Windrow burning as a tool for snail control - Barley locations

To determine the impact of stubble burning on snail populations in a canola paddock

Key messages

Windrow burning can reduce small pointed snail populations by over 90%. If there are weeds or fallen stubble that are not burnt then snails can still be present in the paddock.

Soil amelioration

The paddocks were harvested in December 2015 and a  hay rake was used to rake all of the barley chaff into windrows in January 2016.

Swaths were on the ground and fallen stubble and weeds were present in the inter-rows.

Pre-burn assessments were done 11th March 2016, paddocks were burnt 19 March 2016 and post-burn counts were done 21st March 2016.

Every 10 metres for 100 metres, the number of snails in the barley windrow in a 0.1 metre square quadrat were counted. The snails were all collected and spray painted with bitumen paint. The snails were then placed back to where they were found and the windrow replaced. For every count in the windrow, the adjacent inter-row (2 metres from the windrow) was also counted. All the snails in a 0.1 metre square quadrat were counted, sprayed with bitumen paint and then placed back to where they were found.

After windrow burning, the same locatio
