On behalf of the Crop Protection Association I would like to add to the debate on microbial inoculants and their alleged control of turf diseases. If you read the adverts on page 27 and page 29 of the July 2000 issue of International Turfgrass Bulletin, you would believe that these bacterial and mycorrhizal fungi products control turf diseases. Whether this is true or not, one fact remains absolute. If a product is biologically active against any weed, pest or disease and can be used to exert control over them, then it is defined by European and national legislation as a pesticide (the only exceptions being beneficial predatory insects and nematodes used for the control of insect "pests").
