Sample Abstract

RESILIENCY OF A NEMATODE COMMUNITY AND SUPPRESSIVE SERVICE TO TILLAGE AND NEMATICIDE APPLICATION. Timper, Patricia1, R.F. Davis1, and G. B. Jagdale2. 1USDA ARS, P.O. Box 748, Tifton, GA 31793, 2Plant Pathology Dept., University of Georgia, Athens, GA 30602.

We hypothesized that populations of predatory and omnivorous nematodes would be slower to recover from conventional tillage and nematicide application than other nematode trophic groups, and that lower populations of predators and omnivores would lead to greater survival and reproduction of plant-feeding nematodes (i.e., pest resurgence). A field study was conducted from 2008-2010 with two tillage regimes (strip and conventional) and two nematicide treatments (the fumigant1,3-dichloropropene and a no-nematicide control) with six replications. Soil samples were collected pre-fumigation, post plant, and mid season during each year. Tillage had little impact on the nematode community, but 1,3-D reduced numbers of all trophic groups compared to the control at post plant and mid season. Omnivores and predators were not severely impacted by the nematicide treatment; populations of both groups repeatedly recovered by the following spring from the yearly application of 1.3-D, with the exception of predators in 2008. We used two bioassays to measure the suppressive service of the soil community: one determined survival of the reniform nematode (Rotylenchulus reniformis) and the other reproduction of Meloidogyne arenaria on peanut. Survival of R. reniformis was greater in defaunated compared to native soil indicating that the soil contained organisms that consumed nematodes. Application of 1,3-D led to an increase in survival of the R. reniformis from 53% in the control to 78% in treated plots at post plant, and from 55% in the control plots to 66% in treated plots at mid season. Likewise, reproduction of M. arenaria was greater in soil treated with the nematicide. At post plant, survival (%) of R. reniformis was negatively correlated with abundance of predators + omnivores. Organisms other than nematodes were likely involved in the suppressive service. This was particularly evident at pre-fumigation, when survival of R. reniformis was lower in plots previously treated with 1,3-D than in control plots. The nematicide may have altered the soil community to allow a fungal, bacterial, or invertebrate antagonist of nematodes to increase in abundance.

INSTRUCTIONS FOR POSTER PRESENTATIONS

Each poster will be given a number and allotted a space 90 cm wide x 110 high (or 35 inches x 43 inches). The spaces will be numbered ahead of time so that you will know where to place your poster. Pushpins will be provided for mounting the poster.

Indicate the title, and name(s) of author(s) at the top of your poster so that it may be identified easily; the lettering for this heading should be at least 1″ (30.5 cm or 72 points) high.

As a general guideline, text and illustrations should be comfortably read from a distance of 3 to 4 feet (or 1 m), so make them large enough to be seen clearly. Charts, drawings, photographs and illustrations might well be similar to those used in making slides and more heavily drawn. Simple use of color can effectively add emphasis. Your poster should be printed on lightweight materials that could be supported by pushpins. Hand-lettered material is generally unsuitable for professional and effective poster presentation. Typed material should use the largest font possible, but at least 30 points in size. Illustrated materials should be kept simple. It also might be useful to have small copies of the poster for handouts, and a tablet of suitable sketch paper as well as a felt marker to use in discussion and further illustration.
