Thanks for info, neat! Most problem weeds on the prairies where I farm are taller than the planted crops when mature, particularly as yield benefits have been gained by shortening more and more varieties over time. A pigweed or a smartweed will outrun a wheat crop with a week of head-start like nothing. Corn can't take any competition at all, I had a planter row in my Barley of corn one year, I figured the corn would simply outgrow the barley and leave it in its proverbial dust.. quite the opposite, I sprayed the Barley out at about the 4-leaf stage and the corn was a full 2 feet shorter than the row beside it at maturity! That all said of course a natural prairie is different, the tall-grass prairie - as far as I understand it - competes for water under the ground more than light above it - shade can actually help! (Lord knows I mow under my trampoline twice as often as the rest of the lawn.)
