Weed Day 2012 comes to UC Davis July 19

The morning field tours include: preharvest burndown treatment comparison in walnuts; Dittrichia, tarweed and yellow starthistle root growth dynamics; weed control and herbicide safety in melons; effect on herbicides on tomatoes under weed free conditions; Zeus–a new herbicide for use in tomato; herbicide drift symptomology on row crops; and field bindweed control in processing tomato.

Afternoon presentation topics will consist of: evaluating mesotrione for weed control in orchards and vineyards; weed risk assessment and third-party certification program for nursery plants; herbicide resistance in Echinochloa: clomazone and quinclorac; predicting in-field late watergrass emergence; Dittrichia biology and control; and control of medusahead with high rates of aminopyralid.

Registration is from 7:30 a.m. to 8 a.m. Cost is $80 if registered by July 6 and $110 for those registering after that date and includes light refreshments, lunch, and handout materials. The cost for students (with a valid student ID) is $35. Class size is limited so early enrollment is always a good idea for this annual event.
