INTERNATIONAL HERBICIDE-RESISTANT WEED DATABASE
LIFECYCLE DURATION OF HERBICIDE RESISTANT WEEDS VS WEED SPECIES IN GENERAL

The following two pie charts show the lifecycle duration for all of the herbicide-resistant weeds in the database in comparison to the lifecycle duration of 3,272 known weeds. It is clear that herbicide-resistant weeds are more likely to be annuals or biennials than perennials in comparison to weeds in general.
