24 lut 2019 · Discover how to deal with fungal and bacterial canker infections on trees, which can spread to whole sections, with help from BBC Gardeners' World Magazine.
Use a solution of one part of household bleach and nine parts of water. Then paint the pruning wounds with a copper fungicide such as Bordeaux mixture to prevent re-infection. Do not use pruning compounds—they do not protect the tree from the disease. Copper fungicides are water-soluble.
2 kwi 2023 · Control brown rot and remove any brown-rotted fruit from trees before cankers form on the twigs. Annual brown rot cankers may serve as infection sites for Cytospora. Control the Oriental fruit moth and peach tree borer.
29 wrz 2022 · Some essential oils and plant extracts have the potential to be formulated into organic fungicides to prevent stem canker in durian trees by inhibiting the growth of P. palmivora as tested in vitro. A recent study shows that the vapour of clove and citronella oils can slow down P. palmivora growth in vitro ( Istianto and Emilda, 2021 ).
3 maj 2024 · This work proposes essential oils (EOs) as viable alternatives for fruit sanitization. EOs from Cymbopogon species were evaluated as to their antibacterial activity, their effect on the bacterial membrane, and their ability to sanitize citrus fruit.
To manage the disease, reduce stress on trees, use resistant plants, remove infected limbs, clean wounds and prune properly. Cytospora canker is caused by various species of the fungus Cytospora (sexual genera of Valsa and Leucostoma).
Cytospora Canker of Fruit Trees: Leucocytospora cincta; L. leucostoma Cytospora canker (or Valsa canker) is a very destructive peach disease that causes reduced yields and even death of trees. Cankers occurring on large scaffold branches, in the main crotches, or on the trunk may enlarge to girdle and kill the portion of the tree above that point.
