Notes:

This is a picture of what appears to be blister like bumps on the leaves of one of my pecan trees. Is this a disease or fungus? Please advise. Any help would be greatly appreciated.

    Any south Ga pecan farmer will tell you, the trees are sprayed monthly year-round to control such critters. They are sprayed from the ground, to reach the underside of the leaves, with a truck-based large sprayer and chemicals specific to the time of year. BTW: if you’ve parked your vehicle under a pecan tree & it came away with a thick gummy substance, it’s worm droppings and will run paint if not removed quickly. Rule in south Ga, don’t park under a pecan tree.

    This is the first year that our tree had these so-called galls.The smaller tree has none but the big tree is covered. This is in Middle/West Tennessee.

    Problem Info Green to yellow-green galls appear on the leaves, shoots, and nuts. These galls, which range in size from 1/8 to 1 inch in diameter, split open in the late spring. Shoots with galls on them may be weak and dying. When the galls are cut open, tiny, soft-bodied insects may be seen inside. Analysis Phylloxera species These insects, closely related to aphids, are common pests of pecan and hickory trees. Phylloxera eggs, laid in the fall, survive the winter on branches and twigs. The eggs hatch when leaf buds open in the spring. The emerging insects, called stem mothers, feed on new spring growth by sucking the plant sap. They inject a substance into the plant while feeding that causes the plant tissue to swell, forming galls. Eventually the galls envelop the feeding insects. After the stem mothers mature, they lay their eggs and die. When the second generation of winged insects matures, in late May or early June, the galls split open, releasing them. Although these pests are present throughout the summer, they are most damaging to new spring growth. Solution Advice Once galls have formed, the insects cannot be killed. Appy an insecticide that”s labeled for these pests, following label directions.

    There is a horticultural oil you can spray your tree with before it buds in the spring. You have to catch it before it buds apparently. DonÕt know the name of the oil.

  • Jan Unregistered says:

    Since someone above said the pustules open up and release aphoid-like insects, would it be advisable to remove the leaves that contain such growth, before they hatch? Would that shock and or kill the tree? On my 25+ year old tree I canÕt reach to top branches, however! (My mother suggested talking to the tree and telling it if it doesnÕt shape up and produce nuts again, IÕd chop it down for firewood. . ). Any practical advice out there??

    I’ve got gall type spots on my tree. The tree almost died. I cut it back last year and when the branches were filling with green leaves this spring I noticed the beads on the leaves…like pearls..on many branches. I don’t know how to treat this.

    I have had this on my 1 pecan tree for 10 years now. Don’t know if there is a connection, but the pecans the tree produces are no good…black and rotten on the inside. On a recent trip through south Alabama where there are many pecan growers and businesses one of the owners told me to add a bag of 13-13-13 and supplement it with minerals (including zinc)around the perimeter of the tree fanning out to below the edge of the longest branches (drip line). I dig holes and fill them with the fertilizer and cover them back up. I don’t know how well it will work yet but I’ve been told that if the tree is healthier it can fight off the galls better. I’ll continue to do this until I am able to report any improvement.

  • William Unregistered says:

    Solutions While chemical and botanic-based insecticides are available for home use, they are not recommended. Once galls have formed, they cannot be cured or removed, and applying insecticides is neither cost effective nor helpful. Because you will likely not see a subsequent infestation the following year, you should give your tree the time to heal itself. Maintain excellent care of your trees so they can recover from pests. Fertilize your trees once annually with four pounds of 10-10-10 fertilizer per inch of trunk diameter, suggests the North Carolina State University Cooperative Extension.

    I found them on my 3yr old tree. I have cabbage in planters under and noticed strange material on the leaves, looked up and found the pods on the leaves of the tree the black spots on the cabbage was droppings. As I pulled the pods off I noticed a white bug fly or jump off the leaves. First time I have seen this. Central Ark.

    First time seeing this on my trees. It’s terrible looking. This makes a sparse looking tree; the foliage is stunted and what’s there has all of these goose bumps over them. Considering cutting it down.

    I have these on my pecan trees in the panhandle of Texas. I have opened some of them up and there is a tiny larvae inside, about 1/8″ long and about as big around as a straight pen. I will spray my trees next year in early spring with an insecticide that is suggested by my local nursery. They don’t seem to be harming my trees too much, except the fact that I notice them on some of the leaves.

    I put a once a-year-year insecticidal drench w/merit,around my trees (i have three mature trees).I put the first qt. in Fed. the next one in late March just when bud started ti show, the next when the leaves & bloom was on. now this is a once a year drench,i have more knots that the bugs hatch out of than i did before. So good luck with what ever you try.

    I seem to have lost any production on my trees in the past 3 years. 2011 & 2012 so many I couldn’t pick them all up. Now no production. Has anyone found a way to rid the trees and how early do you start the treatment?

    I also have these on my pecan tree leaves. I’m in Canton Ga., just north of Atlanta. They started early on as small round green bumps, a little wider than an English pea, with one per leaf early on. Later this summer (late June and early July) on the underside of the leaf, these became fuller, more rounded and split open on the end, similar to the way a pecan hull or covering splits open when it’s time for the nut to fall out. The texture becomes woody (like the outer covering the pecans drop out of), only much smaller.)I have never seen what dropped out of them, they are all empty. Now (early August), I have this white spittle like substance near the base of where the leaf stems join together on the limbs. I’m too am stumped.

    Metro Atlanta here. Same situation. Evey year around May. From the lowest branches to as far as I can see. Other websites say, “They can be created by fungi, bacteria, mites or nematodes, but most are caused by insects. Surprisingly, they don’t seem to have much impact on the plants. Leaves with galls apparently continue to photosynthesize effectively, while providing shelter for the small larvae.” “The pecan leaf phylloxera, a type of aphidlike insect, feeds almost exclusively on the leaves of pecan trees. Small infestations may result in nothing more than minor yellowing or insignificant leaf drop, while major infestations can threaten the health of entire limbs. If the phylloxera attack young shoots and nuts, the tree might not produce nuts both in the current and following year.” “Fortunately, this looks worse than what it is, and it rarely causes serious problems for the pecan tree. Once the galls appear, it is too late to control pecan phylloxera for the season. However, in most cases it is not necessary to be concerned, since they usually do not cause enough damage to pecan trees to warrant an insecticide application. Spraying large backyard trees is usually not practical in any case.”

    I have something like this on my pecan tree too. I’m in Arkansas. They almost look like some kind of cacoon. But I’ve noticed them on other parts of the tree too. On leaves and on stems, and some where pecans are supposed to grow. And some of them appear to have tiny leaves growing from them. I’ve never seen this before. We do not use chemicals around our yard. But earlier this year the city came out and butchered one side of the trees, cutting all the limbs back to keep them off power lines. I am stumped.

  • Jeffrey Clower Green Thumb says:

    We have the same thing on our pecan tree leaves. The Extension Service did not really know for sure, but said it is probably galls. The galls are caused as a result of the feeding of an insect called pecan phylloxera in April. They split open in May and early June releasing aphid-like insects. The galls then dry causing twig dieback and leaf drop. Can cause the loss of pecan crop. They damage tree appearance but rarely kill tree. Most effective control is in spring when eggs hatch and small insects crawl to buds. One or two sprays of Provado 1.6F, Warrior 2.56 and Lorsban 4E…But how do you spray an entire tree???? We haven’t found a way yet.

    Probably galls that are caused by insects or chemicals that irritate the leaf surface.
