Sorghum, corn, cotton and cattle

AgriLife counts more than 85,000 acres of row crops in Jim Wells County, mostly corn, grain sorghum and cotton. The 2022 Census of Agriculture recorded:

Crop or livestock	2022
Grain sorghum	22,829 acres
Corn	10,883 acres
Cotton	10,610 acres
Hay and forage	8,703 acres
Southern peas	6,475 acres
Cattle	28,174 head

Farms are getting fewer and larger: 960 in 2022, down 22%, averaging 415 acres. Drone spraying in Jim Wells County covers row crops in spring and summer and brush in fall.

Sorghum: aphids, midge and armyworm

AgriLife entomologists in the Coastal Bend advise checking sorghum for sugarcane aphid twice a week, since aphids move in from Johnsongrass. Sorghum midge is scouted two to three times a week from head emergence through bloom, and fall armyworm is treated once leaf loss passes 30%. A drone treats headed sorghum without driving down rows.

Cotton, the last crop planted

Cotton goes in last in South Texas, after corn and sorghum, and the Valley-to-Coastal Bend cotton belt runs under boll weevil eradication rules. TDA sets stalk-destruction deadlines by zone starting September 1, so defoliation and harvest timing matter. Drones apply harvest aids on fields bordered by brush or homes.

Huisache and brush

AgriLife ran a huisache control trial in Jim Wells County, and its Brush Busters guidance treats huisache with leaf sprays from September to November, until soil at 12 inches cools below 75°F. Mesquite, prickly pear and huisache crowd pastures and field edges; drones spot-spray scattered plants from mapped coordinates or broadcast dense regrowth where labels allow.

Drought and dry springs

In October 2025, the National Weather Service had northern Jim Wells County in moderate drought, September rain at 25–75% of normal, an active burn ban and early hay feeding across the Coastal Bend. Lake Corpus Christi and Choke Canyon together held about 12% of capacity. Dry years shift weed and pest timing, so passes are booked on scouting, not the calendar.

Lake Corpus Christi and the Nueces

Lake Corpus Christi, about 19,000 acres on the Nueces River where Jim Wells, Live Oak and San Patricio counties meet, is Corpus Christi's main drinking-water supply. Operators map the lake, river, creeks, stock tanks and homes as no-spray zones and check FieldWatch's DriftWatch and BeeCheck before every job.

Herbicide rules next door

Jim Wells County isn't on TDA's regulated-herbicide list, and neither are Nueces, Kleberg, Brooks, Duval or Live Oak. San Patricio County to the east is regulated: no permit is needed from August 15 to March 1, and 2,4-D amine applications there carry row and distance buffers that grow with wind speed. Fields across that line are checked before booking.

Minor crops and auxin care

Sunflowers, watermelons, southern peas, sesame and wheat make up less than 15% of planted acres in Jim Wells County, but they sit next to sorghum and cotton fields that get herbicide passes. AgriLife held an auxin herbicide training in the county with 49 participants, a sign of how seriously local growers take drift. Operators map sensitive crops before any herbicide job, choose coarse droplets and fly only in light wind blowing away from them.

Texas licensing and airspace

The Texas Department of Agriculture (TDA) requires a Commercial Applicator license, $200 a year, with the Aerial category plus another use category, and continuing education. Alice International Airport has Class E airspace starting at 700 feet, and operators check airspace for every field. The FAA requires Part 107, Part 137 and a Section 44807 exemption for drones of 55 pounds or more.
