. Begin
applications within one week of transplanting or emergence. Make up to six
weekly, consecutive applications.
4 hr Begin applications shortly after emergence or transplanting and continue on
2- to 7-day intervals if conditions are conducive to disease development. For
improved suppression of bacterial spot and speck, tank mix or rotate with labeled
copper-based bactericides.

See label. Rates vary depending on the formulation. Make first application 7-10
days after transplanting. Carefully examine field for disease to deter mine need for
additional applications. If disease is present, make additional applications at 5-day
intervals. Applying mancozeb with copper significantly enhances bacterial spot
control. Do not spray copper when temperatures are above 90°F.

Apply preventatively on a 5- to 10-day schedule. For best disease control, Leap
should be used in tank mix or rotation with other registered pathogen control products,
especially if disease is already observed in the crop.
Use 6 oz of product per acre in no less than 30 gallons of water per acre. NOTE:
May only be used to manage bacterial spot in Florida, Georgia, North Carolina,
and South Carolina (Section 2(ee)).

needed depending on disease severity. Use the higher rates when conditions favor
disease. Do not spray copper when temperatures are above 90°F.

Some pathogen strains are resistant to streptomycin sulfate.

Limit of 55.3 fl oz per acre per season. Make no more than two consecutive applications
before rotating to another effective fungicide with a different mode of action.
The addition of non-ionic based surfactant or oil concentrate is recommended.
Apply preventatively or when conditions are favorable for disease development.
Repeat on a 7- to 14-day interval as necessary if conditions are favorable for
disease development.
Begin applications prior to disease development and continue throughout the
season on a 7- to 14-day interval. For resistance management, do not apply more
than two consecutive applications before switching to a non-Group 7 fungicide.
See labels. Rates vary depending on the formulation. Begin applications when
conditions first favor disease development and repeat at 3- to 10-day intervals if
needed depending on disease severity. Use the higher rates when conditions favor
disease. Do not spray copper when temperatures are above 90 °F.
