Agriculture Minister Ernie Bridge says the Liberal and National Parties' approach to agriculture in Western Australia offers nothing new to people on the land.
"They simply promise things which are already underway, or promise things which are a Federal jurisdiction and cannot be implemented by a State Government," he said.
"Agriculture is one of the most difficult areas for the two parties as they have clear differences on some key issues, but I doubt anyone in the bush will be fooled.
"It is well known that the Liberals and Nationals are at odds on issues such as the future of market authorities and guaranteed wheat prices, and I would expect those divisions to become more apparent as the policy comes under scrutiny."
Mr Bridge said the reliance on Canberra to implement some of their promises, such as new anti-dumping measures and labelling requirements, was a worrying trend.
"As is apparent with much of the State manifesto being put forward by the two parties, their promises tend to collapse without a Federal Liberal Government in power," he said.
"In other areas, I welcome their endorsement of measures already implemented by the present Government. This includes such things as tailoring research and promotion to target specific export markets, encouraging farmers to drought-proof their properties, and supporting community-driven landcare programs."
Mr Bridge said some other aspects of the policy were merely confusing, such as suggesting they would replace the Australian Meat and Livestock Corporation, which was a national body.
"The Premier's `Adding Value' plan launched yesterday is a blueprint for transforming the Western Australian economy, with real benefits for primary producers, and it is disappointing the Liberal and National Parties have such limited vision," he said.
