Over use of chemical pesticides and herbicides can lead to resistant bugs or weeds. It is quite a common issue now in conventional horticulture and agriculture. Alternating the chemicals used will help to stop a pest building up that resistance, using mixed cropping rather than a monoculture helps with pest control and the use of cover crops will help keep weeds at bay as well.
