Anti-genetically modified crops campaigners are looking to ensure there is no contamination of canola and other brassica species around the Lubeck receival site in Victoria's Wimmera, which will be handling GM canola this season.
GM Cropwatch volunteer Jessica Harrison, who is involved with the Network of Concerned Farmers (NCF) said she hoped farmers would get hold of the simple and cheap testing kits if they had concerns about unwanted GM material.
The kits can be used on the spot to test for the presence of GM.
"Test kits allow farmers to check suspect canola plants which may end up blown into their paddocks from transports in the area," she said.
Ms Harrison came across to the Wimmera on a tour from Gippsland and said she had been in contact with a number of growers regarding GM issues.
Speaking on a windy day at Lubeck, Ms Harrison said the weather highlighted the need to monitor possible contamination of roadsides and nearby paddocks.
"Canola seed would be able travel some distance on the breeze today," she said.
Along with that, she claimed there was an issue with seed spilling from trucks and headers.
"Canola seed is notorious for spilling from transport vehicles and can lay dormant for 16 years prior to germinating, according to the Office of the Gene Technology Regulator," she said.
The major focus of the trip was the monitoring of roadsides and railway lines.
