Since Environmental Factor received pre-emergent weed killer licensing for their Corn Gluten product, called Turfmaize, the price of corn gluten has gone up significantly. Some competitors have offered a non-licensed, ‘watered down’ version of Corn Gluten with various fillers added. By the terms of its license with Health Canada’s Pest Management Regulatory Agency (PMRA), Environmental Factor’s Turfmaize is at least 98% pure corn gluten. For 2011 we selling our 9kg bags at $29.99, our 20kg bags at $44.99 and our 25kg bags at $54.99 each. We are keeping the price of this item affordable to try to entice as many people as possible to use a safe and environmentally friendly alternative to synthetic weed control products (now banned in Ontario). 9kg will treat 1000 square feet (approximately 90 square meters). Corn Gluten is a product which is best applied in early spring (due to the late spring you still have time) once the lawn can be safely walked on (the ground doesn’t feel spongy) and late summer/early fall before the weather cools and the weeds germinate. The city of Ottawa's website also suggests an early summer application. Need a spreader? Make It Green will lend you one (free) as long as you are applying organic products.
