One point I always make is that the sooner you control annual weeds, the better. The reduces crop-weed competition, along with a host of other issues caused by weeds (we'll save that for another blog). But the real key to forward-looking weed management is to kill the weed before it produces seeds. Once seeds are produced, they contribute to the seed bank, pretty much ensuring that the weed population will be a continual problem.
But suppose you miss some weeds that are starting to flower but the flowers aren't open yet? I think most growers will just pull or cut the weed and leave it in or near the field.
I want to show you a time-lapse video I took. I cut the flowering stem off of an...

A quick post to share a really interesting website created by the USGS National National Water-Quality Assessment (NAWQA) Program. This site creates pesticide use maps showing geographic distribution of estimated (or actual use in California) of several dozen pesticides on agricultural lands for major crops.

The website introduction states:
The pesticide-use maps provided on this web site show the geographic distribution of estimated use on agricultural land in the conterminous United States for numerous...

There are few new herbicide active ingredients in the pipeline now. In the 1970s and 1980s several new active ingredients were introduced every year. There were lots of jobs in industry and weed science was the place to be. I myself was with ICI/Zeneca from 1983 to 1994 in their R&D group. However, we are now in the middle of the second decade of the 21st century and new herbicide active ingredients might cost $300 million from discovery to launch. Needless to say there are not many new active ingredients in the pipeline. We have a few agricultural chemical companies that are screening for new active ingredients and perhaps the large scale of glyphosate resistant weed problems will stimulate some of the agricultural...
