[TriplePundit 15 May 2013 by Tina Casey] -- Chicago’s Department of Aviation announced that O’Hare International Airport is getting its own herd of goats to help manage vegetation, so even though the pilot project hasn’t even gotten off the ground yet it’s already a whopping success. That’s because, although the airport does expect to realize some concrete bottom line benefits from...

Here's an article from the UCCE San Joaquin County Field Notes newsletter (May 2013.)
Medusahead has been invading our rangelands for years. The Natural Resource Conservation Service (NRCS) has photo documentation from the early 1980’s with large stands of medusahead on the east side of the county. Medusahead can also be found in the Livermore area but until this spring I have never seen it on San Joaquin County’s west side. It is a very invasive grass that can potentially reduce grazing capacity by at least 50%. Early detection and control can help eradicate it on a ranch. Here I summarize the research projects that my...

Cilantro was produced on 5,543 acres in Monterey and Ventura Counties in 2011. The production of cilantro has shifted to high density 80-inch wide beds and a large proportion is now mechanically harvested. Hand weeding high density beds is very expensive and reduces the economic viability of this crop. As a result, there is a need for excellent weed control. Two broadleaf herbicides were registered on cilantro: Prefar and Caparol. Prefar was registered for a number of years and provides good control of a number of key weeds in cilantro such as purslane, lambsquarter and pigweed. Caparol was registered in 2012 and provides good weed control of a wider spectrum of weeds including the nightshades, shepherd’s purse, sow thistle,...

Weed control in onions can be challenging. Onions have various challenges that make weed control difficult. They grow slowly early in the crop cycle and never achieve a good competitive crop canopy to suppress weeds. Also, given the high density plantings, it is not possible to effectively cultivate the beds. In addition, given the close spacing between plants, it is difficult to hoe out weeds without risking damage to the onion stand. In conventional onion production there are a number of materials that can provide excellent weed control (see Figure 1). The timing of application of the materials can be tricky because some weeds may grow quickly and be difficult to control by the time the onions reach the 2nd...

Here's an article from the Sweetpotato Tips newsletter on hotbed cost production. Click here for a direct link to the January 2013 edition.
PRODUCTION NOTES—Hotbeds
Hotbeds begin soon. If you did not use methyl bromide in the last year, improve weed management by using Devrinol herbicide at a rate of 12 oz per 1000 ft of bed in 5-6 gallons of water (sprayer calibrated at 30 gpa). Apply before the first irrigation and prior to the emergence of weeds. Incorporate with a brief irrigation—about 10 minutes will do. This gives about 80-90%...
