The March 21 newsletter contained an error in the winter wheat section with regard to the recommendation for Ally plus 2,4-D. The correct rates are Ally at 0.1 ounce/A plus 1/2 pint of 2,4-D ester.
No-Till Weed Control
Weed control is a key to success with no-till crop production. Control of weeds established at planting time as well as later developing weeds is required. New developments make economical, effective weed control programs available for most situations. One approach is to combine a postemergence and a residual herbicide applied at planting time. Another is to make an early preplant application of residual herbicide and eliminate the postemergence herbicide.
Weed Control in New CRP Seedings
2.4-D ester is an economical choice to control broadleaf weeds at least" one month before seeding grasses or 1equmes. Use 1 pint/acre for most small broad1eaf weeds; increase the rate to 2 pints/acre if large weeds are present at application. Remember that 2,4-D can persist in the soil for up to 4 weeks after application and it may injure grass seedlings and legumes if applied within 30 days of planting.
