1. Leggy Stems. While more common when starting seeds, stretched out, leggy stems can also be an issue with houseplants. The stems grow longer, and the space between leaf nodes elongates as the ...
The fungus can survive on infected tissues, in the soil, and on living plants. It affects young seedlings, mature plants, and fruit in the field or in storage. White mold can spread quickly in the field from plant to plant. It can also spread in a storage facility throughout the harvested crop.

Sowing seeds in a sterilized growing medium can be effective, although fungal spores may still be introduced to the medium, either on the seeds themselves or after sowing (in water or on the wind).
Leggy tomato plants, or those that have grown tall and spindly, can be avoided if you take certain steps while growing them indoors. Leggy tomato plants, or those that have grown tall and spindly ...
The leaves of plants experiencing root rot often yellow and die, and if allowed to continue, the condition can be fatal to the plant.

Using a dense potting media such as one dug up from outdoors can also cause root rot.
When a suitable medium is located, the hairs surrounding the spore will lock onto the substrate so that the sexual reproduction phase can start. It is also during this stage of polyplanetism that the Saprolegnia are capable of causing infection; the most pathogenic species have tiny hooks at the end of their hairs to enhance their infectious ...
Unidentified water mold on dead larval mayfly. A culture of Achlya sp. (Saprolegniales) isolated from a stream. Sea trout suffering from UDN with secondary Saprolegnia infections. Many oomycetes species are economically important, aggressive algae and plant pathogens. [13] [14] Some species can cause disease in fish, and at least one is a ...
