Minutes for S1011 Meeting
Virginia Tech, June 9-10, 2005

Tom Mueller opened the meeting up with a discussion of the agenda. Need to change the agenda due to several people needed to leave early tomorrow. Need to spend a majority of the time looking at the data and work on the development of tables, followed by the state reports, and a discussion of when/where to meet next year. Decided to change the agenda and move the state reports to 10:45 am.

Lissa Riley presented copies of the research paper that was recently accepted by Journal of Agriculture and Food Chemistry concerning previous work conducted by the group.

Clarence Watson, Administrative Advisor, discussed the requirements that he needs to have fulfilled. The minutes need to be sent to him right after the meeting. Minutes will go on the NIMSS website. There was a move this year to eliminate all multi-state research funds in the federal budget, which would have seen fewer multi-state projects but now looks unlikely to be passed. For next year will probably be going back to formula funding.

John Hess, previous department head of the Department of Biochemistry, served as the official representative on the S1011 project at Virginia Tech after Roddy Young retired welcomed the group to Virginia Tech. In January this year he became the interim Dean which he will probably be doing for another year. He stated that when he became involved in the project. He was impressed with the group and could see that something was actually getting done within the group.

Virginia Tech is now a covered (not public) university  they are trying this to get more independence concerning purchasing and hiring and less restriction on tuition control. They have to assess the contribution of the university to students. The personnel are still a part of the state pension system. The change has resulted in more autonomy in raising tuition. In questioning members of the group, most universities among the group had seen tuition up somewhere in the 5-10% range. Seeing more agriculture related families having problems getting their children into the universities. Virginia Tech has an agriculture undecided major that students can come into. College of Agriculture at Virginia Tech has around 2000 students. The Dean of Undergraduate School would like to increase the number to 2200.


Discussion concerning development of the paper/data related to current year's research:

The order of the authors was decided Jean Cobb will the first author, John Mattice - second author, Scott Senseman - third author. Joe Massey will not be an author because he was unable to conduct the test this year. Tom Mueller will be the last author.

Possible Title: Elevated temperatures and extended time intervals affect pesticide recovery from water and solid phase extraction disks in a multi-laboratory study simulating shipping conditions of water

Various technical aspects of the paper were discussed.

State reports from members of the group were presented:

John Mattice - Arkansas
Char is being tested in vegetative filter strips to see if it will help remove pesticides from runoff water. The chars are 600 to 8000 more absorptive than soil toward diuron.

We are using aluminum trays that are designed to allow user to collect leachate water and surface runoff water. Burned Bermuda grass was used as the char - char decreased the amount of diuron and chlorthalonil in runoff water even though it only has a few minutes of contact with the char. Chlorthalonil was absorbed approximately 3 fold faster than diuron. When char was used there was more runoff water and less leachate. Not sure why there is this difference in the amount of runoff/lechate. The char may plug pores in the soil decreasing leaching.

Comparison of using DVB disks instead of C18 disks. DVB shipped with isopropanol to retard microbial growth. The DVB disks can be flushed with methanol and water before going to the field. You don't have to leave the small film of methanol on disks prior to adding the water samples through the disks which is convenient.

A test of the field extraction unit using the DVB speedisk showed it worked well. Recovery of cyhalofop-butyl was enhanced by immediately transferring it to the disk instead of leaving it in water. There were significant losses of cyhalofop-butyl from water after one day.

Monitoring pesticide runoff associated with rice production.
Also conducting some work with antibiotics from chicken litter - used cyano Speedisks and Oasis cartridges - no real way to predict what will work on which disks, found some bacitracin and monencin in litter.

Jose Dumas - University of Puerto Rico
Project T89 - Studying volatile compounds that are produced by sweet potatoes during cooking

Project z177 - Looking for heavy metals and soil absorption ratio - particularly lead and copper

Project zts27 - Looking at pesticide absorption in carbonatic soils

Tom Mueller - University of Tennessee
Several projects related to pesticide fate in the environment and weed resistance to glyphosate

Jean Cobb - Virginia Tech
Facility is mainly a service center - recently had a sophomore undergraduate research student who wanted to get some experience in pesticide analysis - used Quencher's method for the extraction of coumaphos and fluvalinate in honey, working with Rich Fell who has 10 sites in state involving the growers.

Fullbright scholar - looking at organochlorine pesticides and PCB's Investigating turtle livers from turtles with abcesses.

Sea Duck liners - PCB's - 48 samples looking at PCB's and other compounds.

Lissa Riley - Clemson University
Majority of the work being conducted involved the use of fatty acids for the identification of fungal plant pathogens.

Second project - looking at the levels of fludioxinil on peaches after they have gone through a processing line - fludioxinil is being used for the control of brown rot during shipping.

Doing a lot of analysis related to plant products such as phenolics in fig leaves, essential oil analysis in geranium, and fungicides in peach roots following the injection of fungicide into the trunk.

Business Meeting:
Field extraction apparatus - everyone in the group may not want to build this. Discussed the possibility of not meeting next year, and agreed that this was probably the best thing to do.

Scott Senseman will be out of the country over the next year.

SDC-316 is a new possible project that is looking at chemical sterols .

Meet summer 2007, possibly in Puerto Rico, to do the termination report, field extraction set-up (pesticide analysis of different compounds).

Don't see a common enough theme to have a continuation of a project for 5 years from now -Need to do something else new and different if we develop a new project after the current project.

Adjourned.
