Abstract
Description
Cattail growth in lakes, wetlands, lake edges and drainage ditches in North Dakota is discussed. While part of a natural ecological environ, cattails can strangle out waterways, reduce oxygenation and microbial activity in these waterways. Therefore, cattails become a weed and, thus, must be controlled. Typical ways of crushing, mowing, burning and discing to control or to reduce cattail presence are short-lived and ineffective. Herbicides have proven the most effective method of controlling cattails infestation. Several trials were made spraying cattails with glyphosate at various stages of growth with various amounts of chemical. Late July to early September appeared the optimum period to apply the chemical. The amount of glyphosate appeared immaterial.
