Ok to spray dormant oil in Fall?

General Fruit Growing

So, where I live it’s 19-22 degrees Celcius during the day and the leaves are beginning to fall off my peach trees.

I didn’t spray dormant oil on my peach trees in the Spring before they woke up because I was afraid it would interfere with my peach leaf curl spray.

I had a lot of borer damage this year so I was wondering if I could spray the dormant oil now? Will dormant oil kill borer larvae or eggs? Is it not recommended to spray oil because it’s not completely dormant yet?

TIA

I don’t know how well it works with borer issues, but you can spray with a heavy dormant oil now, and should.

Scott suggests neem oil is very affective in the control of peach tree borers. Regular oil will only reach ones not in the wood and caterpillars are not generally treated with it anyway. What does the label say? I think that should be your first point of reference.

I believe @scottfsmith use of neem is not for spraying. He applied neem directly to the trunk if peach trees. I can’t recall when he applies neem.

You mean he paints it and doesn’t spray it?

He paints/smears it on the trunk I believe

You might also plant garlic now around the trunks of peach to dissuade borer action. Has worked well for me so far on my three peach trees

So you wait for more leaves to fall before spraying?

I mix the dormant oil and copper together.

I use a chemical called Ziram so I was concerned about mixing it with something else

Garlic repels everything.

I want to see garlics repel plum curculios, oriental fruit moths and coddling moths. When that happens, I will be a believer.

Are there Peach Tree Borers is this area,Dennis?

Yes, I lost an apricot tree here during my first year in my new home. Also had attacks on one of my cherry trees. My neighbor’s Frost peach has not had them though so I never understood why. But they are quick to kill apricots

I paint the trunk of my fruit trees white withe interior latex/ speckling paste. Also helps to prevent cracking in the winter.
