Can Area Wide Management Eradicate Vine Mealybug?
If you are dealing with vine mealybug in your vineyard, you are not alone. Kent Daane, Cooperative Extension Specialist at the University of California Berkley studies different types of mealybug populations across the globe. Kent covers organic and conventional strategies, ways to increase the presence of generalist and specialist natural predators, and the importance of establishing refugia for beneficials. His latest work focuses on area-wide management tactics. Looking to the European Grapevine Moth eradication program as an example, Kent sees an opportunity to decrease vine mealybug populations through neighborhood driven monitoring, trapping, coordinated sprays, and mating disruption.

He is a Cooperative Extension Specialist with the University of California, Berkeley, and he works primarily out of the Kearney Agricultural Research and Extension Center. And today we're going to talk about a number of topics. Thanks for being on the podcast, Kent. [00:00:17] Kent Daane: Craig, thanks. I'm happy to be here. [00:00:20] Craig Macmillan: Let's dive in on one pest that everybody's interested in, continuing to be interested in, and you may have some new insights or newer insights on this. Let's start with mealybug management. Kind of what's the state of the art in that topic right now? [00:00:33] Kent Daane: Yeah, that's been the number one question I've been getting for many, many years now. It is an invasive pest. We know it came in, probably being brought in by a grower down in Coachella Valley. It has since spread into the San Joaquin Valley, Central Coast area where you are, Napa Sonoma, and it's been found now in Oregon. Just like Napa, Oregon has attempted an eradication program. And probably just like Napa, most likely it's not going to work. It's a very, very difficult insect to kill 100%. I mean, I can come up with all kinds of different programs, soft programs, hard programs, expensive programs, inexpensive programs, where I can suppress that insect pest. It's very difficult to remove it from a vineyard. And that becomes important when you think about the kinds of damage we're worried about in Central Coast wine grapes. Pretty much anywhere where they're looking at grape quality. But especially in the cooler re
