Joe DiTomaso, John “JR” Roncoroni, and I evaluated a purple starthistle trial in Napa County last month. Several selective herbicides, two times of application, etc etc… one of the replications got flooded out, so I can vouch that Very High Rates of H2O are capable of controlling this weed… but the point of this post is a neat idea that JR had during the evaluation.
With digital cameras, it's become more or less routine to photograph every plot during evaluation. Sometimes it really helps with interpreting the data if you can take another look at the plots after running the statistics. But many of our plots are a long drive away, and in the meantime the sun has turned all the vegetation into...

Last week I sat in on the Weed Science School at held at UC Davis. This event is held every two years (alternating with the Aquatic Weed School) and is intended as a refresher or high-level introduction to weed science for professionals in the field. I always enjoy sitting in on as many of the lectures as I can because I always learn something (either completely new or previously forgotten!) from my colleagues.
Kurt Hembree (UCCE Weed Science Farm Advisor) led a breakout discussion and demonstration session on the last day of the short course where we talked about the...

This was again an exceptional year with rainfall above normal and extended into the spring. It was very nice to see some areas of green grass still in late May as we finished up our spring production clipping. Both the west side and east side rangelands were well above the normal forage production reported in the soil surveys. The west side ranged from 120% to 170% of normal with one site almost 300% of normal. This equals roughly 2,000 lbs/acre up to almost 7,000 lbs/acre for the most productive site. The east side was equally as productive with most sites ranging from 110% to 250% of normal, ranging from roughly 1,900 lbs/ acre upwards of over 5,500 lbs/acre.
Unfortunately we also saw...

Water prices are increasing and so are the regulatory pressures on agricultural runoff and sediment losses. How much more efficient can vegetable growers get with their irrigation practices? Drip irrigation as the most efficient method of field irrigation is not new to vegetable growers but the sprinklers are typically used for the first 4-6 weeks for the transplant establishment and either application of herbicides with overhead water or activation of herbicides previously applied by ground methods.
However, there are several vegetable operations that rely solely on drip as an irrigation method from start to finish, even for such water-thirsty...
