BAIT SNAILS NOW: Grain growers who need to control snails through baiting must do so soon. All baiting must be completed by late August or at least two months before harvest, according to the South Australian Research and Development Institute (SARDI) Entomology Unit. SARDI entomologist Kym Perry says very high snail populations this season increase the risk of snails becoming a grain contaminant at harvest, potentially clogging machinery or leading to downgrades. “The next few weeks are the last opportunity to bait to reduce snail populations prior to harvest, therefore now is the time to monitor and assess the need to bait,”
said Mr Perry, whose work is supported by growers and the Australian Government through the Grains Research and Development Corporation’s (GRDC) investment in the National Invertebrate Pest Initiative (NIPI). Baiting must be finished at least two months before harvest to ensure bait has broken down and does not itself become a contaminant, for which tolerance is zero. “After this time, harvest techniques such as windrowing of some crops, header modifications and post harvest grain cleaning are the only options to reduce contamination,” Mr Perry said. He advised growers to carefully inspect all parts of all paddocks for live snails. “Crop perimeters and fence lines should be checked, particularly next to roadside verges from where snails could reinvade paddocks. Any areas with sufficient numbers to cause problems at harvest should be baited when conditions are moist.” More information on integrated snail management is contained in the GRDC publication Bash 'em, Burn 'em, Bait 'em.
