Chapin says Bailey is truly an outstanding variety, but growers can take best advantage of its many benefits by following some simple guidelines.

He says:

• Unless grown for seed, use Bailey on the worst white mold and CBR fields you have. Based on 5 years of tests at the Edisto Research Center in Blackville, S.C., soil disease resistance is the greatest strength of this variety. Bailey has a very impressive level of white mold resistance and though not immune to CBR, it is better than anything else we have;

• There are three reasons to plant Bailey first: very good virus resistance, excellent white mold resistance, and shorter maturity for an early start on digging;

• Be aware of maturity. Bailey can be 7 days earlier than NC-V 11;

• Be prepared to add a pyrethroid to a fungicide spray (typically in July) if you see hopper burn starting on field edges. Bailey is more susceptible to leaf hopper feeding, but this is an easy problem to solve. Hopper burn on field edges is not a big deal; just don’t let it spread across the entire field;

• Don’t be surprised if Bailey grows a bigger “bush” than any peanut variety you have seen. A guidance system will find the rows, but some growers have reported problems inverting them because of the vine size; others have had no problems;

• Fungicide programs: Even though Bailey is less susceptible to white mold and late leafspot than any other available variety, Bailey must be protected from leaf spotdefoliation and has also shown a consistent yield response to soil fungicides in our tests.

• For now, the minimum fungicide program should be: 45 DAP: Bravo 1.5 pt; then tebuconazole (generic Folicur) plus Bravo 1 pt at 60, 75, 90, and 105 DAP. We will be working with growers to test some 4-spray programs using longer residual leaf spot materials. CBR: Fields with a history of severe CBR should be treated with a combination of Proline in-furrow and variety resistance (Bailey, Perry, or Georgia Greener).

• No variety is perfect. We believe that Bailey will be an important variety for us in South Carolina because it can protect us from white mold control failures along with reducing our susceptibility to CBR, tomato spotted wilt and late leaf spot.

• But, as with any new variety, have realistic expectations. We never really know what a variety will do until it’s planted on large acreage. Bailey has a lot of yield in it and has been near the top even in our tests with no soil disease pressure, but we have also had low disease tests where standards (Champs, NC-V 11) beat it. Bailey shines under high soil disease pressure.

As growers head into planting season there is plenty of uncertainty as to how much their peanut crop will be worth. With that in mind, choosing a variety with the flexibility to allow growers to cut back on crop protection costs without significantly jeopardizing yield is a big advantage.
