Workers act as vectors for powdery mildew
Agricultural machinery and workers’ clothing can act as vectors for transmitting powdery mildew infections from one site to another, according to research from Australia. The project, funded by the Australian Vegetable Growers Federation, also demonstrated that infections could be minimised using overhead rather than drip irrigation systems, and controlled using appropriate fungicides. The researchers also noted that infections were more prevalent in temperate conditions through spring and autumn and recommended that growers choose mildew-resistant varieties. The study demonstrates how crucial research and development findings are for growers, the federation points out.
