OBJECTIVE
Determine pepper tolerance to Sandea applied precision-directed, topical, or under plastic.
TreatmentsUnder plastic
• 0.5, 0.75, 1.0 ounces Sandea per Acre
• 4 replications per treatment
* All Treatments Contained 0.25% NIS by Volume
TreatmentsOver-the-Top and Directed
• 0.5 ounces Sandea per Acre
• 4 replications per treatment
* All Treatments Contained 0.25% NIS by Volume
Application Information
• Plots = 6 ft. by 15 ft.
• 20 or 14.8 GPA spray solution
• Directed treatments precision applied to lower 25% of plant canopy
• Injury ratings measured
• Three harvest dates

Conclusions
• Pepper tolerance to topical Sandea applications is unacceptable.
• Directed applications most likely unacceptable.
• Additional research focusing on Sandea under plastic is needed but tolerance and
nutsedge control is questionable.
