Biological control
The employment of natural adversaries to regulate the prevalence of vermin (or pathogens) originated as a biological tactic. Nonetheless, it would be sensible to subsume within this classification any technique that relies entirely on biological associations to suppress pests or illnesses, such as host resilience and crop rotation.

Beaumont period
A Beaumont period refers to a span of two consecutive days where the temperature remains above 10°C while the relative humidity levels exceed 75%. Such conditions are regarded as favorable for the spread of Phytophthora infestans, a pathogen that infects potato leaves. It is anticipated that the occurrence of potato blight will manifest itself about…

Axeny
The concept of inhospitality refers to the passive, rather than active, resistance of a plant to a pathogen. This phenomenon is characterized by the plant’s ability to create a hostile environment for the pathogen, which prevents its growth and proliferation. The term “passive” resistance denotes that the plant is not actively attacking the pathogen, but…

Antisporulant
A substance which inhibits or reduces the formation of fungal spores without eradicating the fungal vegetative growth.
-
Anti-fungal substance
The composition, whether identified or not in terms of its chemical structure, has the ability to diminish the development of fungal spores in aqueous solutions or the rate of growth of fungal hyphae at an EC 50 value of 100 μg/ml or less. Typically, complete suppression of fungal growth is achieved at a concentration below…

Alternate host
One could identify either one of two hosts that can harbor a heteroecious pathogen such as rust, or a heteroecious pest such as an aphid. In the event that several or numerous plant species serve as hosts for a particular pathogen, they may be referred to as alternative hosts.
-
Aggressiveness
J. E. van der Plank proposed that strains of a pathogen that exhibit varying levels of harmful effects but do not display distinct interactions with different host varieties should be classified as differing in aggressiveness, while strains that do display varying interactions with host varieties should be categorized as differing in virulence.

Acquisition threshold period
The smallest increment of time that a vector must spend on a source of virus to acquire an infectious amount of the viral particles.
-
Acquisition feeding time
In the realm of transmission tests, there exists a period of time during which a vector consumes a source of viral material. It is important to note that this period of time is not interchangeable with the acquisition access time.
-
Acquisition feeding
In transmission tests, the act of a vector feeding on a virus source is a critical component to observe. This process involves the ingestion of viral particles by the vector and subsequent transmission to a host. The complexity of this mechanism lies in the intricate relationship between the vector and the virus, as well as…
