2020 Field Walk - Vegetable Crop Research Projects

 

Welcome to the UCCE Stanislaus County Vegetable Page. The purpose of this website is to generate and disseminate resources and tools for vegetable stakeholders in Stanislaus County to strengthen their vegetable production and business.

This site provides:

  1. Progress on our area of ongoing research and extension programs
  2. Descriptive photo galleries from different research and extension activities
  3. Various deliverables from our research and extension programs (newsletters, scientific reports, presentation slides, etc.)
  4. Tools that are built to strengthen stakeholders in decision making and troubleshooting

Stanislaus County Vegetable Crops Production

Vegetable production in Stanislaus County is historically diverse in commodities. According to the 2017 Stanislaus County Crop Report, vegetable crop production experienced significant increases in total harvested acreage (20%) and sales value (15%) compared to 2016, reaching totals of 28,630 acres and $180 million, respectively. Tomatoes (fresh market and processing), melons, and sweet potatoes continue to be the major commodities, constituting nearly 60% total acreage and sales value.

Plans for 2020 

There are two major themes for the UCCE Stanislaus County vegetable crops program in 2020: Sustainable Practices Evaluation and Plant Health. 

Sustainable Practices Evaluation: 

  • Influence of compost application rates on nitrogen management and processing tomato productivity and quality: The goal of the project is to develop a better understanding of how fall-applied compost rates influence nitrogen use efficiency of the following year’s processing tomato. This project is financially supported by the California Tomato Research Institute.  
  • Evaluation of rootstock-scion combination on grafted processing tomato yield and quality: In 2020, the UC ANR tomato grafting team will continue the evaluation of the production of grafted processing tomatoes. Together with Dr. Brenna Aegerter from San Joaquin County, we will implement a trial near Stockton to assess the influence of several rootstocks on yield and quality of different commercial tomato scion cultivars. 
  • Evaluation of Biofertilizer and biofungicide on watermelon yield and fruit quality: In collaboration with the BioWorks, Inc., we will implement research trials to collect the performance data of “Rootshield” biofungicide and biofertilizers on watermelon growth, yield, and fruit quality. 

 

Plant Health: 

  • Performance of Sulfentrazone and Acifluorfen on basil production: The herbicide evaluation trials will continue in 2020 with some treatment modifications. Acifluorfen was added as another testing herbicide. These trials will compare different application rates with grower’s standard practice on crop injury, weed elimination, and basil leaf biomass. 
  • Vegetable Disease & Pest Monitoring and Management: In 2020, I will continue monitoring prevalent vegetable crops diseases and related pests. Crops that are covered are, but not limited to, processing tomato, melon, watermelon, sweet corn, and pepper. Fusarium wilt, fusarium crown, and root rot, beet curly top virus, tomato spotted wilt virus, verticillium wilt, powdery and downy mildew and many others, as well as related pest vectors, are of particular attention.
