The Texas Department of Agriculture has granted the suspension of a rule regarding the application dates of 2,4-D in Wharton County – Section 7.53(oo)(1) and (2) of the special provisions for Wharton County of the Texas Pesticide Laws and Regulations.  The suspension allows for the ground application of 2,4-D and 2,4-D containing herbicides by permit on the west side of the Colorado River in Wharton County beginning on Saturday, September 1, 2018.    Ground applications of 2,4-D on the east side of the Colorado River in Wharton County are already permissible under rule 7.53(oo)(1).  All other applicable rules for Wharton County continue in effect.  Pesticide applicators are urged to pay special attention to 7.53(oo)(4) “In no case shall 2,4-D be used to treat any area that is nearer than two miles to any susceptible crop”.  Pay close attention that this rule suspension granted by TDA only allows the application of 2,4-D by ground application only beginning September 1st.  The aerial application of 2,4-D in Wharton county continues to be prohibited until September 15th on the east side of the Colorado River and  until October 1st on the West side of the Colorado River.  Also note in rule 7.50 (b) (3) that the use of any turbine or blower-type ground application equipment to apply regulated herbicides is prohibited.


Also, in a regulated county such as Wharton County, no person shall spray regulated herbicides (2,4-D, dicamba, MCPA, or quinclorac) when the wind velocity exceeds 10 miles per hour or as specified on the product label, if the label is more restrictive.  Regulated Herbicide Spray Permit applications are available at the Wharton Co. Extension Office, or by logging-on at

TDA Pesticide license holders are required to submit a regulated herbicide spray permit when 2,4-D, dicamba, MCPA, or quinclorac will be sprayed in a regulated county.  The submission of the regulated spray permit pertains  to 2,4-D, but also when spraying dicamba, MCPA, or quinclorac in Wharton County.  Completed Regulated Herbicide Spray Permit applications can be faxed to the TDA Regional Office in Houston at (888) 223-5606.
