Description:

Broomrape is a noxious parasitic weed that recently re-emerged in processing tomato fields in California, with the outbreak centered in the southern Sacramento Valley. Several broomrape species are highly regulated at the state and federal level because of their risk to important crops and are not currently well established in the US.  This parasite attaches to the roots of tomato and other host crops and does most of its damage to the crop before it emerges from the soil.  Once it emerges, it can be difficult to detect because of its small size but can quickly produce thousands of tiny seeds which are easily spread in soil.  

Who should attend?

  • Organic farmers:  Broomrape can affect tomatoes and several other broadleaf crops and seed are easily spread on equipment
  • Pest control advisors
  • Custom operators working in the central valley

This webinar will cover:

  • Broomrape ID - Branched and Egyptian broomrape
  • Broomrape biology
  • Broomrape field scouting and what to do if you find broomrape
  • Organic management tools, including equipment sanitation - organic methods are limited
  • Current best management practices for managing broomrape and reducing the risk of introduction into new fields, including conventional control methods

Speaker bio:

Brad Hanson is a Cooperative Extension Weed Specialist in the Plant Sciences Department at UC Davis.  His statewide research and extension program focuses on chemical and non-chemical weed management in tree and vine crops, herbicide-resistant weeds, and management of branched broomrape in processing tomato.
