A $2.3 billion farm county

Madera County's 2024 crop and livestock report totaled $2.33 billion, up from $1.86 billion in 2023.

Commodity	2024 value	Acres
Almonds	$702.2 million	153,000
Milk	$338.3 million	27 dairies
Grapes	$274.7 million	48,180
Pistachios	$270.3 million	65,300
Pollination	$171.3 million	852,000 colonies
Cattle	$153.2 million

In the 2022 Census of Agriculture, the county ranked eighth in the nation for fruit, tree nuts and berries, with 1,255 farms averaging 553 acres. The 2024 report also counted mandarins at $61.7 million on 4,600 acres, processing tomatoes at $48.3 million and figs at $34.8 million on 6,600 acres, plus 66 organic producers on more than 12,700 acres; local crops were exported to 76 countries. Ag drone spraying in Madera County centers on orchards and vineyards, with forage for the dairies.

852,000 bee colonies

Pollination brought in $171 million in 2024, with about 852,000 colonies working Madera County orchards. Every bloom-time pass is timed with the beekeeper and the label, flown early before bees are most active, and kept off hives and holding yards.

Navel orangeworm and Botryosphaeria in pistachios

UC IPM ties navel orangeworm's third flight to hull split in August, with the main pistachio spray about a month before harvest, roughly 2,100 degree-days after the first egg-laying, and earlier treatment if more than 2 early-split nuts per 100 show up in late July. For Botryosphaeria, UC IPM recommends two or three sprays starting at bloom and timed before rain, guided by spring and summer latent-infection tests. A drone treats wet orchards and block edges without a sprayer in the rows.

Grape powdery mildew risk

The UC Davis powdery mildew risk index adds 20 points for each day with six or more hours at 70–85°F, and 60 points or more means high risk. At high risk, sulfur goes on about every 7 days and DMIs every 10–14; at low risk, sulfur can stretch to 14–21 days. Oil shouldn't follow sulfur within two weeks. The Madera AVA, established in 1984, has about 31,000 planted acres, around 4,259 growing degree days and only 11–12 inches of rain a year, so mildew pressure tracks heat more than rain.

Groundwater in the Madera and Chowchilla subbasins

DWR approved the Madera Subbasin's sustainability plans in December 2023. In June 2025 the State Water Board sent the Chowchilla Subbasin back to DWR instead of placing it on probation, after more than five feet of subsidence in a decade; the county's pumping allocation there is set to fall from 25 inches to 6 over 15 years. Madera County also received a $10 million grant in 2022 to repurpose farmland around vulnerable domestic wells. Low-volume drone passes use a small fraction of a ground rig's water.

Madera Irrigation District

Madera Irrigation District serves about 140,000 acres through roughly 300 miles of canals and 150 miles of pipeline, taking Friant water from Millerton Lake through the Madera Canal, under a contract for 85,000 acre-feet of Class 1 and 186,000 of Class 2 water, plus supply from Hensley Lake. Operators map canals, laterals and reservoirs as no-spray zones and park sprinklers out of the flight path.

Glassy-winged sharpshooter watch

The county runs about 800 traps for glassy-winged sharpshooter, which spreads Pierce's disease in grapes, and treated finds in 2024 while releasing more than 900 parasitoid wasps. Vineyard passes follow the PCA's program and county guidance.
