biotic vs. abiotic
A factor caused by a living organism, such as a fungus or insect, is described by this term.
What is biotic?
These reproductive units can travel to a new host or growing surface.
What are spores?
Removing diseased plants and plant debris helps reduce disease sources through this practice.
What is sanitation?
Tumor-like swollen galls on stems and roots at the crown are caused by this soilborne bacterium.
What is crown gall?
A factor caused by a nonliving condition, such as low light or high temperature, is described by this term.
What is abiotic?
This process begins when a spore starts to grow under favorable conditions.
What is germination?
Regularly checking plants to spot symptoms and problems early is called this.
What is scouting?
Water-soaked leaf spots with edges limited by the veins become angular; later, they dry and tear out.
What is angular leaf spot?
A nutrient deficiency in growing media belongs to this category of plant disorder
What is abiotic?
After colonizing plant tissue, a fungus forms structures for this stage, which produce new spores that can later disperse.
What is reproduction?
Keeping newly delivered plants separate while checking for pests and disease is part of this practice.
What is quarantine?
Water-soaked leaf spots turn brown, often with a yellow halo, and spread through splashing water and handling wet plants.
What is bacterial blight?
A virus causing mottled leaves is an example of this kind of factor.
What is biotic?
These threadlike structures form as a fungus grows.
What are hyphae?
Moving air through the growing area helps reduce stagnant, moist conditions by improving this.
What is air circulation?
This bacterial disease turns the stem base black and soft or rotten, causing wilting and plant collapse, often in wet conditions.
What is blackleg?
Similar leaf symptoms across many plants after an irrigation failure may point to this type of cause rather than a spreading pathogen.
What is an abiotic factor?
This is the network of fungal threads formed by hyphae
What is mycelium?
This organized approach combines monitoring and appropriate management methods to protect plant health.
What is integrated pest management (IPM)?
In apple and pear relatives, this disease caused by Erwinia amylovora makes shoots wilt into a shepherd's crook, while blossoms and leaves look scorched as if burned.
What is fireblight?
