About 41% of farms are 10–49 acres. Crop spraying in Hill County covers wheat in spring, corn and sorghum in summer and cotton through defoliation.

Cotton pests in the Blacklands

• Fleahopper: watch closely at pinhead square in June; AgriLife field tests found sprays held them for only five to seven days.
• Bollworm: pyrethroid resistance roughly doubled in one June season, so AgriLife leans toward diamide products like Prevathon or Besiege, and Bt resistance is suspected.
• Spider mites: in dryland cotton, treat when 30–40% of plants show reddening.
• Late season: growth regulator mid-season, then harvest aids and defoliation from August into September.

Sorghum and sugarcane aphid

Sugarcane aphid doesn't overwinter in North Texas; it blows in each spring, and 50 aphids per leaf can become 500 in two weeks. AgriLife's threshold is 50–125 per leaf; scout weekly, then twice a week once aphids appear. Headworms are checked at bloom.

Wheat and corn

Wheat fungicide goes on from flag leaf to heading in March and April, when leaf rust shows up. Corn gets fungicide at tassel in wet years, and Bt corn ears are scouted for bollworm. A drone flies over tall corn and headed wheat without wheel damage.

Herbicide-resistant waterhemp

Texas A&M weed scientists have confirmed glyphosate-resistant waterhemp in Texas row crops. Layered residuals and early post passes are the base program, and drones handle rescue passes when black clay is too wet for ground rigs.

Rules at the McLennan County line

Hill County isn't on TDA's regulated-herbicide list, but McLennan County to the south is. There, ester formulations of regulated herbicides are banned from April 1 to August 31, and other formulations need a permit in that window. In regulated counties, spraying stops above 10 mph wind and volatile esters are banned within 4 miles of susceptible crops. Fields that touch the McLennan line are checked before booking.

Black clay to the east, Grand Prairie to the west

Field condition	Ground sprayer	Spray drone
Blackland gumbo after rain	Bogs down	No soil contact
Cracked clay in dry spells	Rough ride, boom bounce	Steady height
Corn at tassel	Crop damage	Flies above the canopy
Cotton at defoliation	Damages open bolls	No crop contact

Aquilla Lake sits in the center of the county, and Lake Whitney and the Brazos form the western edge. Operators map lakes, creeks and homes as no-spray zones and check FieldWatch's DriftWatch and BeeCheck before every job.

Pasture weeds and brush

Pasture covers about half of Hill County's farmland. KR bluestem, broomweed and Johnsongrass are the common targets, and mesquite and honey locust spread on the western side. Mesquite leaf sprays usually go on in May and June, when trees are in full, dark-green leaf.

Small tracts between Dallas and Waco

With Interstate 35 running through Hillsboro, Hill County draws buyers of 10- to 50-acre tracts from the Dallas–Fort Worth and Waco areas. Many of these places run a few cows or cut hay and need one or two weed passes a year rather than a full crop program. A drone handles those small pastures, fence lines and creek bottoms without hauling a ground rig across town. Operators check whether the land carries an agricultural valuation, map houses, gardens and stock tanks as no-spray zones, and leave an application record the owner can keep with their ag-use file.

A Hill County spray year

Window	Typical drone work
March to April	Wheat fungicide at flag leaf to heading
May to June	Mesquite, cotton fleahopper, sorghum aphid scouting
June to July	Corn fungicide at tassel, bollworm
July to August	Spider mites, cotton growth regulator
August to September	Cotton defoliation, cover crops

Texas licensing and airspace

The Texas Department of Agriculture (TDA) requires a Commercial Applicator license with Category 9 (Aerial) plus a use category such as Field Crops or Pasture and Rangeland, with five continuing-education credits a year. Hillsboro Municipal Airport sits north of town, and the Waco airports' controlled airspace lies mostly south of the county. The FAA requires Part 107, Part 137 and a Section 44807 exemption for drones of 55 pounds or more.
