Abstract
Peanut growers must find acceptable means to optimize yields while minimizing costs associated with production. Disease management using fungicides is the single greatest expense associated with peanut production in Georgia. This research is to find the efficacy of ELAST 400F (Dodine) as compared to other leaf spot fungicides in peanuts. This was critical in 2009 because ELAST 400F (Dodine) was a new fungicide and one of the least expensive options to growers. Using the 2009 Peanut Fungal Disease Risk Index, this research was established on River Bottom Farms in Lanier County Georgia in a field with low-to-moderate disease risk (irrigated, long rotation, twin-row minimum tillage, 06G variety) for fungal disease. Thirteen fungicide programs were included in the study. These plots were randomized complete block experimental design with four replications. They were managed according to production practices recommended by UGA Cooperative Extension. Tomato Spotted Wilt Virus was not statistically different among all treatments. Headline, ELAST and Provost were the best leaf spot treatments. Abound treatments were statistically the best white mold treatment. Full season Artisan produced the highest yield. The cost per acre for treatments ranged from $42.66 (full season Tebuconazola plus chlorothonil) to $113.01 (full season Abound).
