Number of pages: 105
Subjects: Herbicides -- Toxicology.
Genres: nonfiction
First sentence: Herbicides, as their use continues to mount, are an increasing potential pollutant of the biosphere.
Description: Fiddleneck, a species normally susceptible to bromoxynil, has been reported to be somewhat resistant if bromoxynil application is accompanied by cold temperatures.  The mode of action of bromoxynil on susceptible species and the mechanism of degradation have not previously been completely elucidated.
	Research was undertaken to a) determine the effect of cold temperature on bromoxynil phytotoxicity in fiddleneck and b) further elucidate the reason(s) for selectivity and the mode of action of bromoxynil in wheat and fiddleneck.
