WSU extension Q&A: April 17, 2010

Q. How do I know what is a good grape variety from a nursery?

A. First make sure that any variety you buy is certified disease-free.

There are basically three categories of grapes: American, European and hybrids. American grapes, like concord, tend to be disease- and insect-resistant so you are almost guaranteed success and ease of care, unlike European wine varieties. Many of the hybrids have American characteristics, so try to choose one that is resistant and cold hardy.

Q. We don't live in the country and we don't have animals. Can I still get my kids in a 4-H group? What kind of projects would they do?

A. Contrary to the many stereotypes about 4-H, it is not just for farm kids with animals. 4-H has a major presence in the Seattle area through our adventure education programs, science and technology programs, nutrition information programs, arts, theatre, microwave magic cooking and much. If you have an interest, 4-H has a way for you to pursue it.

Q. I've heard that WSU is recommending garden insecticide products containing Spinosad for controlling codling moth in backyard apple trees and for control of cherry fruit fly. I want to try this on my trees, but can't find any products that contain Spinosad.

A. A number of Spinosad products are labeled for home garden use, but may not be readily available, especially in large local chain stores. I would recommend asking for them at specialty garden stores or nurseries that carry a full line of pest-control products. Look for Bonide Captain-Jack's Deadbug Brew, Bull's-eye Bioinsecticide, Conserve Turf & Ornamental Insect Control, Green Light Lawn & Garden Spray with Spinosad, Monterey Garden Insect Spray or Natural Guard Spinosad Landscape & Garden Insecticide. There also are some are slug and insect bait products that contain Spinosad, but these aren't for use on fruit trees.
