Combinations
of vegadex-Randox
l
Orsenigo (2)' reported in 1959 that tank mix combinations of Vegade.xand
Randox(CDAA) showed promise for use on celery. Ratios
of 1:1 .. 3:2, and 2:3 (totaling 5 pounds per acre) were more effective,
1n weed control, especially of gras/ses than a 5 pound per
acre a.pplleatton of either herbicide alone. Sweet (3) recently
reported that"acombination or Randox and. vegadex broadens the
spectrum of activity with indications of greater crop selectivity.
Spinach, tomatoes, broccoli and carrots were included in these
trials. Ratios of 1:1 totaling 4 to 6 pounds per acre looked most
promislng.
SUl1UJILl ry
Continued field experience by the grower is opening many avenues
of successful uses for Vegadex for control of weeds in vegetable
crops. Depending on aqpptabilltyand SUitability, the applications
of Vegadex will include sprays and granules both pre- and postemergent
to the crop.
