Corn Gluten Meal Pre-emergent
The timing for applying corn gluten meal for pre-emergent weed control is just before the weeds start to germinate. We usually guess that to be February 15 to March 15 in the South.
Liquid corn gluten meal spray - a listener/farmer recommendation that's a great idea.
The way we use corn gluten on our fields - we make a tea out of it and spray on the fields once a month from Autumn to May. Works very well. We use 2 to 6 cups of corn gluten to 100 gallons of water and spray it on with a pull behind sprayer. We just put the corn gluten meal in panty hose and suspend it in the sprayer when we fill it up, then swish the panty hose, remove and stir. Use at about 35 gallons per acre. Simple, economical and effective.
