Decon Aquatic Invaders!
How can boaters, anglers, and anyone else who works or plays in wet places help stop aquatic invasive species from conquering new territory? Decon (decontamination) is critical. Invaders can hide in mud on the tread of your boots, cling to the hem of your pants, lurk in damp reels and creels, hang out in bait wells and bilges, yatta yatta! They’re experts at surviving, so you can carry them to the next spot. What’s the first step in decon? Just take a look! In other words,...Off to See the Butterflies

Dry bean meeting shares crop management and marketing strategies.
Dry beans are an important rotational crop in the Southern San Joaquin Valley. They are not a high value crop, so effective growing and marketing practices are a priority. The dry bean meeting held at Kearney on August 27, 2013 attracted about 30 attendees. It focused on many aspects of new crop management and marketing strategies to improve the return per acre of dry beans.
There were four field presentations. Larry Schwankl, UC Cooperative Extension irrigation specialist at Kearney Agricultural Research and Extension Center, and Carol Frate, UC Cooperative Extension advisor in Tulare County, alfalfa, dry beans, corn and plant pathology, discussed a subsurface drip irrigation trial for blackeye production. Carol Frate discussed the evaluation of insecticides for lygus bug management. Phil Roberts, chair and professor in the Department of Nematology at UC Riverside, nematode host-parasite relations, genetics and pest management in field and vegetable crops, discussed screening bean varieties and breeding lines for root knot nematode resistance. Phil Roberts and Bao Lam Huynh discussed developing new varieties of beans for insect and disease resistance.
Indoor sessions included PowerPoint presentations and related discussions. Gary Luckett, manager of the Cal-Bean & Grain Warehouse, provided an update on the blackeye market. Bao Lam Huynh discussed using marker-based techniques for developing new blackeye varieties. Kurt Hembree, UC Cooperative Extension advisor in Fresno County, weed management strategies in crop and non-crop settings, discussed past, present and future methods of weed control in dry beans.
The meeting provided:
- PCA hours: 1.5 hours of “other”
- CCA hours: 1.5 hours of IPM; 0.5 hours of crop management
