Lyngbya Examples

 

There are few things as difficult to treat as Lyngbya, a mat-forming cyanobacterium that grows best in sand. It thrives on an environment caused by high herbicide and algaecide use and its glycoprotein sheath protects it from oxidation and chemical attack in general, often growing thicker with each treatment. But where brute force fails to weaken Lyngbya, Naturalake Biosciences uses its scientific know-how and willingness to think outside the box to find new ways to affect this tough cyanobacterium. In our lab, we conduct in-depth studies of Lyngbya‘s processes and its water environment to find potential weaknesses. We are currently studying the mediums and chemistries that affect its growth.aquastickerweb

Our previous studies of Lyngbya have led to the development of AquaSticker, an organic bacterial sticking agent. While AquaSticker does not kill aquatic plants or algae, it does make them more susceptible to attack by herbicides and algaecides. This product combines heterotrophic bacteria and a biostimulant to help reduce nutrients in waterways. AquaSticker’s technology provides a natural way to aid water clarification and prevent the accumulation of organics. It is safe to use and safe for the environment.

Below are cases where ponds found themselves attacked by Lyngbya, and applicators turned to Naturalake Biosciences and our innovative technology for help.

The Lyngbya problem in this park’s retention pond was getting worse. Every two weeks applicators would treat it with various combinations of Reward*, Hydrothol**, and copper sulfate at label rates, and a peroxide-based algaecide at up to 10 gal per acre. However, the Lyngbya would keep coming right back. Though they threw every chemical they had at this cyanobacterium, nothing could kick it out for good. With Lyngbya covering 70% of the Florida pond’s surface, the applicators sent in a water sample to the Naturalake Biosciences lab. We performed a water quality analysis to determine the conditions that allowed for Lyngbya growth and recommended dosing it with AquaSticker and Hydrothol**. Starting a treatment that included AquaSticker helped the applicators cut their chemical costs by a third. As you can see in the graph below, the simple addition of AquaSticker allowed a single algaecide to do what a combination of powerful and harsh algaecides could not. Slowly, so as not to cause a fish kill, the applicators were finally able to prevent the Lyngbya from rallying after every treatment. The applicators and Naturalake Biosciences together were able to replace the dark, ugly mat of algae with a much more pleasant sight of the clear blue sky reflected in the water.

In this 5-acre pond applicators began treating every two weeks with the conventional treatment. After receiving lab testing from Naturalake Biosciences they switched to AquaSticker and Hydrothol**, which reduced the amount of surface area covered in Lyngbya to 1% within 4 treatments.

This pond hadn’t given applicators any major problems for twelve years. But its position 1 mile from the ocean put it in the flood plain, and sure enough, a heavy summer rain flooded the pond. This one rainfall managed to change the nutrient load of the entire pond, a change which gave Lyngbya the opportunity it needed to create the situation seen above in the left image. Our water quality analysis showed that the new pond nutrient load contained high levels of nitrate, orthophosphate, and iron that fed the Lyngbya growth. For these nutrients we recommended MD Pellets, and to take care of the existing algae we recommended Hydrothol** and AquaSticker. The image above on the right shows that 2 months later, the last of the Lyngbya was dying off.

Lyngbya was taking hold in one of this Home Owners Association’s 100 retention ponds. Residents began complaining that their pond was covered in algae and the rest were fine. This, combined with Lyngbya’s inherent toughness meant the applicators ran into the danger of spending their entire budget on a single pond. In one month they spent roughly $2,500 trying to get rid of the Lyngbya. We thought we could help. After Naturalake Biosciences lab testing, we prescribed them AquaSticker and Hydrothol**. This treatment took care of the Lyngbya and kept it away without spending the applicators’ entire budget.
