Peanuts were sprayed 30 days after planting (DAP), 45 DAP, 60 DAP, 75 DAP, 90 DAP, 105 DAP, and 120 DAP with the fungicide. The premium program (High) was Bravo, Bravo, Fontelis, Fontelis, Fontelis, Bravo + Tebuconazole, Bravo. The reduced cost program (Low) was Bravo, Bravo, Teb + Bravo, Teb + Bravo, Teb + Bravo, Teb + Bravo, Bravo. The previous crop was peanuts. Fertility and weed control was based on UGA Extension recommendations. The plot was irrigated 1 inch per week and increased to 2 inches per week after bloom and during pod fill.

Fungicide rates:

Bravo = 1.5pts

Teb = 7.2 oz.

Fontellis = 16 oz

Statistics

Below are the statistics for the trial. There was no statistical difference in treatments with the 12Y variety. This means in the 12Y variety a $100 spray program was just as good as a $40 spray program or even no spray program. Notice the value per acre using the price per ton and subtracting fungicide cost in the far column.
