snail control

Catalogue: GRDC Updates
Baits do kill juvenile snails... Stubble and/or green plant material reduce uptake of snail bait by juvenile snails... After three days, any remaining baits were removed and weighed to determine amount consumed and snail mortality was assessed after another five days...

A snail bait distribution trial on Yorke Peninsula in 2013 tested the coverage of various spreaders and found that on average coverage was two-thirds of that expected with urea... Recent rains across much of south-eastern Australia have led growers to look at controlling snails and slugs due to an increase in their activity, meaning now is the ideal time to spread bait... "Research is still continuing into the effects of fragmented baits, but it is unlikely that these smaller fragments would contain a lethal dose, so I would recommend that when growers do their calibration run, they look for fragmentation - where instead of baits there are small crumbs - and increase the dose assuming that those baits are no longer effective...

Snails are in such numbers on some farms taht they have clogged up harvesting machinery... "If there is sufficient food and moisture, snails will descend from their summer resting places and may breed opportunistically," Mr Shannon says... Mr Shannon says that in addition to baiting, an integrated approach to snail control may include the following: good summer weed control; using mechanical controls, such as towing a cable or roller behind a tractor if hot, dry conditions persist; and uniform burning, which can also help to effectively control snails, but should be avoided if other options are possible...

In-paddock imaging technology is being employed in research which aims to help growers better predict when slugs will be active on their properties, so they can better time baiting applications... The research is being conducted as part of a project investigating slug and snail monitoring and control methods, initiated by the Grains Research and Development Corporation (GRDC) Regional Cropping Solutions Networks (RCSN) initiative... Due to the sporadic nature of slug attacks, Ms Micic said the RCSN study had set up a field trial at Frankland with imaging technology to take photos every few minutes, along with a weather station, to correlate environmental cues with slug movement...

Mediterranean white and conical snails will serve as test subjects in a pilot study that may lead to the adoption of gene-silencing technology for crop pest-control applications... Dubbed "daughterless technology", the strategy involves constructing a molecular switch that can turn off female development, creating male-only populations... Existing controls have proved only partially successful and involve practices that are increasingly unacceptable to growers, because they either promote soil erosion (such as stubble burning) or cause chemical contamination (pesticides)...

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 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)...

Time to intensify snail control measures.. "It is critical that baiting or other forms of control are activated as close as possible to a rainfall event... The workshop in Adelaide - attended by GRDC panel members and program managers, entomologists and researchers from South Australia, Victoria, New South Wales and the Australian Capital Territory, grain growers and consultants - was told that juvenile snails which survived over summer should be mature enough now to consume bait...

In addition to baiting, other practices should include: "Snails have become a very serious issue in recent seasons, causing crop damage and yield losses, clogging machinery, contaminating harvested grain and posing a risk to grain exports," Mr Shannon said...
