UC Weed Science (weed control, management, ecology, and minutia)

When wildfires burn in California, people often call them forest fires or brushfires, but the odds are high that an invasive weed is an unrecognized fuels component, says a UC Agriculture and Natural Resources scientist.

Weed control in lettuce and other crops is a key issue this time of year. Purslane is particularly problematic and is adapted to warm conditions and can grow very rapidly especially during July and August. At times growers and PCAs are disappointed with the efficacy of Kerb on this weed.

Welcome to summer! Or at least I think it's summer since southern California is having a very strong June Gloom period that started before June and has touched July. You folks up north have had some pretty hot days though.
