  1. Eggplant Response to Topical and Precision-Directed Applications of Sandea (Halosulfuron) Tim Flanders And Stanley Culpepper The University of Georgia

  2. OBJECTIVE • Determine the Tolerance of Eggplant to various rates and application methods of Sandea Herbicide

  3. TreatmentsOver-the-Top and Directed • 0.5 ounces Sandea per Acre • 1.0 ounces per Acre • 4 replications per treatment * All Treatments Contained 0.25% NIS by Volume

  4. Application Information • Plots = 6 ft. by 15 ft. • 9 to 11 leaf stage, 5 week old plants • 14.8 GPA spray solution • Directed treatments precision applied to lower 25% of plant canopy • Damaged ratings taken 7 and 12 DAT

  5. Untreated Check

  6. 0.5 Ounces Over-the-Top Seven DAT

  7. Conclusions • Eggplants do not have the tolerance of tomatoes or many cucurbits and damage from any rate or treatment methods is unacceptable. • More research is needed to determine tolerance when Sandea is used as a soil application between the bed forming and plastic laying operation. • Plasticulture vegetable production will have to be a crop specific systems approach when controlling weeds, nematodes, and soil-borne diseases.
