Production nurseries require a water supply that is reliable, low in cost and of excellent quality. To achieve the water quality demanded by nursery production, most water sources will require some level of disinfestation. This fact sheet compares the advantages and disadvantages of various disinfestation treatments.
Using ultra violet radiation and chlorine dioxide to control fungal plant pathogens in water.
Sodium or calcium hypochlorite (Chlorine) is frequently used within the nursery industry in Australia for the disinfestation of water used for nursery irrigation. It has proved suitable for most applications within the industry and is generally considered effective, simple to use, easy to monitor and relatively safe to handle and store.
Slow sand filtration is a low-cost water disinfestation method that can be used as an alternative method of treating nursery irrigation water to control plant pathogens. It is a method that has gained popularity for use in treating recirculating nutrient solutions in greenhouse production yet can be adapted to large scale water treatment in nurseries.
The most significant raw material to the human race is water. Water in its clean, uncontaminated and unpolluted form is colourless, odourless and tasteless.
The growth of algae in water storages can cause significant problems with pumping infrastructure by increasing the clogging of filters and emitters. Algae also reduce water quality by increasing pH levels, in turn reducing the effectiveness of water disinfestation treatments. The fact sheet looks at algal species that may be present in water storages and…
