George Washington Carver Camp visits the experiment station.

Today, Susanne Howard coordinated a tour for the George Washington Carver Camp high school group with faculty and staff from the Springfield campus. Randy Stout took the group on a hay ride, Dr. Martin Kaps presented information on fruit crops and Randy Kreusuer, Kallie Calus and I helped the group harvest raspberries in the high tunnel. Susanne continued on a campus tour with the group. They had a beautiful day for a visit.

Testing for Drosophila larvae in rasbperries

We had a problem with Spotted Wing Drosophila last year when we caught some in traps and noted damage in our raspberries. Today, I harvested some early berries and put them in a solution of 1 cup sugar in a quart of water. After 1/2 hour, Drosophila larvae floated to the surfact. According the “Biology, Identification and Management of Spotted Wing Drosophila” FSA7079 by Donn T. Johnson and Joseph O’Neill – University of Arkansas – “Legless SWD larvae cannot be distinquished from other Drosophila larvae – with two spiracles on one end and two black mouthparts on the other.”

Cayuga White and Seyval Blanc are going in to veraison.

Vignoles was defruited due to low vine size and will not be included in the phenology from this point until leaf fall.

Soon to harvest onions

Simpsons Family Farm just north of Mountain Grove began their onion harvest today. They have an outdoor test plot of Alyssa Craig onions and we have this variety planted in the high tunnel. Both are about the same level of development, but Simpsons onions are larger! Deb French advised that we pick onions when the tops fall over – which should be happening in the next week or so.
