Activity Report
Further research was done on the deferred rule concerning blowing of different varieties of Poa pratensis. A Rule proposal was submitted for the Ordinary Meeting.
A "universal species list", including the 130 most frequently-encountered crops and weeds, was prepared, based on information from an ISTA-wide survey. This will be available for discussion at the Ordinary Meeting.
A very successful purity workshop was held in conjunction with the AOSA/SCST meetings in Seattle, Washington, on June 11-12, 2003
Procedures providing for the testing of seed mixtures were prepared for discussion at the 2004 Ordinary Meeting.
Future Aims
- Continue to work on procedures for sampling and analysis of mixtures, in cooperation with the Germination, Statistics and the Bulking and Sampling Committees.
- Continue with the on-going task of redoing the PSD handbook.
- Do a collaborative study to determine if pure seed of Poa spp. determined by use of the blower is affected by sample size.
- Compare the ISTA and AOSA calibration samples.
- Prepare a basic outline to be followed for all purity workshops. This would eliminate the need to "re-invent the wheel" for each workshop. |
