Weed & Insect Management / Pathogen Management / Miscellaneous

 

Project: 43  Honey Bees and Pollination Education and Research  
Project Leader:  Shannon Mueller
Objective:  1) Improve farm advisors’ understanding of and experience in beekeeping.  2) Improve access to honey bees for educational efforts in Fresno County.  3)  Have access to colonies for pollination research and evaluation of pesticide toxicity in controlled conditions present at the research and extension center.

Project: 45   Cotton Weed Management
Project Leader:   Steve Wright
Objective:  
The overall objective of this continuing project was to develop cost effective weed management strategies that can be integrated into the California cotton production systems. Several studies were conducted both with grower cooperators and at the research station. Several weed control approaches were evaluated both in conventional and herbicide tolerant systems that included new herbicides and tank mix combinations. The focus was on annual morningglory, field bindweed, and nightshade.

Project: 64 Pre- and Post-Emergent Weed Control in Onions 
Project Leader:  Kurt Hembree
Objective:   The objective is to screen Nortron alone and in combination with other herbicides to determine efficacy and crop safety in seeded onions.

Project: 65   Screening DPX-GH438 (oxadiazolidindinones) herbicide for tolerance to Vegetable Crops, Efficacy and Crop Safety 
Project Leader:    Milton McGiffen
Objective: Screen new potential herbicides for several vegetable crops to identify crop / herbicide combinations that have for registration.

Project: 66   Weed Control in Garbanzo Beans 
Project Leader:   Kurt Hembree 
Objective:   The objective is to screen several herbicides and combinations of herbicides to determine efficacy and crop safety in garbanzos by planting and layby.  

Project: 68   Sugar Beet Weed Control 
Project Leader:   Kurt Hembree
Objective:  
Although sugar beets are not grown on a wide scale in Fresno County (about 15-25,000 acres annually), they are a rotational crop for the area. Both winter and summer weeds compete with sugar beets early (depending on wether they are fall or spring-planted), reducing stand and yield. No herbicide or combination of herbicides currently available controls all the weeds in most cases. Dimethenamid (Outlook) is a relatively old herbicide, but being looked at for new crops (including sugar beets) for efficacy and beet tolerance. Outlook is a soil residual herbicide, which controls tough weed commonly found escaping current control strategies, like yellow nutsedge, watergrass, foxtails, purslane, nightshades, and lambsquarters.

Project: 73   San Joaquin Valley Rural Background Air Quality Research Study 
Project Leader:   Anthony Wexler
Objective:   A field research project was initiated: (1) to operate an air sampling station to conduct ambient particulate sampling at multiple time periods during the year in the western San Joaquin Valley in a rural, agricultural location; and (2) to conduct in situ animal exposure studies related to air particulates in this setting. A mobile air sampling station and animal air particulate exposure facility will be located for multiple 30-day periods as part of a larger, multi-site study to investigate atmospheric components of interest for health effects.

Project: 74   Foliar and Seed Fungicide Treatments and Biocontrol for Sclerotinia White Mold Control in Garbanzo Beans 
Project Leader:  Carol Frate
Objective:
 1)     Evaluate foliar fungicides for control in the area that had garbs last year and the area that had lupins. We want to test Headline, Endura and TopsinM at label rates and with 2 timings.   2)     Evaluate seed treatments in the area that had garbs last year and the area that had lupins.  3)     Treat an area north of these trials, where garbs were planted last year, with Contans. This portion of the trial can then be planted to another crop such as wheat and followed by garbanzos in 2007/2008.  4)Continue taking samples of infected plants for confirmation by Mike Davis, UCD Plant Pathologist, of the species of Sclerotinia. 

Project: 76   Evaluation of Herbicides for Dry Beans Under Reduced Tillage Systems 
Project Leader:   Carol Frate
Objective:  To evaluate crop safety with the above mentioned herbicides and to evaluate weed control with the above mentioned herbicides.

Project: 90   Management of Key Cotton Arthropod Pests with Insecticides and Acaricides  
Project Leader:   Larry Godfrey 
Objective: 
1)     Develop an expanded database on the current efficacy of labeled/recommended insecticide and acaricide products on key insect and mite pests of cotton in the San Joaquin Valley and record the impact of these products on beneficial arthropods with the objective of providing better guidelines on pesticide use.  2)     Evaluate the effectiveness of new candidate insecticide/acaricide products on key San Joaquin Valley cotton pests, the impact of these new compounds on populations of beneficial arthropods, and devise strategies for utilization of these new products.3.) Provide outreach to growers, PCAs, UCCE personnel, and others in the cotton industry through appropriate field days, meetings, and publications.
