The use of some pesticides may contribute to the development of resistance among the target pests. Extensive herbicide use resulted in genetic modifications in some weeds with resistance to pesticide compounds. The use of the same herbicides in some areas for many years led to the development of immunity to the herbicides among targeted plant species. Resistance makes weed control considerably difficult.
