Canadian farmers reel as China blocks top canola seed market

WINNIPEG, Manitoba (Reuters) -Canadian farmers are reeling from China's decision to impose hefty duties on their canola seed, after the surprise move spooked grain buyers into halting purchases and stoked worries there will be little demand for crop deliveries this autumn. China hit Canadian canola seed imports with preliminary 75.8% duties on Tuesday following an anti-dumping investigation, escalating a year-long trade dispute. Grain buyers reacted by yanking their bids to buy crops in the next few months, said Dale Leftwich, the policy manager for SaskOilseeds.
