Diseases caused by Sclerotinia spp., generally known as 'white mold', can affect hundreds of plant species including many important crops. The pathogens are favored by cool, moist conditions, but show surprisingly broad ecological distributions. 1 Several other Sclerotinia species cause diseases other than white mold.
Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. The primary source of oxygen for a pond is from microscopic algae (phytoplankton) or submerged plants.In the presence of sunlight, these produce oxygen through photosynthesis and release this oxygen into the pond water.xygen dissolves in water at very low concentrations. Our atmosphere is 20% oxygen or 200,000 ppm but seldom will a pond have more than 10 ppm oxygen dissolved in itsâ water. Dissolved oxygen concentrations below 3 ppm stress most warmwater species of fish and concentrations below 2 ppm will kill some species.
We carry other products that will control algae during the time that your pond is maturing. Algae Fix is probably the most effective. Barley Straw and Barley Straw Extract can also be effective in improving water conditions for most ponds. Pond Dye shades the water, which limits the amount of sunlight feeding the algae.We carry blue and black dye, this is a cost-effective solution in large ponds and lakes, but it can be used in any pond. If your pond does not contain fish then Fountec is a great product to use.his type of algae cannot be totally eliminated with fish and plants in the pond. String algae, which may coat the waterfall, is a little harder to control. You can physically remove it from the pond where possible.
