 Description, Cockleburs -- Vet Med Library, UIUC
Cockleburs occur throughout Illinois and the rest of the U.S. as stray plants in waste places, cornfields, pastures, and along roadsides, fencerows, stream banks, the beds of dry ponds, and previously flooded land along streams and rivers.
Pastures and meadows may be heavily infested, especially with the seedling stage as the result of the burs having been washed in from adjoining fields.
Pigs rooting and grazing in cocklebur infested places are the most often poisoned domestic species, with those weighing between 20-50 pounds being the most susceptible.

 Cocklebur - Wikipedia, the free encyclopedia
The Cockleburs (Xanthium) are a genus of flowering plants in the family Asteraceae, native to the Americas and eastern Asia.
Unlike many other members of the family Asteraceae, whose seeds are airborne with a plume of silky hairs resembling miniature parachutes, cocklebur seeds are produced in a hard, spiny, globose or oval double-chambered, single-seeded bur 8-20 mm long.
Cockleburs are short-day plants, meaning they only initiate flowering when the days are getting shorter in the late summer and fall, typically from July to October in the northern hemisphere.

 G4907 Herbicide Resistance in Weeds, MU Extension
It is noteworthy that this cocklebur was completely resistant to Classic, even though it had never been sprayed in the field, and was completely resistant to Broadstrike (another ALS inhibitor) before it was registered and sold.
Resistant cocklebur is difficult to identify in a field setting because the resistant types are injured by DSMA and MSMA just as the normal types of cocklebur are injured.
As an example, the Missouri cocklebur was resistant to Broadstrike before it was available and is already resistant to a useful cotton herbicide that, at the time this guide was written, was still not registered for use.
