A vector is an organism that can carry pathogen(= disease causing organism) from infected plant to a health plant. Generally, a vector is an insect, a nematode, a fungi, or insect like organisms e.g. spider mites. To qualify as vector, the organism must have the ability to acquire the pathogen, must be able to retain the pathogen for some length of time and lastly it must be able to inject it into a suitable/susceptible plant. The relationships between the vector and pathogen can be described as simple if the pathogen does not circulate or replicate in the vector or complex if the pathogen replicates or circulate in the vector. In the latter case, the vector also acts as the host of the pathogen.
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
Resultant vector or effective vector
Vector spaces can be formed of vector subspaces.
decomposition of a vector into its components is called resolution of vector
History of plant pathology in the Philippines?
Australasian Plant Pathology was created in 1972.
British Society for Plant Pathology was created in 1981.
Australasian Plant Pathology Society was created in 1969.
"diseases of cultivated crops,their causes and their control"
Three major areas of plant science are plant physiology, plant genetics and breeding, and plant pathology. Plant physiology studies how plants function and respond to their environment, while plant genetics and breeding focus on improving plant traits through selective breeding. Plant pathology deals with the study of plant diseases and their management.

who is the father of pathology??
because the can kill plants by sucking the sap and vector plant viruses and diseases

Gross pathology refers to what can be seen with the naked eye, and microscopic pathology uses a microscope.
