The latest restrictions follow suit with New South Wales and Victorian restrictions to add a broad range of product line restrictions, in addition to those already in place for the tomato/potato plant family.
Products affected by the latest extension of restrictions include 18 plant families of species that are considered secondary hosts to the insect, including strawberries, apples, lettuce, broccoli and beans.
Produce will need to be treated with effective insecticide or methyl bromide and inspected before it can head to the restricted states.
Washing produce removes psyllid
"The new restrictions are proving very difficult for a lot of WA growers. These are products that are not considered true hosts, in as much as the psyllid can't complete its full life cycle on those crops," Vegetables WA market development manager Claire McClelland said.
"These are lines that have significant trade over east. We are hearing from some growers [that they are losing] in excess of $250,000 a week on some of their lines."
