FOlks, using any pesticide
under the minimum label rate is not only illegal, but vastly hastens the
development of resistance in the organisum you are trying to control. This is
true for both organic and convential chemicals, The manufacturers of the
pesticide normally use the lowest effective rate as the minimum labeled rate.
We use Orbit, Pristine, Bravo
(can only be used before shuck split but controls blackknot and peach leaf curl
as well) which are very effective reduced risk chemicals to control brown
rot in stone fruit.
TO calculate the amount of chemical to use, look at the
label for gallons needed per acre (normally ~100 gallons) and how much
chemical per 100 gal and divide by how many gallons you are making. For example
if the lable calls for 1 pt per 100 gallons, and you are making 25 gallons, use
4oz of chemical. If you are using dry chemicals you have to wieght them using a
scale (small postal scales are cheap).
I do not understand why Copper is considered "organic"
or "sustainable". Using copper is adding poisonous heavy metals to your soil,
and while even the worst of the chemical pesticides will break down over time,
Copper is forever.

Indar is much more affective than Captan for the control of blossum blight and brown rot. Here in humid southeastern NY, once I have the pathogen under control I can often control BR with a single application of Indar a month before the first peaches ripen. With plums a seperate application may be necessary a month before the particular variety ripens. In very wet seasons an extra application or 2 may be necessary, but I never have to spray within a month of harvest anything besides cherries. I am interested in the efficacy of Pristine. Has anyone out there tried reduced applications of that substance to control BR in their orchards? -------------- next part --------------
