Main Avocado Tree Diseases
As you grow your young avocado tree there are many diseases you should be on the lookout for as they can stunt the growth of your tree or spoil the development and taste of your tree or spoil the development and taste of your avocados.
Avocado trees infected with sunblotch often show stunting, discolored twigs, and fruit. Even in situations where the tree doesn’t show a lot of symptoms, it is not unusual for the annual yield to drop dramatically.
Treatment Options: Although there is no known cure for sunblotch, tree owners can treat it by continuing to practice good pruning hygiene. Be sure to sanitize your pruning tools with bleach if they’ve been used on a sunblotch-infected area. If possible, use separate and uncontaminated tools for healthy trees.
Trees infected with cankers often take a sunken appearance with sap and gum often dripping from the exposed areas. The effect of cankers can range from merely being unsightly if just the branches and trees are affected, or potentially killing your tree when cankers develop in the trunk.
Treatment Options: Pruning and removing dead and dying branches below the area that’s been infected is a good start along with being careful to seal the pruning cuts. To address the bacteria causing the cankers, fungicides are often highly recommended.
Fruit rot happens as a result of unsanitary conditions and sometimes even from fruit that hasn’t been harvested quickly enough. An infected tree will show wrinkling fruit with brown spots.
Treatment Options: To salvage an avocado tree that is infected with fruit rot, it’s recommended that tree owners remove the infected areas of the tree as soon as possible.
Tasty as avocados are, we humans are not the only ones who love an avocado tree. Avocado trees deal with many pests and insects, most prominently mites and thrips.
Mites are small pests that feed on plants and drain them of valuable nutrients and chlorophyll and can go as far as to kill your plants.
Thrips are slender insects with wings that feed on plants by puncturing and sucking up the contents.
