As the 2024 tomato planting season in California nears completion, growers have successfully managed to stay on schedule despite minor weather-related interruptions. This season, growers have been fortunate not to face severe weather conditions, allowing them to focus on other critical issues.
One significant challenge this year is the new rule banning the application of neonicotinoids on flowering plants, which affects processing tomatoes. Traditionally, many growers in southern California used insecticides in greenhouses before transplanting to protect young plants from sugar beet leafhoppers, which spread the damaging curly top virus. In response to the potential threat, Kern County declared a local emergency in April, allowing the use of neonicotinoid pesticides to protect 8,000 to 10,000 acres of processing tomatoes. Northern counties have also declared or are in the process of declaring emergencies, aided by good annual grass growth that minimizes leafhopper host plants.
The emergency declarations and use of neonicotinoids raised concerns among customers about supply reliability. However, these measures are precautionary to ensure crop protection.
Another pressing issue for California growers is the reemergence of the invasive branched broomrape weed, a parasitic plant that attaches to plant roots and spreads rapidly. In the 1950s, a severe infestation in the Sacramento Valley was managed through industry-led efforts and fumigation. With the weed's reappearance, ongoing research aims to develop treatment and eradication strategies. Agriculture Secretary Karen Ross has formed a committee to create a strategic plan to combat broomrape in California.
Morning Star, a leading tomato processor, is actively involved in preventing and controlling these invasive species. The company's strategy includes maintaining a geographically diverse sourcing region to mitigate the impact of localized issues on the overall supply.
While tomato farming in California comes with its challenges, the proactive measures and collaboration among growers and industry partners ensure a reliable tomato supply to meet customer demand. The resilience and adaptability of the industry highlight its commitment to overcoming obstacles and securing the future of tomato production in California.
