Comparing Peanut Varieties O6G and 12Y using a reduced input and a premium fungicide program.
The objective of this research was to compare the economic return when either a reduced cost fungicide program or a premium fungicide program was applied to two different varieties (Georgia-06G and Georgia-12Y). The trial was established at the Vidalia Onion and Vegetable Research Center in Lyons, GA. The experimental design was a split-plot and each combination of treatments (fungicide program X variety) was replicated three times. Both programs included seven fungicide applications. The reduced cost treatment was developed around a 4-block tebuconazole (7.2 fl oz/A)/chlorothalonil (1.5 pt/A) program. The premium treatment was developed around a 3-block Fontelis (16 fl oz/A) program with a single application of tebuconazole/chlorothalonil as above.
Plots were rated for leaf spot, TSWV, Rhizoctonia limb rot, and white mold.
Excellent rotation. No peanuts grown in three+ years.
Peanuts were planted May 20 and harvested October 29.
