The physical removal of free floating Azolla and Salvinia has several advantages particularly when infestations are advanced. Partial physical removal increases the effectiveness of spray applications, such as Free Floating Weed Control by reducing the amount of spray being applied and speed up the overall treatment process. Partial physical removal or bulk physical removal takes out the nutrient loading held within the Azolla or Salvinia. The Azolla and Salvinia Skimmer is specifically designed to make the job of physically removing Azolla and Salvinia quick and easy.
Safe and simple to use, the skimmer reduces the OH&S risks with its easy action to capture Azolla and Salvinia and remove it from the water. Each sweep, captures a path using a tailored screen mesh and as the skimmer is removed from the water it closes and traps the catch, for easy disposal onto the shore line or into a wheelbarrow or trailer. The skimmer clears a path of 1.52m wide with every sweep and is ideal for ponds and dams.
Plus Bonus Package Includes:- FREE FLOATING WEED CONTROL
It is a natural product based on orange oil extracts that is safe and easy to apply. It does not affect other aquatic plants and treated water is safe for use, as there is no withholding period. Water bodies treated with Free Floating Weed Control, are safe to use for irrigation and stock watering purposes and it is safe for fish, pets and wildlife as it is not a herbicide.
Free Floating Weed Control effects floating aquatic weeds in various ways, for all types of Azolla, it partially shrivels the tiny hairs on the leaf which trap air to keep them afloat. For Salvinia it effects both the wax coating and the tiny hairs that trap air.
In all cases Free Floating Weed Control effects the surface tension of the water, thus reducing buoyancy for all types of free floating aquatic weeds, making them lose buoyancy and sink in the water column and die.
Suitable for the control of Salvinia, Duckweed, Lemna and all types of Azolla, in lakes, dams, irrigation channels, water storages and ponds.
Depending on the density of the Free Floating Weed Control, it is beneficial to apply several light applications over 1- 3 week period, instead of one single heavy application.
Free Floating Weed Control is most effective when the infestations are smaller rather than advanced.
To ensure that the waters surface tension is effected, ensure that all for the open waters surface is treated. In areas where there is no free floating aquatic weeds, apply lightly but evenly.
If the infestation is advanced, an increased product to water mixing ratio can be used to increase the strength of the application.
If the infestation is advanced with 90 -100% coverage of the waters surface area, it is recommended that some of the free floating aquatic weeds are physically removed to create free water, to allow the free floating aquatic weeds to be able to sink effectively.
The smaller skimmer clears a path of 91cm wide with every sweep and is ideal for ponds and dams.
Your Guide to Identifying & Controlling Free Floating Aquatic Weeds
There are three common types of Free Floating Aquatic Weeds
1. “Duckweed” or Lemna
Duckweed is a very common, tiny, free floating aquatic plant, with leaves varying from less than 1mm up to 1cm in size. Duckweed appears as a green cover on the waters surface and is an indication of nutrient-enriched conditions. It grows rapidly in stationary and slow moving water bodies, especially where nutrient levels are high. If not treated, it can double in numbers within five to seven days.
2. “Azolla” / Red Azolla / Green Azolla or Ferny Azolla
Azolla is another common free floating aquatic plant, with leaves varying in size from 1 to 2.5cm in diameter. Azolla appears in a greenish shade and can turn a reddish shade in the late afternoon or when exposed to full sunlight over a period of time. Azolla has a fern type leafed appearance with roots trailing below the waters surface. If not treated it can double in numbers within seven days.
Salvinia is a declared noxious free floating aquatic weed, in all states of Australia, with the plant measuring up to 20cm long and leaflets of 0.5-3cm wide. The leaves are covered with hairs that repel water and keep it from sinking. Salvinia is capable of choking a water body, it multiplies by fragmentation and can double the area it covers in five days. If not treated it can take over a water body, kill fish and rapidly affect water quality.
FFWC Application rates:
1L of Free Floating Weed Control treats up to 500sqms of water surface area, depending on the density of the floating aquatic weeds.
To apply mix one part Free Floating Weed Control with 100 parts water and spray using a back pack sprayer or hose directly onto the free floating aquatic weeds and around the adjoining open water surface.
FFWP Application rates:
To assist in preventing the return of Azolla, Salvinia & Duckweed, apply 100ml per 100 square metres of water surface area & reapply every 4-6 weeks, or as required.
When used in conjunction with Free Floating Weed Control, apply Free Floating Weed Preventative 2 hours after you have applied the Free Floating Weed Control. Apply at a rate of 125ml per 100 square metres of water surface area.
Apply Free Floating Weed Preventative 4 days after the application of approved herbicides at a rate of 100ml per 100 square metres of water surface area, reapply every 4-6 weeks or as required.
