Brief Summary of Minutes of Annual Meeting

The regular meeting of the S-1046 was called to order at 8:40 am on Jan. 8, 2010 in New Orleans, LA by James Starr. Present: Jim Star, Richard Davis, Ed McGawley, Paula Agudelo, Bob Robbins, Sally Stetina, Jon Eisenback, Patricia Timper, and Ron Lacewell (Administrative Advisor). A. Approval of Agenda - The agenda was unanimously approved as distributed. B. Approval of Minutes - The minutes of the previous meeting were unanimously approved as distributed. C. Open Issues - starr welcomed the group to New Orleans. He mentioned that several people who planned to be at the meeting could not be here due to the frigid temperatures back home (Kathy Lawrence, Gary Lawrence, and Charles Overstreet). Lacewell expressed concern about the lack of participation and encouraged the group to apply for grant proposals. Starr queried the group about meeting times: should we continue the rotation among the member states (TX, FL, GA, LA, MS, TN, AL, AR) or attach the meeting to another conference like we did this year? Although most of the people in attendance were satisfied with S-1046 being held in conjunction with the Beltwide Cotton Conferences, it was agreed that all members should be polled via e-mail. If we continue with the normal rotation, the next meeting will be in either Arkansas or Louisiana. McGawley proposed that we perform some cooperative project as we had done in years past (but not done recently). One of the problems was that many of these projects were never published. We should indentify a common project that we can also publish. Starr said that in the Business meeting, he was planning on appointing project coordinators who might facilitate initiation and completion of one or more common projects. One idea was that we conduct a survey to identify the root-knot species associated with major crops in each participating state. D. State Reports (final year of S-1015) Arkansas. Bob Robbins presented a project involving rotating soybean cultivars containing different resistance genes. Soybean cyst populations have been kept at low levels for 7 years. He has also been screening soybean lines from all over for resistance to the reniform nematode. ARS Georgia. Richard Davis developed a new cotton line (GA120R1B3) with a high level of resistance to Meloidogyne incognita and improved yield and fiber quality. This was achieved through backcrossing and single seed descent. A germplasm release should be completed very soon. Patty Timper discussed two projects with Pasteuria. In one project, endospore densities increased to higher levels in a rotation with eggplant, corn, and peanut than in other crop rotations. The other project involved the effect of soil texture and nematicide treatment on a Pasteuria infecting reniform nematode. ARS Mississippi. Sally Stetina presented several project dealing with reniform nematode in cotton. She is looking for new sources of resistance from hirsutum and other Gossypium species and evaluating molecular variability in the reniform nematode (microsatellite and SSR). She has found no link between variation and virulence or pathogenicity. Louisiana. Ed McGawley is testing Agri-Terra and sister products on strawberry as an alternative to methyl bromide. The product controls both M. hapla and ring nematode. He has also been testing a chemical called Oraphyte and Pasteuria in turf. Virginia. Jon Eisenback presented the findings of surveys of nematodes in soybean (mostly SCN) and corn (stunt, stubby root, lesion, and root-knot nematodes). He has also found a new root-knot in turf  M. lamicainae. This nematode has subsequently been found in other mid-Atlantic states. Damage threshold  40/100 cm3. South Carolina. Paula Agudelo has an interest in intraspecific diversity of nematodes (mainly root-knot and reniform nematodes) and how this diversity influences management. She presented research on the effect of temperature on embryogenesis of the reniform nematode. She also has a study looking at the effect of crop rotation on the population structure (utilizing 7 microsatellite markers) of the reniform nematode. Corn has the greatest impact on the population structure, perhaps by selecting for survival of different genotypes. Texas. Jim Starr is attempting to identify difference sources of resistance to M. incognita in cotton. He has conducted a half diallel analysis with 5 resistant cotton accessions from Mexico and identified at least 2 unique resistance alleles. He is also trying to develop cotton germplasm with resistance to both root-knot and reniform nematodes. In the near future, he plans to release a high O/L peanut cultivar with good resistance to root-knot nematodes, Tomato Spotted Wilt, and Sclerotinia blight. E. Business meeting Bob Robbins (Arkansas) was unanimously approved to be the next Chair of S-1046. Ed McGawley was unanimously approved to be the next Secretary. As a general rule, the secretary will be selected from the rotation 1 year out from the Chair. Starr asked for volunteers to coordinate each of the three objectives. These coordinators would organize the common projects and develop uniform protocols. Stetina volunteered to coordinate Obj. 2 and Agudelo and Eisenback volunteered to coordinate the reniform and root-knot projects, respectively, for Obj. 3. No one was selected for Obj. 1 (Management) because the group did not think this objective was amenable to a common project. Stetina suggested that we use SharePoint for sharing files and information over the internet. This program would be particularly useful once we establish common projects. Adjournment:Meeting was adjourned at 3:45 pm by Jim Star. Minutes submitted by: Patricia Timper

As this is a new project there are no research accomplishments to report at this time. Participants have completed their initial organization into interest groups and individuals have been selected to coordinate regional collaborative efforts under objectives 2 and 3.
