Like 2oz to a 1000ml bottle. On the root aphids I felt the ammonia worked better, same, about 2oz per 1000ml spray bottle.
I would cut a piece of covered root and do it on a white plate or bowl inside under a light and with magnification so you can see well.
It is just delaying the root mass’s development. Sometimes you can find rootstock with very minimal root growth. I normally leave rootstock in a media in bins and graft them fairly quickly.
However that bunch got a week and a half delay before I got them heeled in. A lot of the G.214’s did not have big roots on them at the time. This particular batch being regrades.
Of course my M111 and P.2 were regrades and only about 50% of them died off.
I’m starting to think there is something about CC that is particularly susceptible to WAA. I just found some on the one I grafted this spring. I had 6 container apples close together on my deck, all with the same soil I mixed up, all Geneva’s (5 G.214 and 1 G.41) and only the CC showed WAA.
Regardless if the nodules on the roots are WAA or root knot nematode, how concerned should I be about eggs spreading to other containers in their smashed together winterized state? I just posted in another thread, but do you think neem soil drench will adequately address the issue prior to winterizing?
Neem oil probably will not do it. If you can find some Black(Indian) mustard plants; you can chop it up and mix it in new soil to repot your CC. The pungent Mustard volatiles will work as a fumigant.
Barerooted the tree and hosed it off. By your extensive apple experience, does this really look like root knot nematode over damage from WAA? Does it matter for management if it’s one over the other? I didn’t manage to remember to do that vinegar test to see if the white fluffy stuff wiggled. I’ll seed the things you recommended in the container next spring.
Root knot nematodes. As well as the Black Mustards; Plant French Marigolds. They provide a target for nematodes and trap them. Putting a dent in nematode populations. Be sure to use Tagetes Patula species only. As other Marigold do not have the effect to curb nematodes.
On black mustards I see folks plant them in between tree rows and mow the cuttings right around the trees. Then rake them in circles on the trees.
Thank you for the advice. I’ll get them seeded around everything in spring. I’m concerned I used the shovel to dig another apple back in October after it touched this one. It’s been quite the whirlwind of a first year of disease lessons!
If anyone in the area would like my Crimsoncrisp on G.214 from Cummins (received this year and pictures of roots above), after reading more on MD extension, I’ve decided that the fireblight risk doesn’t work here since I’m not willing to spray for it. Bummer because the apples (tasted at U pick at start of this thread) are really, really good and otherwise it should be an easy tree. I sprayed it a few times with regalia and it had almost no CAR and only a little ALB at the end of the season. Regarding the root knot nematodes- I aggressively hosed off the roots and did a dilute neem spray and then repotted it in a new, clean root pouch with new soil. I headed it back in March to encourage branching and then again in summer as I was intending to keep it small. Message me if you would like it, free for pick up to a good home!
If you like the apple I wouldn’t be so hasty to get rid of it. I have CC also. Some people have problems with FB while others never really see much of it no matter what variety it is. For me rots and insects are a much greater concern.
Thanks for the vote of confidence. I’ve been reading too much and got concerned. Especially bc my trees are all very close. I’ve learned to let go and be fluid this year, though you can certainly argue sometimes too quickly.
The main issue with Crimson Crisp I would have is it needs more care for bitter pit. But many high flavor apples are that way.
