Aqua-Weed Control has been managing our aquatic nuisance plants for over 50 years. Dick Pinagel and his staff have been advising as to the best way to manage our water quality and filing all of the permits with the state for treatment.
When do we spray? We are often asked to publish the dates we will be spraying the lake. There are many factors that go into making that decision that prohibit a definitive timeframe. Weather is one of the biggest factors. A sunny, hot spring will warm the lake faster and bright sunlight helps to promote growth.
Swimming and watering after the lakes have been treated Sylvan Otter Lake Association receives several calls each year stating, I just went swimming and then I saw the posted signs for treatment, do I need to see a doctor?
Or, our sprinkler system is automatically set to water and I was out of town when you sprayed. Am I going to kill my yard?…, more chemicals and process
The state government regulates chemical use for weed control, especially the degree to which certain chemicals may be introduced into Michigan lakes for weed control.
We are using the least amount of chemicals in the lakes as possible, but enough to be effective. These have proven over the years to be safe.
To give you a better understanding of the amount of chemicals used, they are administered into our lakes in only the needed areas at a rate of between 1 and 5 parts per million, depending on the specific chemical.
