How To Kill Azolla Weed Very Well

August 7, 2017 in Garden Pests and Diseases by Christine

Problem azolla weed control

How To Kill Off Persistent Azolla Weed Very Well Azolla, also known as Water Fern or Mosquito Fern, is the fastest growing freshwater plant. The symbiotic association of Azolla with blue, green alga Anabaena provides it with nitrogen, which helps the plant to grow its biomass very fast. Azolla floats on water with its small scale-like leaves and their roots under water. This plant can colonize the freshwater areas at great speed. They are used as bio fertiliser, but are considered as a weed as they entirely cover the water bodies. Depending on the exposure of the plant to the sun, the Azolla can appear green or red in colour. The excess growth of the plant can block the water pumps and their filters. Azolla in water bodies can reduce the oxygen content in water. Therefore care should be taken to control the weed, if the Azolla weed is not treated and takes over. Beyond a doubt, it can kill off live fish and frogs spawning eggs masses.
