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.
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.
