1 Crisp County Ag News UGA Extension Crisp County 110 West 13th Avenue, Suite C, Cordele, GA / (P) / (f) Pecan Federal Marke ng Order On March 8, the USDA mailed ballots to pecan growers in the 15 states that produce pecans. Beginning on March 9 and ending on March 30, growers will have the opportunity with their vote to express their preference for acceptance of the Federal Marke ng Order for Pecans. In addi on to expressing their preference, voters will indicate their average in shell produc on over the four produc on years of 2011, 2012, 2013, and The FMO can be approved in one of two ways. Either 2/3rds of those growers vo ng approving the measure or 2/3rds of the volume of produc on vo ng in approval will cause the FMO to pass. The qualifica on for a grower to vote in the Referendum is either 50,000 in shell pounds of average produc on over the four years OR 30 pecan acres, including planted acreage not yet in produc on. If a grower does not receive a ballot by Monday, March 14, he or she should contact the Southeast Marke ng Field Office of USDA at the phone number noted below to have a ballot mailed: (863) GA Pecan Growers Educa onal Conference and Trade Show Register now for this informa ve event to be held March 29 30, 2016 at the GA Na onal Fairgrounds and Agricenter: Click the blue link for details and registra on informa on: h ps://

Timely Notes on Disease Management for 2016 (Dr. Bob Kemerait UGA Extension Plant Pathologist) Though s ll approximately 6 weeks away from the general start of the plan ng season, there are issues regarding management of diseases and nematodes affec ng peanut that deserve a en on now. 1. Choosing the right variety. Most of our acreage will be planted in Georgia 06G and this con nues to be an excellent variety. I recognize that seed for Georgia 12Y is generally unavailable; however I encourage growers who are concerned about white mold to plant some if they can. Likewise, growers with root knot nematode problems are encouraged to consider plan ng at least some of their acreage in Tifguard or Georgia 14N, remembering that Georgia 14N is a later maturing variety. Growers are encouraged to consult the 2016 version of Peanut Rx to deter

5 mine the predicted risk to tomato spo ed wilt, white mold and leaf spot diseases given the variety they plant and their produc on prac ces. With this informa on they can make a be er informed decision on their disease management program. 2. Decisions regarding nematode control are cri cal now. Growers who an cipate a problem with peanut root knot nematodes and who plan to apply a nema cide will likely use Telone II or Velum Total. The primary considera on in choosing between a resistant variety, Telone II and Velum Total is the size of the popula on of nematodes in a field. The economic threshold number, that magic number that draws the line between when damage from the nematodes is worth trea ng and when it is not is 10/100cc soil. Velum Total (18 fl oz/a) is generally recommended where a grower would have used Temik 15G, 10 lb/a at plant, which would coincide with low to moderate nematode popula ons. Defining low to moderate popula ons is unse ling, but I would say anywhere from root knot nematodes per 100cc soil in a FALL collected sample would be in the ballpark. As numbers increase beyond 100/100cc soil, I think a resistant variety or Telone II becomes increasingly important. Also, given that the root knot nematodes are generally clumped in a field, it is likely that even a field described as low to moderate will have significant hot spots in it. Telone II should be applied in row at 4.5 gal/a in row days ahead of plan ng with special awareness of soil condi ons during this El Niño season. The possibility of frequent rain events could make fumiga on challenging. An insec cide for management of thrips is s ll required when Telone is used but not when Velum Total is applied. Velum Total should be applied at 18 fl oz/a for peanuts and the product can be mixed with other fungicides and inoculants without concern. Whether choosing Telone II or Velum Total, accurate calibra on and precise applica on are cri cal for maximum success. Growers should ensure that equipment is properly put together and tested for calibra on. 3. By now, most growers are aware that Tilt Bravo will be generally unavailable this season and the issues concerning sale of peanuts treated with propiconazole (the ac ve ingredient in Tilt) to the European market could affect other products as well. For example, it is not clear how Ar san, a combina on of flutolanil and propiconazole will sold this season; however Convoy (flutolanil alone) will be in ready supply. Syngenta will likely recommend a tank mix of Bravo and Alto to replace Tilt Bravo; products like Priaxor will also perform well in this early season spot. As we move beyond plan ng, addi onal discussion regarding leaf spot management will be proposed. 4. White mold is of special concern this year, both because of an cipated short rota ons and because of the severe outbreak we had last year. Growers are reminded that early season applica ons of Proline and, perhaps, Elatus can help to manage this important disease. Banded applica ons are typically made approximately 3 5 weeks a er plan ng. NO FUNGICIDE PROGRAM CAN MAKE UP FOR SHORT ROTATIONS. However using the right products at the right me sure can help

6 Wheat Foliar Disease Update 2016-March Wheat Leaf rust. Leaf rust (Puccinia triticina = syn P. recondita) has been reported and identified in several counties. It is early on its arrival, but favorable environmental conditions for leaf rust development are developing or are now in place in the state; therefore wheat field scouting and monitoring should be implemented at this time. If leaf rust is present in your field, this warrants a fungicide application. Options include: Triazoles metconazole (Caramba) propiconazole (Tilt, Propimax) prothioconazole (Proline) prothioconazole + tebuconazole (Prosaro) tebuconazole-containing products (Folicur, others) Strobilurins azoxystrobin (Quadris) fluxastrobin (Evito) picoxystrobin (Aproach) pyraclostrobin (Headline) Mixed mode of action fluoxapyroxad + pyraclostrobin (Priaxor) flutriafol + fluoxastrobin (Fortix) propiconazole + azoxystrobin (Quilt, QuiltXcel) propiconazole + trifloxystrobin (Stratego) prothioconazole + trifloxystrobin (Stratego YLD) pyraclostrobin + metconazole (Twinline) tebuconazole + trifloxystrobin (Absolute) tebuconazole + azoxystrobin (Custodia) When leaf rust has become established in a field, triazole fungicides tend to be most effective. Strobilurins have a more preventive activity and tend to be weaker if rust already in the field.
