How do you treat a diseased plum tree?
Apply the fungicide when the trees are dormant in the spring – when there are no green buds, leaves or flowers present. Then, spray again when the flower buds color up. The fungicide is to prevent more problems; it cannot cure it. Use a fungicide that has an active ingredient of chlorothalonil or thiophanate-methyl.
What is stem pitting?
Mandarin stem-pitting is caused by a strain of Citrus tristeza virus (CTV), which belongs to the Closterovirus genus. There are many different strains of CTV, each producing a different suite of symptoms on different citrus cultivars and rootstocks. The mandarin stem-pitting strain is particularly severe on mandarins.
What is killing my plum tree?
Plum aphids are another common pest found on plum trees. Aptly names, as plum leaves are the pests' favorite food. These aphids are green, yellow or brown and under ½ inch (1.25 cm.) ... The curled leaves then do not photosynthesize properly, which stunts the tree and/or fruit and, in severe cases, will kill the tree.
What conditions do plum trees like?
Plums grow best in a sunny spot in well-drained, fertile soil. Most trees in the plum family come in sizes to suit all gardens. If you choose your tree carefully you can train it into your preferred shape – as a standard or fan. Smaller trees, grown on semi-dwarfing rootstock are easier to maintain.
What is growing on my plum tree?
Trees in the genus Prunus, which includes plum, are susceptible to a fungal disease called black knot. ... The fungus overwinters in the knots on the stem, beginning growth again in the spring and producing more spores to start the disease cycle all over again.
How is the citrus tristeza virus spread?
Citrus tristeza virus (CTV) is transmitted by several aphid species in a semi-persistent manner with Toxoptera citricida, the brown citrus aphid (BrCA), being the most efficient. As yet, the molecular interactions between the virus and its aphid vectors have not been determined.
Why is my cherry plum tree dying?
A number of fungal diseases may also contribute to lost leaves on a plum tree, and these include: Armillaria root and crown rot, Phytophthora, and Verticillium wilt. Foliar diseases, such as plum leaf spot, may be the culprit too. ... Pests – Spider mites or an aphid infestation may also result in plum tree leaf drop.
What fungus attacks plum trees?
Black knot is a widespread fungal disease that attacks plum and cherry trees, both fruiting and ornamental. The fungus, Apiosporina morbosa, (also identified as Dibotryon morbosum and Plowrightia morbsum), singles out trees of the genus prunus, which includes peach, apricot, and chokecherry.
What is killing my fruit trees?
If fruit trees have a lot of sunlight beating down on the trunks and limbs without much protection from the canopy, they can be sunburned, borers can enter the tree and cause the tree to begin dying, one branch at a time. ... Eventually the tree dies from damage created by borers in a couple of seasons.
