Endogenous inhibitor
An organism can produce a substance that at a low concentration, inhibits the growth of itself or another organism or some physiological process associated with growth. This is known as a growth inhibitor. In higher plants, growth inhibitors like abscisic acid (ABA) exhibit a distinct characteristic their effects can be countered by specific growth promoters,…

Endemic disease
A malady that has taken root in a particular geographic region, typically encompassing a nation or a portion thereof, and has become firmly established in a state of moderate to severe severity. Within the realm of infectious diseases, there exists a category of ailments that frequently manifest within a specific geographical locale. These diseases demonstrate…

Effective inoculum dose:
The amount of inoculum which is available for penetration of the plant tissues. This may be equivalent to the inoculum concentration used or only a proportion of it, e.g. in leaf scar inoculations the amount of inoculum which enters is dependent upon vascular tension in the plant and rate of evaporation etc.

Edaphosphere
The soil that lies beyond the rhizosphere, where plant roots no longer hold sway, is a subject of great intrigue to soil scientists and researchers. This region is known as the bulk soil, where a diverse array of microorganisms, minerals, and organic matter interact with each other in complex and fascinating ways. The perplexing nature…

Dwarfing
A reduction in the total dimensions of the plant, while keeping the relative sizes of its individual components unchanged.

Drop spectrum
The dispersal, as quantified by either the number or volume of droplets, of an atomized mist is distributed among defined ranges of droplet sizes.
-
Disinfestant
An agent that kills organisms present on the surface of plants or plant parts, or in the immediate environment, e.g. in soil.

Disease potential
J. Grainger introduced a phrase to describe the biological state of a plant that influences its susceptibility to illness. The phrase is represented by the ratio of Cp/Rs, where Cp stands for the overall carbohydrate content of the entire plant, and Rs is the residual dry weight of the plant’s stem. This concept was initially…

Disease gradient
The alteration in disease prevalence in relation to the proximity from the infectious origin point.
-
Disease escape
the failure of a host to become diseased because of separation, in space or time, of susceptible host tissues and the infective units of the pathogen, e.g. an air-borne pathogen may not arrive in contact with the host until after the susceptible period has passed; climatic conditions may not permit the germination of a pathogen…
