Reducing the risk of snail contamination this harvest
Plain text source:
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...
