Free Floating Weed Control - 2 x 1L
Free Floating Aquatic Weed Control for Azolla, Duck Weed & Salvinia
Free Floating Weed Control Spray for the control of Salvinia, Duckweed, Lemnaand all types of Azolla in irrigation Dams, Farm Dams & Ponds.
Free Floating Aquatic Weed Control Spray 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 Aquatic 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 Aquatic Weed Control effects floating aquatic weeds in various ways, for Duckweed and Lemna it partially removes the wax coating on the leaf, thus reducing the leafs buoyancy. In the case of 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 Aquatic 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.
DIRECTIONS
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 Aquatic Weed Control, it is beneficial to apply several light applications over 1- 3 week period, instead of one single heavy application.
Free Floating Aquatic Weed Control is most effective when the infestations are smaller rather than advanced.
To ensure that the water 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 water 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.
APPLICATION RATES
1L of Free Floating Aquatic Weed Control treats up to 500m2 of water surface area, depending on the density of the floating aquatic weeds.
To apply mix one part Free Floating Aquatic 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.
YOUR GUIDE TO IDENTIFYING & CONTROLLING FREE FLOATING AQUATIC WEEDS
There are three common types of Free Floating Aquatic Weeds
- “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 water 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.
- “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 water surface. If not treated it can double in numbers within seven days.
- Salvinia
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.
HOW TO CONTROL FREE FLOATING AQUATIC WEEDS
Free floating aquatic weeds such as duckweed, lemna, azolla and in particular salvinia can be difficult to eradicate due to their rapid growth rates.
Effective methods of treatment can vary depending on the level of infestation. Treatments are most effective when the infestations are smaller rather than advanced.
Spray treatments are most effective when the infestations are smaller rather than advanced. A combination of both a spray treatment and physical removal is best when the infestation is advanced and is covering 90 -100% of the water surface.
