Dryland grain and pulses

Latah County had 989 farms on 324,990 acres in the 2022 Census of Agriculture, with $101.5 million in sales, 96% from crops. Only 424 acres were irrigated.

Crop	2022 acres
Wheat	89,496
Hay and forage	30,154
Chickpeas	21,954
Canola	11,210
Barley	7,928

Grain, oilseed, dry bean and dry pea sales of $76.7 million ranked eighth among Idaho's 44 counties, and the county ranked third for Christmas trees. About 70 farms top 1,000 acres. Cropland covers 228,085 acres, with about 43,700 acres of pasture and 39,900 of woodland, and only 7% of farms plant cover crops. Drone spraying in Latah County centers on wheat, chickpeas and canola on steep, dryland ground.

Idaho's new drone license category

From July 1, 2026, the Idaho State Department of Agriculture (ISDA) requires a new Aerial UAS Pest Control (AU) category to apply any pesticide by drone, including for private applicators. A for-hire operator spraying crops needs Core, AU and Agricultural Crop categories, the licensed operator must be on site, and FAA Part 107 and Part 137 don't replace the state license. Every crew working in the county carries all three.

Stripe rust in 2026

WSU's March 2026 forecast for the eastern Pacific Northwest predicted 55.8% yield loss on highly susceptible wheat, in the upper range of a severe epidemic. WSU advised adding fungicide to the herbicide pass when rust is active and possibly a second pass 20–30 days later. A drone makes both passes on hills without crushing the stand.

Resistant Italian ryegrass

In a survey of 75 fields in northern Idaho and eastern Washington, 73% had Italian ryegrass with some resistance to Group 1 herbicides, up to 55% resisted Group 2, and 7% showed multiple resistance. Product choice and timing follow your agronomist's resistance plan, and drones can treat patches without a full-field pass.

Pea leaf weevil and pea aphid

University of Idaho guidance calls for checking 10 seedlings at each of 10 sites for leaf notching; action may be needed when 30% or more of plants are damaged. Adults move into pea and faba bean fields once temperatures reach about 55°F, and foliar sprays work best before egg-laying. Pea aphids also spread pea enation mosaic and bean leafroll viruses in Palouse lentils, so early scouting decides the pass.

Cabbage seedpod weevil in canola

The Canola Council's threshold for cabbage seedpod weevil is 25–40 weevils per 10 sweeps, with spraying at 10–20% flower. A drone treats flowering canola without wheel tracks and can fly early, before pollinators are most active.

Steep loess hills

WSU's conservation research found all original topsoil gone from about 10% of Palouse cropland and 25–75% gone from another 60%, with up to 200 tons per acre lost in a single winter on steep slopes. Organic matter in the eastern Palouse fell from 4.5% to under 2%. Only 12% of farms use no-till. A drone follows the terrain on slopes where ground rigs slip and leave ruts that start rills.

Prairie remnants and catchfly

Spalding's catchfly, a federally threatened plant, grows in Palouse prairie remnants, and a survey found only 35 acres across 103 sites in the county that qualify as Palouse grassland remnants. Operators map remnants, field edges and timber as no-spray zones and fly only with wind blowing away from them.

Research farms and the pulse industry

The University of Idaho's 220-acre Kambitsch Farm, north of Genesee, runs dryland pest and no-till studies, and the USA Dry Pea & Lentil Council is headquartered in Moscow. The National Lentil Festival, founded in 1989, is held just across the line in Pullman. The region's share of U.S. lentil production fell from over 98% in 1989 to about 18% by 2017 as northern plains acres grew, but pulses remain central to Palouse rotations.

Timber, towns and airspace

The county covers 1,077 square miles and had 39,517 residents in 2020, with cropland in the west and south giving way to timber and part of the St. Joe National Forest in the north and east. Pullman-Moscow Regional Airport, just west of the state line, opened a new, longer runway in 2019. Crews check airspace for fields near Moscow and keep work on farmland.
