What it takes to spray rice in California
Flooded paddies are impassable to ground rigs, so drones are a natural fit; higher carrier volumes are common for coverage.
- Carrier volume: 3–5 GPA — higher volumes cost more per acre (more refills, fewer acres/hour).
- Typical passes: 1–2 (fungicide/herbicide over flooded paddies).
- Grown in California: 263,922 harvestedacres (USDA Census of Agriculture 2022) — so there’s real, sprayable rice acreage for operators here.
How big is a typical rice field in California?
The average California rice operation works about 364 acres of rice (USDA Census of Agriculture 2022, 725 operations) — so at these rates a field that size runs about $5,096–$8,008 per application. That’s an average across whole operations; a single field is usually smaller. Rice field sizes & cost in California →
Sources & confidence
California estimate · medium confidence · data as of 2024 — Highest of the contiguous 48. Row-crop band anchored to California rice drone work ($14-22/ac, agdronedirectory). Specialty band from in-state grape ($18-30) and orchard ($20-35) operator quotes. costIndex 1.45 sits just inside the brief's expected 1.5-1.65 window's lower edge, blending the directory's explicit 1.4x row-crop multiplier with the heavier specialty premium driven by CDPR restricted-material NOI permitting, school/waterway buffer zones, SprayDays notification, high labor, and small high-value blocks (8-12 passes/season). Confidence medium (operator rate cards + directory multiplier, no current CA extension survey isolating aerial/drone).
