An innovative new product from Scotts Algae bloom
‘clogging up’ of infrastructure that is designed to carry water or store it. This also causes a significant reduction in water flow increasing the risk of flooding in the event of heavy rainfall. If the capacity of the pool needs to be restored then the best option for remediation is dredging. This, however, is very costly as a form of weed control for which a foliar application of herbicide is the recommended method. Generally, mechanical control is highly destructive in terms of the habitat that is literally being removed. This gives the invertebrates no time to leave and re- establish elsewhere and, more likely than not, leaves them high and dry on the bankside exposed to passing predators. Foliar herbicides, applied by qualified, skilled operators are the most effective and least invasive solution.
Herbicides cause a slow die back of the vegetation allowing any fauna to migrate to other habitats within the pond. Well timed applications of Roundup Pro Biactive will achieve control only if the criteria and conditions for application can be met.

The red tide
Many water courses have suffered from seasonal algal blooms that are caused by a combination of conditions. The floating algae that cause blooms are a natural part of the water flora but, due to high nutrient availability in the pool, can reproduce rapidly generating the bloom. Algae that bloom often cause an unpleasant odour as well as making any water feature look unsightly. The best management control is to manipulate the availability of the nutrients that enable the bloom. If they are frequent, a change to your fertiliser regime to lower the flow of nitrogen and phosphorous into the pool will limit the ability of the algae to bloom. If this is not an option, successful control can be achieved with ultrasonic equipment that disrupt the algal structure, causing the algae to die. Dyes that can be added to the water to prevent growth have shown some merit, though the change in colour may not be to the members’ tastes. Herbicides are not advised as a solution as they provide a very short term period of control.
- Pro Crystal will give swift control of algal blooms in enclosed lakes. It is a novel combination of micro organisms that process the nutrients that the algae thrive on, removing them from circulation. This modifies the nutrient status of the pond preventing the algae from blooming. Results are good and last for up to three weeks. The best longer term option, in addition to reducing nutrient availability, is Barley straw. This technique has been used successfully for many years as a low input low maintenance natural option. The straw is rolled into a sausage and then placed in the pond - simple and effective!
MANAGING weeds in a highly sensitive environment such as water is skilled specialist work. Acute awareness to the consequences of treatment and thinking ahead are essential to achieve, not only the result that is desired, but causing no harm. There are several cases of operatives treating weeds in streams unaware that lower down the stream the water was abstracted for agricultural irrigation. As you can imagine crops do not usually respond well to irrigation with weak solutions of glyphosate! It is care and attention to detail that is needed when applying herbicides in this sensitive environment. It is the man behind the nozzle that makes the difference!
