.

SYMPTOMS

The branch and shoot drying disease caused by these pathogens in plants manifests itself through a series of symptoms that seriously affect the health and productivity of the plants.

- Wilting of leaves and shoots.
- Regressive death of branches.
- Appearance of dark Taches on stems and branches.
- Discoloration and necrosis in the vascular tissue.
- Premature fall of leaves.
- Drying of new shoots.
- Reduction of plant vigor and growth.
- Presence of gummy exudates in some affected species.

Biological treatments

Recommendations

- Carry out regular inspection of plants for early signs of infection.
- Remove and destroy infected parts of plants to prevent the spread of the pathogen.
- Use plant varieties resistant to these pathogens.
- Avoid excess watering and improve soil drainage to reduce excessive humidity.
- Apply preventive fungicides according to the manufacturer's recommendations.
- Maintain an adequate crop rotation to prevent the accumulation of pathogens in the soil.
- Implement agricultural hygiene practices, such as disinfection of tools and removal of infected crop remains.
- Promote adequate ventilation in greenhouse crops to reduce relative humidity.
- Use biological treatments such as antagonistic fungi to reduce the incidence of these pathogens.
