1. Coppers are effective
but…
•
•
•
•
•
you need very good coverage
do not use liquid formulations
do not use wetting agents
never add anything to Copper sprays
It is better to use several Copper sprays at lower rates than
one or two at higher rates
• Always apply in good drying conditions
• Only apply when the fruit is dry
Tim Torr
Streptomycin
•
•
•
•
•
lasts longer than we expected
has very persistent residues
is not a cure
does not work as an injection on Kiwifruit
must NOT be used “off label”
Tim Torr
Biological control agents
(BCA’s)
• intermittent in their level of control at best
• do not work well at cool temperatures
• may be synergistic when used in a program
with Coppers
• can be very useful to provide protection over
flowering
Tim Torr
Elicitors
•
•
•
•
need to be applied well before the pathogen
have a metabolic cost
have been associated with small fruit
some are better than others (some don’t work)
Tim Torr
2. Don’t over react
• don’t anticipate how situations might play
out, it may not be as bad as you think
Tim Torr
3. You can make a difference
Often the things that you do on the
orchard determine the outcome … even
