A long, cool spring here in Southern California allowed quite a few FB
strikes, three days in the low to mid-90's stopped it in its tracks.
Formerly limp shoots with sticky ooze and now crispy and dry, and pruned
stumps do not get re-infection. That's all I'll see of it until next
spring, weeks o
For the first year ever I havent seen any FB here is western Illinois, could it

Hi Art
If a flower opened at 7am on Friday May 19, and you had sprayed strep
just before that, then that flower would not be protected.Using Sanford

Hi!
Once a flower opens, it needs to get contaminated by an insect and then the
population needs to multiply to 100,000 before wetting, otherwise the infection
is a dud.
That takes 36 hrs when the conditions are perfect for the bacteria (28°C,
82°F), and considerably longer when the temperatur
Thanks, I was more wondering how close to try and get to the infection period
due sometime tomorrow morning. We are mostly
in bloom with some varieties nearly complete petal fall and others (honeycrisp)
at full bloom. There are very few flowers still to open and I expect that this

Hi all,
My two cents:
Although streptomycin is degraded by light, this doesn’t really matter: For two
to four days, the antibiotic keeps bacterial population at low levels on
sprayed flowers.
Once it’s degraded, the flower is also 2 to 4 days older and there is simply
not enough time left for
Step can generally last for 2-4 days without rain. As it is degradable by sun
light, it lasts longer in over cast days than in sunny days. Rain can wash some
