Show All Answers

1. What can I do to get rid of the dandelions blooming in my yard?

When dandelions are blooming in the spring, it's already too late to get effective control with herbicides. The best control at this time is hand digging. Dandelions are a winter annual that germinate in the fall, winter over, and produce seed in the spring. A chemical application of 2,4-D in the fall will give nearly 100 percent control.

2. What weeds are considered noxious in Riley County?

There are five weeds declared noxious which are located in Riley County: Musk Thistle, Field Bindweed, Johnsongrass, Hoary Cress and Sericea Lespedeza.

3. Can I purchase brush herbicides from the weed department?

No, Riley County can only sell herbicides for noxious weed control. We can make recommendations, but you must purchase the herbicides from your local dealer.

4. Do I need an applicator's license to purchase chemicals for noxious weed control?

You only need a license to apply a restricted use pesticide (RUP). The only RUP that we sell is Tordon 22K. You must have a private applicator license to apply Tordon, but you may purchase the product and have a commercial applicator apply it for you if you are not licensed.
