Release Date: 
18/12/2013
This factsheet outlines how the repeated use of insecticides, fungicides and herbicides if not properly managed, can result in the development of resistant pest, pathogen and weed populations. It lists the known cases of resistance that may potentially cause problems in the control of a range of pests, diseases and weeds that commonly occur on horticultural crops in the UK and advises how to prevent resistant strains developing.
