Pesticides and herbicides

Pesticides are commonly used to control invasives. Herbicides used against invasive plants include fungal herbicides. Although the effective population size of an introduced population is bottlenecked, some genetic variation has been known to provide invasive plants with resistance against these fungal bioherbicides. Invasive populations of Bromus tectorum exist with resistance to Ustilago bullata used as a biocontrol, and a similar problem has been reported in Microstegium vimineum subject to Bipolaris microstegii and B. drechsleri. This is not solely a character of invasive plant genetics but is normal for wild plants such as the weed Linum marginale and its fungal pathogen Melampsora lini. Crops have another disadvantage over any uncontrolled plant – wild native or invasive – namely their greater uptake of nutrients, as they are deliberately bred to increase nutrient intake to enable increased product output.
