Field trials done with Terrazole® 4EC (4 lb. active ingredient/gal.) have demonstrated that this product can be tank mixed with Terraclor® 2E or Rovral® 4F to provide broad spectrum seedling disease control. Mode of action studies indicate that soil applied etridiazole is readily picked up by germinating cotton seedlings and moves systemically throughout the roots, stems and cotyledons. Plant metabolism studies in cotton show that in mature plants etridiazole is degraded to naturally occurring compounds.
