I was just spraying all the fruit trees and vines in my yard this morning
and was wondering if anyone knows why the instructions and orchard owners
say it's best to spray before rain. Doesn't that defeat the purpose by
washing it all away?

If the spray your using is a protectant like Captan ,Mancozeb, Sulfur
or bordeaux mixture the stuff needs to be there BEFORE it rains. It
prevents the fungus from starting. Mancozeb, for example, will not
kill an infection it only stops new ones so it needs to be on the leaf
prior to infection. It also spreads on the plant with rain. If your
using a systemic ( Nova) or Stroby ( Abound) there is "kick back"
depending on the stuff being used. BUT, It's ALWAYS better to have the
spray on the leaves before it rains no matter what.

Don't know if this changes anything but here's what's in it:
Phosalone 4%
Ferbam 15%

Theses are the ingredients in "Wilson's Fruit Tree Spray" I'm told by
orchard owners in my area that this stuff is considered extremely benign
compared to what they use so I wasn't worried when I bought it.
Can anyone suggest something else that will work. If I don't spray, my
"entire" crop will end up in the trash.
I live in an area where everyone has at least one apple tree in their yard
and we're completely surrounded by orchard so I have no choice but to spray
if I want to harvest something.

Louise - In the States there is a government agricultural office in every
county and they are very good about providing information about spraying
schedules for apples as well as grapes and all other fruit and vegetables.
Perhaps there is a similar office in your area of Quebec. If not why not
spray what the commercial orchards spray?

I emptied my 12 volt sprayer of broadleaf weedkiller, then put in Mancozeb. I
sprayed on the ground until I was sure the yellow Manc was coming out, then
proceeded to spray my grape vines. Damned if the first vine or two didn't get
damaged. I'm dumbfounded that there was enough weedkiller residue left in
there to do this. Hopefully, they'll recover. So, I pass my experience
along. A word to the wise.

Ken,

Thanks for the reminder. I'm in exactly the same boat, with my 2nd shot
of Mancozeb in a few days. However, after the weedkiller I rinsed the
sprayer several times & sprayed it thru too. It's been airing out for a
few days now to rid the tank of the odor, which I figure can't be good
for vines either. Maybe I should run some soapy water thru too? What
was the weedkiller? 2,4-D?

Triple rinse with water, including the hose. That's the law in the USA.

That's why we use two different sprayers: one for herbicides, and one for
everything else (fungicides, dormant oil spray, insecticides, etc.).

Hi Bill,
I've already got a good schedule but the question is what should I use that
won't be too dangerous (whatever that means) We don't have access to what
the orchard use and none of the orchard owners are will to give up any of
their info or sprays.

If there are orchards in your area there must be stores where they buy their
spraying chemicals. These chemicals come in large packages for use in a
commercial orchard and there's some expense involved. But if you keep the
packages tightly sealed and in a dry, cool area they should retain their
activity for more than a year. In my area several of us who have hobby
vineyards split large orders of chemicals, corks, special yeasts. Perhaps
you could do the same.

I have no idea what is recommended for trees and vines in your area but here
in the Kansas City area I spray Mancozeb & Nova. Closer to harvest I switch
to Captan & Nova. I add Thiodan to the spray for my fruit trees. Also
included is Sevin or Imidan for insects as needed. I have no problems with
disease in the vineyard nor the orchard.

wEEZ,

Mancozeb is available at any garden center in the states. It is safe
and does a good job on ALOT of different fungus.
