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%...

Along scenic corridors, county roads and state highways of the foothills of the Sierra Nevada mountain range, weeds—especially yellow starthistle and Italian thistle—are creating solid stands of invasion that defy control.
The California Department of Transportation (CalTrans) manages over 15,000 miles of roadway and over 230,000 acres of right of way. Along state highways CalTrans manages a narrow easement strip on either side of the roadway for vegetation control. According to CalTrans, vegetation management is performed to: 1. reduce fire risk, 2. improve line of sight and 3. increase visibility; 4. protect road edges from weed damage. Noxious weed control is the last priority listed.
However,...

Despite the fact that I am currently working in orchards and vineyards, I receive lots of requests to discuss Palmer amaranth (Amaranthus palmeri S. Wats.), a weed that I spent almost six years studying. It's the scourge of the Southeastern United States - and a weed that I think everyone should be (or at least become) very conscious of.
Considering that Palmer amaranth is starting to rear an ugly head in California cotton and perennial cropping systems, I thought that I might start a series of blogs revisiting some of the research that I was a partner to in Georgia.
First things first, though...what is Palmer amaranth?
Palmer amaranth, also commonly known as careless-weed (because it can get away...
