3. Introduction
Grain Sorghum/Sugarcane Aphid Insecticide Seed Treatment Test
Interpretive Intent
Determine the efficacy and residual activity of neonicotinoid seed treatments towards sugarcane aphids in seedling grain sorghum
Determine if protecting seedling grain sorghum from aphids results in an increase in yield (optional)

4. Materials & Methods
Grain Sorghum/Sugarcane Aphid Insecticide Seed Treatment Test
Plant seed treatments and/or In-furrow sprays
Agronomic data
Aphid counts (seasonal)
Yield (optional)

20. Picture Slide

21. Key Learnings Sivanto in-furrow consistent
Seed Treatments Imperative but performance inconsistent among locations
Will require additional foliar treatments
Results depend highly on infestation timing/Early vs Late
Yield dependent on severity and duration of infestation

22. Next Steps Expanded Testing of Sivanto in-furrow Yield is necessary
Soil type/Rain may influence longevity
Greatly simplify protocol
