Authors: Travis M.Bean, Scott Stoddard, Lynn M. Sosnoskie, Adewale Osipitan, Pratap Devkota, Guy B. Kyser and Bradley D. Hanson
Abstract
Weed management in cantaloupe and other melon crops, is important to maximize fruit yield; however, there are few registered herbicides available in California. Several independent herbicide trials were conducted at University of California...

Weed management in landscaped areas can be challenging. Weeds may need to be controlled for public safety, fire reduction, aesthetics, and elimination of harborage for other pests. While many non-chemical options for controlling weeds exist—such as physical removal with tools, steam, flame or steam devices, grazing animals, and others—there are some situations that may require the application of herbicides.
For decades, glyphosate has been a common active ingredient used to control weeds in both agricultural and nonagricultural settings. However, there has been significant public concern about the use of glyphosate and other herbicides due to their potential effect on water quality, public health, and non-target...

In Northern California, Pokeweed (Phytolacca americana L.) has been around for a long time and is typically found in disturbed areas and fallow sites such as: under power lines, wooded areas, fences, pond edges, roadsides, etc. (Figure 1). However, in recent years, organic orchard growers throughout north coast have reported that pokeweed has been invading and contaminating new areas that were not found before.
Pokeweed is a perennial shrub whose shoot tissues die in the winter but exhibits rapid resprout from a large fleshy taproot in the growing season, causing panic among orchard growers. That kind of shrub can grow up to 10 feet tall, and a single plant can produce greater than 7,000 seeds annually. The...

Conventional processing tomato weed management in California often includes pre-plant herbicides (trifluralin and/or s-metolachlor), followed by cultivation, and hand hoeing. Rimsulfuron herbicide can also be used in conventional systems and can be applied either pre or post transplanting. Post-transplant applications of rimsulfuron can selectively remove nightshades if applied when the weeds are very young, no more than 2 true leaves, however, long plant-back restrictions may limit its use. Therefore, the use of hand crews is often needed to remove weeds that emerge in the plant row, where standard cultivation equipment is ineffective.
Automated weeders, or robotic weeders, use cameras and computers to distinguish crops from...
