Efficient nitrogen fertilization management for all irrigated crops is gaining much attention as the Irrigated Lands Programs in the Central Valley and Central Coast begin efforts to minimize nitrate movement past the root zone of fruits, nuts and vegetables. The first in a series of seven educational videos on nitrogen fertilizer management is now available online. The video series is …
The USDA National Agricultural Statistics Service has forecasted contracted production for California processing tomatoes at 12.9 million tons for 2023, averaging 50.8 tons per acre. The current production forecast is 23% above last year’s contracted production of 10.5 million tons, and 2% above the May forecast. The projected harvested acreage of tomatoes grown under contract is 254,000 acres, up 13% from 2022. …
USDA’s Animal and Plant Health Inspection Service (APHIS) is issuing a Stakeholder Registry announcement extending the public comment on two pathway risk assessments and three potential regulatory policy options for Tomato brown rugose fruit virus (ToBRFV) in fresh tomato and pepper fruit for consumption and plant propagative material (including seeds). The public will have an extra 30 days to provide comments to the …
USDA’s Animal and Plant Health Inspection Service (APHIS) is issuing a Stakeholder Registry announcement to solicit public comment on two pathway risk assessments and three potential regulatory policy options for Tomato brown rugose fruit virus (ToBRFV) in fresh tomato and pepper fruit for consumption and plant propagative material (including seeds). To safeguard U.S. agriculture against the introduction of the virus into the …
In recent years, there has been an increase in crown rot/vine decline problems in processing tomatoes. Many tolerant, as well as several susceptible tomato cultivars, have been identified from previous efforts funded by CTRI. The number of fields in the Sacramento Valley with confirmed Fusarium falciforme vine decline has been increasing each year. In 2022, eight new tomato fields were diagnosed in Sutter …
Farmers know that heat stress and drought are hard on plants. But what, exactly, is happening to the plants under these conditions, and what can we do about it? These questions are becoming ever more urgent as we move toward a future with more carbon dioxide (CO2) in the air, more heat, and more erratic weather. At ARS, researchers set …
Amber Vinchesi-Vahl, UCCE — The Pest Management Strategic Plan for Processing Tomatoes in California (see attachment) was published in May 2021 and encompasses a wealth of information on pest issues and farming practices for processing tomatoes in California. Myself, Cooperative Extension Specialist Cassandra Swett, and UC IPM collaborated on creating this document directly from stakeholder input and funding from the Western IPM Center. …
As of January, California’s tomato processors reported they have, or will have, contracts for 12.4 million tons in 2023, which is an increase of 18% compared to 10.5 million contracted tons forecast in the August 2022 California Processing Tomato Report. Processors estimate that the contracted production for 2023 will come from 248,000 acres, generating an average yield of 50.0 tons per acre. …
A team of researchers has assembled a reference genome for Solanum lycopersicoides, a wild relative of the cultivated tomato, and developed web-based tools to help plant researchers and breeders improve the crop. Solanum lycopersicoides (S. lycopersicoides) harbors a gene making the plant resistant to a particular strain of bacterial speck disease. The gene could be introduced into cultivated tomatoes to protect …
