Three products get minor-use registration for this year Three new products have received minor-use registration for


berry crops in 2014: Exirel (cyantraniliprole) is a Group 28 insecticide that received a registration in late 2013 in blueberries and other bush berries for the control of aphids, blueberry midge, several species of caterpillars and spotted wing Drosophila. In March 2014, black vine and clay coloured weevils were added to the label.As with most insecticides, to protect bees, do not apply during bloom. The label warns against tank mixes and sequential applications with strobilurin (Pristine, Cabrio), copper and captan fungicides because of crop injury concerns. The pre-harvest interval is three days. Two Group 2 herbicides received registration.


“In spite of all this work and process, we are still having major challenges where we have gaps or have products that are not as effective as our competition. American growers have access to way more tools,” he adds. Access to a variety of effective tools also helps prevent pathogens and pests from developing resistance to the tools that are already in place.


“If we don’t get more attacking modes for the disease, resistance builds up,” Krause explains. “The first stage was getting some tools on the list. Now we’re on second stage for a lot of things, and need to get another one or two products registered so we don’t get resistance and lose the effectiveness of what we have.” For B.C. berry growers, the inability to obtain tools that are used for pest management in the United States is particularly poignant.


“B.C. is different in that we are farming right at Zero Avenue, and our competitors across the ditch (in the U.S.) have tools we don’t have,” says Krause. “We are selling in the same marketplace, so how do we compete? We’re really trying to make sure that they understand that in Ottawa.” In addition to the US, the industry and PMC are also working on harmonizing standards with Europe and Asia. With increasing berry exports, it is important to be aware of residue tolerances for different compounds and ensure that the chemistry is acceptable in priority markets.


“Being able to get a pesticide registered for use is great, but if it’s not recognized with other countries it doesn’t help us,” says Krause. “There’s a lot of work that has to happen around just getting something registered.” “Overall I would like to see things happen faster, but I have gone from being a skeptic of the process in the beginning, to a supporter of the process.

PrismSG (rimsulfuron) is a post-emergence herbicide registered on blueberries for the control of red root pigweed, barnyard grass and some other broadleaf and grassy weeds. It should be only be applied to healthy, vigorous crops established at least one year. Sandea (halosulfuron) has both pre- and post-emergence activity and is registered on blueberries and caneberries, raspberries/ blackberries) for control of a wide range of broadleaf weeds.Apply to crops established at least one year. For Elliot variety, crop should be at least four years in the field before treatment. For more information see the B.C. Berry Production Guide and PMRA websites.
