This is the first time since I moved to California that I've seen leafhoppers actually injuring rice. Leaf tips turned yellow, and from the road it looks like salt injury, but once you get in the field you can see leafhopper nymphs and adults jumping and flying around.

I've been getting calls about sedge surviving propanil applications. Last year, research conducted by Albert Fischer showed that there are populations of smallflower umbrellasedge that are truly resistant to propanil (read the article here).

A few weeks ago I was on the phone with a grower worried that he had put too much nitrogen on his rice for the cool year we were having. Then, the weather turned and got really hot.

The 2013 Rice Production Workshop will be held on July 25 at the Lundberg Family Farms Multi-Purpose Room, 5311 Midway, Richvale, CA.

Its that time of year again when hot weather fuels the creation of ozone, or smog. Some pesticides emit volatile organic compounds (VOCs) that contribute to ozone formation. Using pesticides that release VOCs may be restricted in certain California locations between May 1 and October 31.
