When to Apply

Successful pre-emergence control of the annual grass weeds listed on this label requires proper timing of application. Apply this product 1 to 2 weeks prior to the germination of annual grass weeds. If application timing does not coincide with the normal germination period of any of the annual grass weeds listed on this label, weed control results may be erratic or poor. Weed seeds typically begin to germinate when soil temperatures reach 55 degrees Fahrenheit (3 to 5 days of 60-65 degree weather can change your soil temps). Typically applied mid-march in most areas, gauging your weather is the best practice when applying pre-emergents. Remember if you can see the weed, pre-emergent controls will not help. Apply before a light rain or lightly water the product in.

Application Rates:

Apply 3 to 4 lbs. per 1,000 sq.ft. – If you have an issue with weeds, we recommend 4 lbs. per 1,000 sq.ft. as a treatment and 3 lbs. per 1,000 sq. ft. as a preventative.

Things to remember when controlling weeds:

  • Anytime you treat for weeds it is important to make sure you overseed the lawn or the area the following season.
  • Weeds love weak spots in the lawn, if you are treating weeds in an area that is already weak and your remove more weeds you are creating the perfect spot for more weeds. To keep a healthy, thick and growing lawn it takes work especially in the beginning. Control your weeds, continue to fertilizer through each season and overseed when it is best for your area for best lawn results. Once your lawn is doing better after all of your hard work, weed controls aren’t always necessary so you can focus on fertilizing at least 3 times a year (we recommend 5 application) and spot seeding in any areas that may need it after possible seasonal damage (seeding in Fall is best, spring if needed).

Don’t use Inhibitor on newly seeded lawns. You can seed the following season (Control in the spring, seed in the fall).

Product Description

TurfMaize is available in Canada only. For USA we suggest LiquiGold.

Corn Gluten Meal is a by-product of the wet-milling process of corn grain. This process separates the components of the grain to obtain starch and other valuable organic materials. The Corn Gluten Meal is the protein fraction of the corn.

Corn Gluten Meal must be applied before weed germination. The standard recommended application rate is 21 pounds of product (2 pounds N) per 1,000 square feet in the spring in a two-to-four week period before the germination of summer annuals like crabgrass. It is recommended that you time your spring application when the Forsythia begins to bloom or up to two weeks prior to the show of colour of your crocus, early daffodils, and early tulips. These flowers bloom about the same time that some common weeds germinate. The timing of the application will vary with the weather. Your Crabgrass will germinate when your soil temperatures have reached 55 degrees F.

This organic form of nitrogen will be released slowly throughout the summer. Corn Gluten Meal can be also be applied throughout the summer on actively growing turfgrass at rates of about one pound N per 1,000 square feet per when adequate moisture is being supplied throughout the summer. The second application of 20 pounds of nitrogen per 1,000 square feet on cool-season turf is made around August 15 to September 1st. This helps control some of the perennial broadleaves and winter annual weeds that germinate in late summer and early autumn. This also provides 2 pounds of nitrogen to your lawn slowly through the fall. Apply Corn Gluten Meal only when the soil is moist and rain is forecasted within 2 days of application. If it does not rain within 2 days of application then you must water your turfgrass.

Areas with high populations of Crabgrass will be reduced by about 60 percent in the first year of application. In the second year of application it will be reduced by about 80 percent or better. Reductions of 90 percent can be achieved by year three. There is no carryover of the pre-emergent effect of the Corn Gluten Meal. Its effect generally dissipates in five to six weeks after it is applied. The cumulative effect of the repeated applications is to thicken the turfgrass. This is a natural inhibitor to the germination of weed seeds and Crabgrass. To maintain this the thick stand of turfgrass it must also receive adequate amounts of water on a timely basis throughout the growing season. Corn Gluten Meal prevents the young sprouting seeds from developing normal roots. The common weeds that are affected by Corn Gluten Meal are Crabgrass, Creeping Bentgrass, Smart Weed, Dandelions, Red Root Pigweed, Purslane, Lambsquarter, Foxtail, Barnyard Grass, and Bermuda Grass.
