Using Corn Gluten for Weed Control

This is a natural substitute that works as well for chemical pre-emergent herbicides; the seeds ability to germinate should be interfered by corn gluten meal, so it makes them not practical. Its used as a natural pre-emergent herbicide and was accidentally discovered during research on turf grass diseases. 50 to 60 percent of weed seeds can be controlled when applied at 20 lb. per 1,000 square feet. The application ratio changes with the intended use, but you can achieve the satisfactory control of weeds at any recommended rate of application. It obtains a higher percentage of weed control for several years.

If you are considering using corn gluten for controlling weeds, here you can find the steps to do it that work very well. So, let’s check this out!

    1. A drop spreader should be used to fill with granulated corn gluten; it is available in several brand names. 12 lb. for each 1000 square feet should be used in lawns by the application rate for the control of crabgrass. When applying the ratio, the spreader should be set; the instructions of the manufacturer of the drop spreader should be followed.

  1. By using the drop spreader in early to mid-spring for the most effective preemergent weed control, the corn gluten can be applied now. You can walk across the lawn by using the drop spreader. Missing a spot can be avoided by walking in straight rows, slightly overlapping every pass.
  2. A second pass, walking in a direction perpendicular to the direction you walked first should be made. Overlap  each pass, so the bare spots will be avoided.
  3. The second application should be made in early to the middle of august. The newly formed seeds will be prevented by this second application from germinating. The number of weeds will be prevented by this in subsequent seasons. The same procedure that is used in the early spring application should be applied to use.

Discovery

Using Corn Gluten for Weed Control

Using Corn Gluten for Weed Control

The newly seeded grass samples were be treated by the turf disease researchers at Iowa State University with fungus laced corn gluten meal in 1986. The corn meal was only a cheap medium for the fungus, but the researcher were surprised by it, the seed germination was also prevented. The fungal study was abandoned by the researchers and then they started focusing on corn gluten.  And finally the natural pre-emergent herbicide was patented in 1991.

A chemical barrier across the soil should be created by the proteins from corn gluten meal; the root growth is prevented in germinating seeds. The nascent seedlings, without the ability to get water will quickly die. Certainly the results vary, the herbicide that stops 60 to 90 percent of weed seeds should were shown by the research. Maybe a better result can be had by the inorganic herbicides, but naturally and successfully weed control can be done by the corn gluten meal after the consecutive treatments.
