Codling Moth Control

Codling Moth Control

Codling Moth Control. I'm Greg Martin with today's Fruit Grower Report.

Dr. Jay Brunner, WSU Entomologist recently spent some time talking to the tree fruit industry about work that is being done on aerosol pheromone dispensers to aid in codling moth control.

BRUNNER: In the last decade pheromones for codling moth control has continued to increase and out best estimates on bearing acres is about 90% of the bearing acres are treated with some kind of a pheromone technology for codling moth. And research has led to some new products and technologies and it's certainly helped stabilize the cost of pheromones relative certainly to the newer pesticides that have been introduced.

Brunner talks about a couple of emitters that are available for the industry.

BRUNNER: Both are pretty much the same in terms that they release a mist or a puff of pheromone every 15 minutes for 12 hours is the standard protocol. And they are recommended at one unit per acre versus two or three hundred per acre for the hand applied passive dispensers.

And he says they will last an entire season.

BRUNNER: They require a border treatment. You can imagine one emitter per acre, there's going to be some gaps especially along borders. These plumes emitting from these dispensers are very large and grow as they are carried down wind but you do have these vulnerability along the borders where you need to treat with hand applied dispensers.

More on Monday.
