Milam County agriculture: poultry, cattle and grain

The 2022 USDA Census of Agriculture counts 2,048 farms on 492,739 acres in Milam County, averaging 241 acres. Sales reached $156.4 million, ranking 41st in Texas, and 79% of that comes from livestock. Poultry and eggs lead at $62.4 million from about 1.86 million broilers. Cattle add $59.4 million from roughly 99,600 head.

Crop	Acres (2022)
Hay and forage	52,960
Corn for grain	29,961
Cotton	6,581
Wheat	5,730
Grain sorghum	3,419

Grain sales add $19.9 million and nursery products $2.8 million. With hay as the largest crop and poultry houses spread across the county, drift planning matters as much as product choice.

Milam is a regulated-herbicide county

Milam County is on the Texas Department of Agriculture's regulated-herbicide list under 4 TAC §7.53. The rules cover 2,4-D, MCPA, dicamba and quinclorac across the whole county:

• April 1 – August 31: ester formulations are prohibited, and other formulations need a TDA permit.
• September 1 – March 31: no permit is needed.
• Statewide limits: no application in wind above 10 mph, high-volatile esters prohibited within 4 miles of susceptible crops, and 2,4-D records kept for two years.

Permits expire after 180 days or once the permitted acres are treated. Licensed applicators can hold blanket permits. Neighboring counties run on different rules:

County	Rule
Falls	Same as Milam
Robertson	West of SH 6: permit April 1 – September 15
Burleson	Aerial only October 1 – February 28, not within 2 miles of susceptible crops
Bell, Williamson, Lee	Not regulated

For Milam ranches, that makes fall and winter the simplest time for broadleaf pasture work. Summer passes near cotton need the right formulation and paperwork, and the operator handles the permit check.

Cotton fleahopper and sugarcane aphid in Milam County

Cotton fleahopper. AgriLife's Blacklands threshold is 10–15 fleahoppers per 100 terminals during the first three weeks of squaring. After first bloom, treatment is rarely justified, so the window is short and timing beats product.

Sugarcane aphid in sorghum. AgriLife treats when the field averages more than 50 aphids per leaf, or when 20% of plants are infested at preboot to boot (30% from flowering to dough), and recommends spraying within one to three days. Coverage under the leaves decides how well the pass works, and the downwash from a spray drone pushes droplets into the canopy.

Southern rust in corn, stripe rust in wheat

Southern rust shows up in central Texas corn most seasons. AgriLife notes corn at milk stage or younger is vulnerable, especially late plantings, and the fungicide decision for northern corn leaf blight comes near silking. In wheat, stripe rust is common in Central Texas and has reached high levels at Blacklands trial sites, while leaf rust is less consistent. The goal is to protect the flag leaf. A drone reaches tasseled corn or wheat at heading without crushing rows or waiting for a wet field to dry.

Milam County hay meadows, stem maggot and mesquite

Bermudagrass stem maggot. AgriLife Forage Fax recommends a pyrethroid about 7 days after cutting, with a second pass 5–7 days later where infestation is heavy. In one example, control paid at about 16% damaged stems with a $12-per-acre treatment cost and $140-per-ton hay. Drones work well here: they spray right after cutting without running wheels over the regrowth.

Mesquite. Brush Busters times leaf sprays for when soil 12–18 inches deep reaches 75°F and leaves have turned dark green. The spray runs through September in most of Texas and stops by July 31 in East Texas. A mix of Reclaim plus Remedy at 0.5% each works best on plants under 8 feet. Triclopyr-based brush mixes are not regulated herbicides under §7.53. Any 2,4-D in the tank still follows the county's permit rules.

Little River bottoms and the old Alcoa land

The Little River crosses Milam County southeast through Cameron to the Brazos at Port Sullivan, and the San Gabriel joins it about 5 miles southwest of Cameron. The bottoms carry much of the corn and cotton, and floods often keep them too wet for ground rigs at spray time. Near Rockdale, about 31,000 acres of former Alcoa land in Milam and Lee counties, mostly improved pasture and farmland, sold in 2021 as Sandow Lakes Ranch. Pilots keep buffers on the rivers, Alcoa Lake and stock tanks and fly with wind blowing away from water and poultry houses.
