Spraying apple trees

6 posts in this topic

I have 9 apple trees in the back yard. I've heard so many different things I don't know what to do. I've been told to spray them with insectacide when the blossom, before they blossom, after they blossom, middle of the summer, and never.

These trees really crank out the apples. Last fall I had to pick some apples early cuz the trees were so bent over from the weight, but a lot of apples had bugs and worms.

So I toss the question out to yous guys, when should I spray them and what should I spray them with????

I checked on this a while back and they recommend whey to much for me but go to the Arbor Day site and there's a fruit tree schedule,I got mine down to no bugs,scale or rust with 3 sprays one as I see blossems start one after most all fall and one when apples are pea sized seems to work

Spraying for fungal disorders (leaf spot, apple scab, rusts) is done early on during leaf growth. Usually spray when leafs are half out and spray again 7-10 days later. Some products recommend multiple treatments, but usually 2 is fine unless you know youre trees get it particularly bad.

If you're talking about insects and protecting fruit then that is done during fruit development. I've never done that type of spraying because of the food involved, I didn't have that certification.

You need to identify what you're trying to control and then pick a course of action.

We have spayed our 6 apple trees in the past but last year we hung a baby food jar in each tree half full of vinegar and while I can't say we had totally bug free apples it really kept the bugs down. It worked.

Really dumb question, but does vinager evaporate?? Meaning, do you have to go re-fill from time to time?

Yes about once every two to three weeks. You will see lots of moths and bugs in the jars.

    • Think im gonna try good old grass clippings since they seem to replenish themselves very rapidly
    • My good buddy from back in SD does fantasy and we have another group we are apart of and he ended up tied for 5th overall last tourney. After day 3 he was in 3rd with the possibility to win it. So close to getting that $2500 basspro card
    • After the cold snap, temps on Trout were back down in the high 40s. Back around 53 now, and should keep warming if the forecast holds. Fish have already moved shallow, bedmaking and piscine lovemaking will follow soon for the brown ones. I am hitting Leech tomorrow...will be interesting to see what water temps are in the protected parts of the bays.
    • Here's some useful information: go shallow, and chuck a swim jig with a paddle tail trailer and set the hook til your arms fall off. Better?
    •   If you like to tinker with guns, you can get a surplus Saiga for a couple hundred bucks.  All sorts of accessories available for these, and they can also be converted to 12 gauge if that's your preference.          
    • I was out last night on a local lake and was surprised to see the water temp down to 57.  Caught a couple cookie cutter fish, but not the big ones I was looking for. Fished a lot of weeds in the 6-9ft range, but not a lot going on there. The biggest one was still shallow in some reeds, so not sure if we are still in the spawn/post spawn stage.     Whats everyone else seeing out there for a bite and fishing conditions. Big weekend coming up, Good luck!! 
    • Maxine_Partain, Welcome to the forum.  There seem to be a lot of folks from Canada joining up in the last half a year which is nice. The sad thing is they all seem to make about 3 posts on the same day they joined and then they never come back which is sad. Hopefully you will keep posting.

    • hi and welcome to HSO. I think you mean double hung not double pane. if you have moisture between the panes you have a seal failure. depending on the brand you might be able to just replace the glass. If you have lots of rot you may need to do a complete replacement. Best to have a window person pop by and check out the situation.
