Warmer Weather and Rain Bring Mosquitoes

What's that wet stuff falling from California skies? Could it be the "R" word, rain?  Or what Wikipedia calls "liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated—that is, become heavy...

May showers

A wise man once said that God made weather so farmers would have something to complain about. Or maybe he was just a wise-acre.

One very wet spring a few years ago I was talking with another wise man, the late UC plant pathologist Joe Ogawa. I told him that the fruit trees must be enjoying the rainy weather. Joe's response: "Oh, the trees are probably enjoying it—but the fungi are so excited they're jumping up and down!"

I was working that spring with Joe and his colleague Harley English on their book, Diseases of Temperate Zone Tree Fruit and Nut Crops. Sure enough, our meetings were often interrupted by phone calls from farm advisors, port inspectors, or scientists from USDA or the California Department of Food and Agriculture wanting advice about some piece of fruit they'd found covered with soggy bruises or a fuzz that was not its own. Joe knew his stuff and was eager to help. His idea of a really interesting pear or plum was the sort of thing that would send most of us out of the produce section and over to the canned or frozen fruit aisle in a hurry.

But his point about the rain that day was that it does a lot more than fill our reservoirs and nourish our plants. A late rain can also split cherries on the tree, spoil other fruit unless it gets immediate cultural or chemical treatment, and keep fields muddy enough to keep tractors out and delay planting for tomatoes and other crops. Growers rely on UC people like Joe Ogawa to help them find ways to address those problems without driving their costs (and yours) through the roof.

As a food shopper there's not a whole lot you can do about it—just enjoy the weather while you can, enjoy the food you do get, and hope for better growing conditions and prices next year. Sounds like farmers aren't the only ones complaining after all!
