I just got an e-mail from UC ANR (Agriculture & Natural Resources) about the two revised (weed science) publications. They're free!

Plantain weeds Pest Notes updated - Feb 26, 2020
Plantains are common weeds in lawns, athletic fields, ornamental plantings, roadsides, and pastures. Two species, broadleaf and buckhorn plantains (Plantago major and P. lanceolate) are commonly found throughout California year-round.
Plantains grow well in irrigated turf and lawns that are frequently mowed since they grow low to the ground. They can be a major pest for turfgrass managers since they grow in dense...

At the recent CWSS meeting in Monterey there were a number of presentations on the impact of precision and robotic technology in weed management. The weed school consisted of presentations that detailed technology for large scale monitoring of agricultural fields as well as small autonomous weeding robots that differentiate crops from weeds and selectively kill the weeds in the same pass. Both scales of technology have their place. Large-scale cropping systems such as wheat in the great plains are grown on very large farms where efficiency and ability to monitor large areas at low-cost is essential. California vegetable farms tend to be much smaller and more intensive with workers in every field most every day for harvesting,...
Leeks were grown on 589 acres in Monterey County in 2018 and were worth $10.8 million. Depending on the planting date, they can be in the field for 120 or more days, particularly if they are over wintered. They can be grown from seed, but are commonly transplanted to overcome slow initial plant growth. Weed control in leeks is quite challenging because, like onions, they never form a dense crop canopy that can effectively compete with weeds. In addition, given the long crop cycle, a leek planting may experience flushes of both cool and warm season weeds.
Weed control options in organic leeks consist of 1) locating leek planting on blocks with low weed pressure (e.g. blocks with careful weed control in prior crop rotations), 2)...
