In experiments conducted on California lawns, corn gluten meal did not provide satisfactory weed control. A standard guide is to remove no more than 1/3 of the leaf blade at each mowing. Soil compaction restricts the flow of oxygen, water, and nutrients into the roots, causing the turfgrass to grow slowly and making it more susceptible to weed invasions. Triclopyr, the active ingredient in Turflon Ester Ultra, tends to stay where it is applied, so it is not likely to move through soil and reach the roots of off-target ornamentals or vegetation.

Corn gluten meal has no effect on already emerged weeds. A lush, unbroken expanse of bright green lawn is a lovely thing to behold. Calif. Agric. However, corn gluten meal may help in weed management because its high nitrogen content acts as a fertilizer, which makes the turfgrass more competitive with weeds. With preemergence products, this means relying upon weed populations observed last season. If not controlled before they flower, they can produce seed that will sprout the following year or sometimes in the same growing season. Use a thatching rake on small lawns to loosen the layer of thatch. Turflon Ester has been around for a long time.
