SUMMARY
The current automated weeding machines use cameras to detect plants, and a computer algorithm to process the image, calculate which plants to keep/remove, and activate a kill mechanism. These machines are capable of cultivating within the seedline and removing weeds that would otherwise be left by traditional cultivation. The machines used in these studies included the Robovator, F Poulsen Engineering Aps, Hvalsø, Denmark and Steketee IC Weeder, the Netherlands. Both of these machines use a split knife that as it...

Spray and pray? Squirt and look? Burn baby burn?
Besides the Beavis and Butthead laughs (Heh. Heh-heh. Heh) that usually come when you tell someone you are a weed scientist, is the expectation that you advocate for the use of herbicides as the sole weed management strategy in any given system. I do evaluate chemical weed control (I won't deny it) and, surely, there are those who like to engage in recreational herbicide applications on the weekends; however, weed science is a very varied discipline with investigators that study weed biology and ecology, weed evolution, and weed suppression using biological, cultural, and physical tools.
I was very happy to see the following image (Figure 1)...

I thought I'd make a quick post today to share links to several recent articles in the trade publication "CAPCA Advisor". This magazine is targeted towards Pest Control Advisors (CAPCA = California Association of Pest Control Advisors) and is published every two months. Most issues of CAPCA Advisor have at least one article written by UC Cooperative Extension pest control researchers.
The magazine has a nice web interface with the last 12 issues of the magazine and here are links to four reports by UC weed science researchers:

Abstract: Reduction in herbicide use in non-agricultural areas is being imposed by a growing number of governments, triggering the development of alternative strategies for weed prevention and control. This study aimed to determine the weed preventive abilities of different paving types, the required treatment frequency of non-chemical weed control scenarios on these pavements and the associated weed species composition. A test parking area, constructed with four concrete paving types, was sown with a mixture of dominant weed species. Six scenarios with repeated use of a single weed control method (brushing with waste removal, hot air, selective application of hot water and three scenarios with flaming) and two...
