| Located in North Central Ky. Crop consultant said pint to the acre. That just seemed light to me for killing 6 to 7 ft tall waterhemp. The beans are an early maturing variety (3.9 planted on April 19). It will be 4 to 6 weeks before a potential killing frost. My fear is the beans will be flagging and head shatter will be an issue if I try to wait on a killing frost.
Before the I get fired up for letting waterhemp get that big, I tired just about everything to stop it. This is river bottom ground that floods every winter. It is hard to controll the seed bank. I used a pint of 24d (lv6) 44 oz of round up, 7 Oz authority xl and 1 oz of sharpen at burndown, 3.5 quarts of flextar GT with 2 oz of zidua over the top. We have had a lot of rain here this summer. I think the pre and post residuals lost there effectiveness and by being washed out. Some of the beans were 2 to 3 foot tall and canopied when the water hemp broke through. Beans were planted in 15 inch rows, 146,000. | |
