    I have read where keeping water on a spot will keep cocklebur from growing?

    I was checking a spot that had water on it until mid or late July and it was solid burrs... And I sprayed a light amount of 2,4,D as well....

    I guess we have super burs!

    I hate cocklebur as much as the next man but never considered it to be a dirty word like this site.....

    From what I understand about 'burs, it isn't as much about how long water is on a spot and more about how quickly the water was taken off. Uneven soil moisture promotes the growth of undesirables such as 'burs and coffeebean. That's one reason, among many, why a slow draw-down or re-flood is desirable in moist soil areas, it promotes even soil moisture both laterally and vertically.

    This contains some information about 'burs and what causes them to proliferate.

    Do you know how quickly the water was taken off in July? That could explain it.

    This past spring I found cockleburs sprouting in skim water. I know for a fact the ground had not been exposed previously. I made sure to nail them with 2,4-D as soon as I could. Seen Asters sprouting in water for decades.
