Home Orchard Spray Program
Posted: Wed Feb 29, 2012 4:44 pm
What a battle it is to work out a preventive spray program for a fruit orchard. My biggest battle is fireblight and fruit rot because it is so humid down here.
At least here in the US, the number chemicals we have for control of the orchard health is getting pretty small but what we have is still good.
I noticed the effective rating for copper and lime-sulfer is very low which I figure means it is limited to use as a dormant spray to keep from wasting money.
Timing seems to be everything.
I did my last spray with oil and copper today on the latter season apples. My summer apples have bloomed with this warm winter but took a big hit by a hard freeze.
What is everybody else using for a spray program?
