Root Rot

Root rots are soil-based pathogens that infect plants through their root systems.

They fall into basically three types;

Pythium root rot:

This type of rot invades the root tips, causing black rot to develop.

Symptoms:

It blackens the bulbs, drains the water and hardens the root. Plants stop growing and eventually die.

Control:

Avoid overwatering, grow in well-drained soil and practice good garden hygene with prompt removal of affected plants.


Phytophthora root and crown rot:

This type attacks the root tips and stems, forming brown rot.

Symptoms:

These act in a similar manner to phythium; however, these diseases also manifest in the stems.

Control:

Avoid overwatering, grow in well-drained soil and practice good garden hygene with prompt removal of affected plants.


Verticillium wilt:

This type clogs the water-gathering tissues.

Symptoms:

Limp appearance and accelerated wilting.

Control:

Avoid planting in previously affected areas and fumigate the soil.
