| Aquatic herbicides and algicides have been used successfully for several decades. |
|
| Allelopathic algicides are regarded as potential natural resources to constrain HABs for their exclusive and efficient characteristics. |
|
| As well, use of algicides would kill all algae, giving cyanobacteria less competition in a subsequent growth phase. |
|
| These may be used as algicides, bactericides, invertebrate pest control, fungicides or wood treatments. |
|
| Process for the treatment of water with algicides, characterised in that chlorhexidine or a salt thereof is used as algicide. |
|
| Salt electrolysis systems are fully compatible with any other treatment aids such as flocculants, algicides, cyanuric acid etc. |
|
| One must generally know that algicides have a preventative effect and only work if there is the right amount of algicide in the water. |
|
| Algae growth is generally prevented by using algicides. |
|
| Spraying of systemic fungicides was found to be superior to biocontrol agents followed by algicides in controlling the disease under field condition. |
|
| However, algicides such as copper sulphate-based products or quaternary ammonium chloride-based products may sometimes be required to tackle specific algae problems. |
|
| There is a variety of chemical treatment methods available using different classes of bactericides, fungicides, algicides and buffers or corrosion inhibitors. |
|
| The PMRA reviews applications for registration of algicides on the basis of scientific information to assess hazards to human health and the environment in addition to product efficacy. |
|
| Note that algicides do not control disease-causing microorganisms. |
|
| In some cases, the label directions of swimming pool sanitizers and algicides may instruct residential pool owners to maintain a minimum chlorine level of 0.6 ppm. |
|
| To date, studies on the effects of these algicides on HAB species have mainly focused on the biocidal efficiency, by measuring cell growth, pigment content, and photosynthetic efficiency. |
|
| This means that the catfish must be free of antibiotics, synthetic algicides, and land-animal byproducts in feed. |
|
| Antibiotics, fungicides, parasiticides, algicides and pesticides are used to control diseases inside the crowded shrimp ponds. |
|
| This formula can reduce the use of chlorine up to 60 percent and decrease or eliminate the need for scale removers, algicides, clarifiers, filter cleaners and acid washing. |
|
| With waxes to waterproof, algicides to stop the growth of green algae and UV filters to prevent colour fade, this is the ultimate treatment for fences. |
