PROGRESS IN USE OF HERBICIDES ON HIGHWAYS
THE RESULTS OF CONTINUING WORK WITH AMINO TRIAZOLE INDICATE THAT IT SHOULD BE A STANDARD MATERIAL FOR USE IN WEED AND BRUSH CONTROL. THIS MATERIAL IS EFFECTIVE ON SEVERAL PLANTS THAT ARE RESISTANT TO THE PHENOXY MATERIALS. FOR EXAMPLE, POISON IVY IS PARTICULARLY SUSCEPTIBLE TO THIS MATERIAL, AND A TOTAL KILL MAY BE EXPECTED WITH ONE TREATMENT. AMINO TRIAZOLE IS READILY TAKEN IN BY THE AERIAL PARTS OF PLANTS AND TRANSLOCATES RAPIDLY TO THE GROWING POINTS. CHLOROPHYL SYNTHESIS OF SUSCEPTIBLE PLANTS IS UPSET AFTER ABSORPTION OF THE CHEMICAL. SOME PLANTS, SUCH AS POISON IVY, SHOW A RAPID AND COMPLETE DESSICATION SOON AFTER TREATMENT. OTHER PLANTS, SUCH AS ASH, SHOW A CHLOROTIC CONDITION FOR AS LONG AS A YEAR FOLLOWING SPRAYING, WITH DEATH RESULTING THE FOLLOWING FALL OR WINTER. THE SELECTIVITY OF AMINO TRIAZOLE IS OF A DIFFERENT ORDER FROM THAT OF THE PHENOXY MATERIALS. GRASSES ARE GENERALLY SUSCEPTIBLE. AMINO TRIAZOLE IS APPLIED AS A FOLIAGE SPRAY WHILE PLANTS ARE IN LEAF, USING FROM 2 TO 12 POUNDS PER 100 GALLONS OF WATER AND APPLYING TO WET THE FOLIAGE THOROUGHLY. REPORTS INDICATE THE FOLLOWING PLANTS TO BE SUSCEPTIBLE TO AMINO TRIAZOLE AT VARIOUS RATES: WHITE ASH, WILD BLACK CHERRY, HICKORY (VARIOUS SPECIES), MILKWEED, OAK (VARIOUS SPECIES), POISON IVY, POSON OAK, PRICKY ASH, (COMMON), QUACKGRASS, WESTERN SNOWBERRY, AND CANADA THISTLE. /AUTHOR/
