Parrot’s feather: Biological control using plant pathogens
A study in South Africa (Morris et al. 1999) reported that parrot’s feather Myriophyllum aquaticum plants treated with a strain of the bacterium Xanthomonas campestris did not die. After treatment with a suspension of the bacterium all parrot’s feather sections above the water died. However, after six weeks new shoots developed from the submerged stems leading to plant recovery. No data or statistics were reported. Plants were sprayed with a suspension of the bacterium at a concentration of 108 colony-forming units/ml. Authors do not report where or when the trials were conducted.
