Effect of Foliar Applications of Methanol, Urea and Iron on Cotton Yield in Louisiana

E. R. Funderburg, R. L. Hutchinson, T. A. Burch


A study was undertaken to determine the effects of mid-season foliar applications of methanol, urea and iron on cotton. The test was on a Gigger silt loam (Typic Fragiudalif). Treatments were: (1) check, (2) 6 gallons methanol per acre, (3) 6 gallons methanol, 0.04 lbs. nitrogen as urea, 0.16 lbs. chelated iron, and 0.25% spreader-sticker, and (4) 0.04 lbs. N, 0.16 lbs. chelated iron and 0.25% spreader-sticker. All applications were applied in a 20 gallon total mixture. Treatments were applied 6 times, beginning 2 weeks prior to bloom and applied weekly until cutout. There were no significant differences in yield between treatments, with the check having the highest numerical yield. There were also no visual differences between cotton treated with methanol and untreated plots. In this location in 1993, methanol did not influence yield, leaf size, height, or wilt resistance of cotton.
