so there seems to be some confusion about registration and i would
really like to know, if usage is still allowed
so to cathy brunetti (if she is reading this):
may i conclude from the data above, that 2,4-d is used on one
fourth of the total american wheat area and is NOT registered ??
the chem-usage-file dates from may 99...
