20.01- Names of all personnel conducting specific research functions
20.02- Amendments and deviations from protocol and standard operating procedures
20.03- Test site information
20.04- Plot maps
20.05 - Test substance receipt, use and container/substance disposition records

20.07- Data regarding calibration and use of application equipment
20.08- Treatment application data
20.09- Crop maintenance pesticides and cultural practices, test plot history, and soil information. (Reporting soil information from typical farm service soil analysis labs, or past history for the farm, or from official documents, such as the SCS Soil Survey for the test plot area is adequate for this study. The nature of this study is such that soil characteristics do not need to be determined under GLP standards.)
20.10- Residue sample identification, collection, storage conditions and handling (Weight measurements are considered estimates for the samples collected from field or processing trials, and the scales/balances used for this purpose do not need to be maintained in strict adherence to GLP.)
20.11- Residue sample shipping information
20.12- Description of crop destruction, or explanation for lack of destruction
20.13- Daily Meteorological/Irrigation records ()--required from the date of planting or transplanting of annual crops or for a minimum of one month prior to the first application onto perennial crops, until last residue sample collection. These records do not need to be determined under GLP standards. If transplants are used for an IR-4 trial but no test substance applications are made prior to the transplanting, then temperature/humidity records are NOT required for the period prior to transplanting.
20.14- Pass times (if applicable) and other data to confirm amount of material applied to plots
20.15- Equipment maintenance records with indication of routine vs. non-routine nature of maintenance
20.16- Other applicable data requested in the IR-4 Field Data Book necessary for confirmation that the study was conducted in accordance with the protocol.

Fiber Sample: At 15 (±1) days after the last application, harvest 12 hemp plants from separate areas of each plot. Begin with the untreated plot first, and then harvest the treated plot. Each sample should be collected during a separate run through the entire plot. The harvested plant should be left to dry in the plot to a moisture content of less than 15%. Document the estimation of moisture content in the Field Data Book. If necessary, the harvested plants may be moved to a protected area for drying. Once the plants have sufficiently dried, then fiber samples may be collected. Each sample should weigh a minimum of 2 lb (but preferably not more than 4 lb). Select 12 plants and separate them into 3 groups of 4 plants each. Divide each plant into 3 approximately equal lengths. Take top portions from one group, middle portions from the second group, and bottom portions from the third group, to ensure that parts of all 12 plants are included in each sample.
