Test Program Review

Print Version

The JCIBPC granted eight test programs for the 2014 - 2015 marketing year during its annual meeting.  A summary of committee actions follows. The summary contains information about the type of test program granted, a short description of the material or system being tested, the name of the company sponsoring the program, the number of years in a test program, the size of the test program, any special requirements for the test program and some key physical properties of the material or the nature of the system being tested. All tests are to be conducted in all four regions of the cotton belt unless an exception to this provision is noted.
