Growing Produce has published its rundown of the most popular crop protection products California farmers used in 2025, a ranking that arrives as input budgets tighten across the state's specialty-crop sector.

The publication lists the top products by grower usage, drawing on its annual review of what California producers actually sprayed, spread and applied during the 2025 season. Crop protection spending routinely ranks among the largest variable costs for the state's fruit, nut, vegetable and vineyard operations, so shifts in product rankings feed directly into per-acre cost structures and margins.

What does the ranking cover?

• The most widely used crop protection products among California farmers in 2025
• Products spanning the chemical and biological categories growers rely on across the state's dominant specialty crops
• Usage patterns tracked through the 2025 production year

California remains the defining market for U.S. specialty-crop pest control. The state's regulatory environment — tighter than federal rules in several cases — shapes which chemistries remain available, and product loss or restriction there tends to ripple into formulation choices and pricing for growers in other regions.

For input suppliers, the ranking signals where demand concentrated in 2025. For growers and their advisors, it offers a benchmark: whether the materials they budgeted for matched what the broader farm community leaned on through the season.

The full product-by-product breakdown, including specific materials and their standings, is available in the Growing Produce report.

Growers and ag retailers tracking the 2026 season will be watching whether these usage patterns hold as registration reviews, active-ingredient restrictions and input price movements continue to reshape product availability.
