Fidelibus, who is based at the Kearney Agricultural Research and Extension Center, installed the covers in September on a Redglobe vineyard near Easton. Some farmers choose to grow late season table grapes – such as Autumn King, Crimson Seedless and Redglobe – to market in the fall when prices are typically highest. However, they run a greater risk of being rained on. Exposure to moisture within six weeks of harvest can cause rots and molds to render the grapes worthless.
Many growers with late-season table grapes cover their vines with sheets of plastic film to protect them from rain. Growers may choose between a relatively transparent green film, or a more opaque white film, but data distinguishing the differences the two films might have on vine physiology or fruit quality at picking, or after storage, are not available. Buying, installing and removing the plastic is very expensive, so Fidelibus is working to provide growers with objective information about the effects of the different films. Growers can track the progress of the trial in real time by following Fidelibus’ Twitter feed, http://twitter.com/grapetweets.
“In some places we found pools of water on the plastic covers,” Fidelibus said. “In fact, the weight of the water displaced the covers, exposing the vines in some places. A few pools apparently grew until reaching a vent hole, releasing a water stream powerful enough to wash soil from roots.”
After the storm, the soil under the covered vines remained dry, but wind and sun quickly dried the grape clusters and soil around uncovered vines.
Data loggers in the grapevine canopies are collecting temperature and humidity readings – measures that Fidelibus will use to help describe the effect of the different covers on the environment within the grapevine canopies. He also installed atmometers, special instruments that help determine the canopy’s “evaporative potential.” Research has already shown that the greater the evaporative potential, the lower the incidence of bunch rot.
Bentley was named the UC Cooperative Extension entomology advisor for Kern County in 1977. In 1994, he was promoted to his position with the IPM program and relocated to the Kearney Agricultural Research and Extension Center in Parlier. Bentley was nominated for the award, a statewide honor, by his colleague, UC IPM nematologist Peter Goodell.
Goodell said Bentley has had only two driving forces in his career: create practical yet high quality entomological knowledge based on science and direct that knowledge to make a difference in the lives of the people he serves.
"Mr. Bentley's career represents the best UCCE's faculty has to offer: unselfish service, loyalty to his peers and clientele, intellectual honesty, dedication to the mission of UCCE and a genuine love for his work," Goodell wrote.
