Safe ‘n Simple® Pre-emergence Weed Control 9-0-0 is an all-natural plant product made from Corn Gluten, a dried protein separated from corn during the manufacture of starch in the food industry. Corn Gluten is a common ingredient used in pet food. In 1985, while studying its value as a fertilizer, researchers at Iowa State University discovered that Corn Gluten contains a natural organic compound which inhibits root development in seedlings. Germination occurs, but seedlings die from lack of a root system. The result is an environmentally safe, non-toxic, completely natural weed control.
Pre-emergence Weed Control 9-0-0 provides weed control and an excellent source of slow-release nitrogen, in an easy
to spread crumble form. When spread at the recommended rate it provides 4 lbs. of nitrogen/1,000 square feet. Nitrogen is released as micro-organisms break down in the soil.
For best results, apply in early spring to control crabgrass and again in late summer. Many broadleaf weeds, including dandelions, germinate and establish root systems in the fall in preparation for spring growth. In addition to crabgrass and dandelions this product controls the germination of creeping bentgrass, smart weed, redroot pigweed, purslane, lambsquarter, foxtail, barnyard grass, and Bermuda grass. Pre-emergence Weed Control 9-0-0 is easily applied with a broadcast spreader. The recommended application rate is 20-lbs per 1,000 square feet.
Pre-emergence Weed Control 9-0-0 can also be used around shrubs, flowers, and vegetable plants that have an established root system. Mix product into the top 2” to 3” of soil at the rate of 2 lbs. (6 cups)/100 sq. feet, repeating 2 to 4 times per season as needed. Product remains active in the soil for 3 to 6 weeks depending on temperature and pH.
