Plant Pathologist

Gardener working with plants

A plant pathologist is someone who's interested in understanding the organisms and agents that cause plant diseases and how diseases affect plant health. There are a great range of plant pathology careers. Most plant pathologists work in university departments, commercial companies or do government funded research.

Some of the things a plant pathologist does:

  • Diagnose and deal authoritatively with enquiries about plant disease
  • Undertake research, publish results and communicate the results to gardeners
  • Assist in the preparation of proposals for research projects
  • Work with relevant organisations and attend conferences to promote horticultural plant pathology
  • Help prepare lectures, examination materials and demonstrations on plant diseases.

Pathologists are mainly employed as researchers or consultants who work in a variety of fields aimed at tackling crop or garden pests and the insects and diseases that spread plant, human and animal diseases. Pathologists are also concerned with the conservation of our native flora & fauna and their habitats.

Most pathologists are employed by various public organisations, such as the research institutes, museums, universities and national and local government departments concerned with agriculture, horticulture, health, conservation and environmental protection.

In the private sector they are employed by agricultural estates, pest control contractors and companies that develop and manufacture biological and chemical insecticides, and by environmental consultants, County Wildlife Trusts and other environmental charities.

Working Conditions 

Working hours will vary according to the exact nature of the job.

Plant Pathologists working in research and higher education usually work a standard full time week, Monday to Friday. Additional hours may be required at busy times. Those working in conservation may be required to host open days for the public or work with volunteers at weekends and bank holidays. They may also have to go to evening meetings.

Plant Pathologists can work all over the world and may have to cope with difficult climates. Fieldwork can be physically demanding.

A driving licence is often required to travel between different places of work.
