Ningxia scouting party

The instructor and students from the Ningxia University wine program in China scouted the vineyards this morning for pests, diseases and other problems. We found many different things including sour rot with spotted wing drosophila, Grapevine Vein Clearing Virus, phylloxera, Japanese beetle, downy mildew as well as two other rots that we tentatively think are ripe rot and bitter rot.

The instructor and students identify the various bunch rots they collected.

Kidfest held today at Mountain Grove fairgrounds

The Missouri State Fruit Experiment Station participated in Kidfest again this year. Great interest in the bee hive display put together by John Avery. Susanne Howard handled the bees while Micheal Kovens, Pragya Adhikari, Leann Hubbert and myself helped the kids with the bean bag toss and rewarded them with apple stickers and activity pages.

There was a bit of rain in at the beginning of the event, but this led into a beautiful day!
