S11 E1 - Broomrape (Orobanche)

Season 11 opens with Dr. Brad Hanson of UC Davis, who joins Joe and Alyssa to unravel the resurgence of broomrape, a challenging parasitic weed threatening California's tomato processing industry. Brad explains how broomrape's underground lifecycle, tiny long-lived seeds, and strict reliance on host plants make it difficult to detect and manage. The episode covers the difference between broomrape species appearing in North America, why processing tomatoes are especially vulnerable, and how broomrape spreads through equipment and soil movement. Here are some sources Dr. Hanson shared for the listeners: UC broomrape page (in progress) https://broomrape.sf.ucdavis.edu/ California Tomato Research Institute's broomrape resource page (mostly UC extension info) https://tomatonet.org/grower-resources/broomrape-resources/ California Department of Food and Agriculture broomrape program page https://www.cdfa.ca.gov/plant/ipc/broomrape/ This is a video article that the UCD college of ag put together a couple years ago https://caes.ucdavis.edu/news/parasitic-weeds-threaten-tomato-plants-california-farms

Barnum.Some laws teach the need for prudence (“Law 1: Never Outshine the Master”), others teach the value of confidence (“Law 28: Enter Action with Boldness”), and many recommend absolute self-preservation (“Law 15: Crush Your Enemy Totally”).

His girth gave rise to a famous anecdote. During World War I a lady in London asked why he was not 'out at the Front'; he replied, 'If you go round to the side, you will see that I am.' On another occasion he remarked to his friend George Bernard Shaw: "To look at you, anyone would think a famine had struck England". Shaw retorted, "To look at you, anyone would think you have caused it". P. G. Wodehouse once described a very loud crash as "a sound like Chesterton falling onto a sheet of tin."( Summary from Wikipedia )
