Small and mid-size places

Farm size	Farms
10–49 acres	830
50–179 acres	1,098
180–499 acres	443
1,000 acres or more	83

About three in four farms run under 180 acres. Many are family places with a hay meadow, a few pastures and a creek, so neighbors along the same road often group their jobs into one trip.

Huisache in the fall

AgriLife's huisache leaf-spray method starts in September, once late-summer growth stops, and runs into November or until soil at 12 inches cools below 75°F, with expected kill of 76–100%. Seeds spread with livestock, so pastures need yearly checks. In a South Texas broadcast study, aerial treatment killed 69% of plants under 2 meters but only 40% of taller plants, and mortality was highest after more than 50 mm of rain in two weeks; droplets near 400 microns gave 85–99% kill. Treating huisache while it's small pays. Some huisache products are limited to private rangeland and can't go on hay fields, so the label decides what goes on each pasture.

Macartney rose on clay

Macartney rose spreads across high-clay soils from Southeast Texas into the Middle Coastal Prairie. AgriLife recommends spraying in spring once soil reaches 75°F at 12–18 inches, pausing during flowering and hip formation, then resuming in late summer and fall, with 76–100% kill on actively growing plants. Skip plants under three feet and anything mowed in the last 9–12 months.

Bermudagrass stem maggot

Stem maggot damage shows as dead top two or three leaves that look frost-burned. If it appears one to three weeks after a cutting, AgriLife advises cutting and removing the crop, then protecting regrowth with a labeled pyrethroid. Grazed pastures show less damage than hay meadows, so the hay fields get scouted first.

Claypan, blackland and post oak

The north of the county is Blackland Prairie and the south Post Oak Savannah, between about 150 and 350 feet in elevation. A dense claypan subsoil holds water at the surface after rain, so hay meadows stay soft for days. A drone treats them without ruts or compacted ground. Cotton faded in the early 1900s after the boll weevil, and oil was found in 1941. Created in 1846, the county covers about 970 square miles and had 20,337 residents in 2020.

The Lavaca and Navidad

The Lavaca River runs southeast past Moulton and Hallettsville, and the Navidad passes Sublime and Speaks on its way to Lake Texana. Operators map both rivers, their creeks and stock tanks as no-spray zones and use only products labeled for use near water.

Czech and German farm heritage

About a third of residents trace German ancestry and nearly as many Czech. Shiner's Spoetzl Brewery dates to 1909, Yoakum was once called the tomato capital of South Central Texas, and Hallettsville stands on land donated by Margaret Hallett. Family farms still pass down through those communities. The AgriLife Extension office in Hallettsville offers local guidance on brush, forage and pasture weeds.

Licensing and county rules

Drone applicators need a Texas Department of Agriculture (TDA) commercial applicator license, and the business holds an FAA Part 137 certificate with Part 107 pilots. Lavaca County is not on TDA's regulated-herbicide list, but neighboring Jackson County is, so crews check rules on jobs near that line.
