Field bindweed (Convolvulsus arvensis) is considered by many tomato growers to be the most problematic of all weeds in California production areas. Indeed, field bindweed and the closely related morningglory weeds were ranked the 8th most troublesome weeds in North America in a recent survey by the Weed Science Society of America (Van Wychen, 2019). The rapid adoption of drip irrigation and the economic necessity of maintaining the beds and replanting with only minimal tillage for multiple seasons in processing tomatoes has created a system where field bindweed has become more prevalent. Field bindweed is extremely difficult to control because it propagates from seed and vegetatively...

In a recent blog post, Dr. Clyde Elmore discussed weed species changes in urban environments in response to the ongoing drought. One weed that can thrive under dry conditions is field bindweed, a significant weedy pest for homeowners, land managers, and farmers, alike.
NOMENCLATURE:
Field bindweed was first named by Linnaeus in 1753; its Latin binomial (Convolvulus arvensis) is derived from convolvere ("to roll together") and arvense ("in the field"). Which is pretty appropriate, if you ask me.

Weed control in cool-season vegetables can be quite challenging. However, there are a number of practices that provide growers with certain advantages:
- Short-season crops such as lettuce and spinach that allow for rapid turnover of the crops (e.g. 30 to 65 days), frequent cultivation (lettuce) and/or complete hand removal of weeds prior to mechanical harvest (clipped spinach and baby lettuce)
- High value of the crops allows for the use of intensive hand-removal of weeds, often prior to seed set
- Small production blocks that allow for careful observation and intensive management
All of these strategies have basically made some of the most troublesome weeds such as field bindweed and yellow...

Plant growth and development and herbicide efficacy, part 1
In the 1920's and 30's field bindweed (Convovulus arvensis) was a major weed in the western US; so much so that coordinated research was undertaken by the most prestigious Agricultural Universities from California to Oklahoma to figure out what to do. And this was before the advent of herbicides, so scientists and farmers had to rely on other methods, especially cultivation. After much work, it was discovered that the pernicious bindweed could be eradicated from a field by regular cultivation for just two seasons. They used duck-foot cultivators; a collection of several flat triangular blades that overlapped and ran horizontally about 2-4 inches below the...
