Don't let snails eat into your crop profits.. "Controlling summer weeds is important as it means that snails are more likely to eat baits, which should be applied before snails lay eggs, which occurs generally in late summer or early autumn," she said... "Snails causing damage to WA crops are predominantly small conical snails, although round snails are also a problem at Esperance, Hopetoun and in parts of the Geraldton port zone," she said...

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...

Snail biocontrol trial results fast-track new weapon for growers.. Dr Ash said the biocontrol was just as effective as the metaldehyde bait when applied in high levels, and offered a reasonable level of control at the low rate... Nematodes have all the characteristics of a perfect biocontrol agent and they have been successfully developed for the biological control of other invertebrate pests in Australia," Dr Ash said. "..

Western Victorian harvest faces snail contamination risk.. If snails are present in crop canopies or windrows at harvest time, the options available to growers to reduce snail contamination are limited.".. Dr Umina said strategies to reduce snail intake are generally more effective when applied early in the harvest season when fewer snails are present in the crop canopy, snails are more easily dislodged from plants with lower grain losses, and they still respond to moisture events by descending down the plant canopy to resume feeding...

Reducing snail contamination a priority this harvest Grain growers in South Australia face a heightened risk of snails contaminating grain this harvest, resulting in potential downgrades and clogging of machinery... Options to reduce snail contamination are limited to minimising the intake of snails into the header, maximising the separation of snails and grain within the header, and post-harvest grain cleaning. ".. Sheet metal (punch-hole and expanded mesh) sieves are usually more effective than louvre sieves in removing snails but have a lower cleaning throughput harvest speed may need to be reduced to avoid overloading and grain losses...

Snails break into SA growers' holiday plans - By Emma Leonard.. Snails are the latest challenge for growers on SA's upper Eyre Peninsula, where the 2011 harvest was significantly affected by the pest... The common white and conical snails are a new threat to crops in this region, with the level of concern reflected in the fact more than 150 growers gave up part of their January holidays to attend information meetings...

In desperation we began to employ numerous ways to control snails but without ever being able to break their life cycle... We have used the machine on all grains including wheat, barley, lentils, beans and peas... The last two years have been very bad for snails on our farm, but because we have concentrated on controlling snails before seeding, we have not had to rely on the Inclined Belt to deliver our canola...

Control snails this autumn to prevent crop damage.. Western Australian growers who had snails present in 2012 harvest samples or who have found the pests on soil beneath stubbles are urged to implement management practices including baiting this autumn... "Snails causing damage to WA crops are predominantly small conical snails which are suited to all soil types, and cropping areas where snails are most problematic include south coastal districts and some areas near Geraldton," she said...

The South Australian Research and Development Institute (SARDI) Entomology Unit warns that snails present above cutting height in the canopy or in windrows can enter the header during harvest, potentially leading to clogging of machinery and grain quality downgrades... "At this time of year, the aim is to minimise the intake of snails into the header, maximise the separation of snails and grain within the header, and where necessary, clean harvested grain to minimise the number of snails eventually entering the grain sample," Mr Perry said... Sheet metal (punch-hole and expanded mesh) sieves are usually more effective than louvre sieves in removing snails but have a lower cleaning throughput harvest speed may need to be reduced to avoid overloading and grain losses...

Managing invertebrate pests in new farming systems.. There is a continuing need for species-specific research into the ecology of species for which there are currently no effective controls, such as European earwig... The question of pesticide effects is currently being addressed through the GRDC-funded project "Developing and promoting IPM in Australian grains" which is comparing three pest management approaches: (i) "nil" insecticide input (control), (ii) conventional "high" insecticide input, and an alternative "low" insecticide input approach...
