Slicko starts with ... The pictures below show diseased parts of the most recent flush on my lanes late orange tree. The diseased part covers about half of the circumference of the branch. Upward of the diseased part there is increasing choloritic effect on the leaves. In places there are shiny parts where it appears as though sap has emerged and hardened. It effects a significant part of this last season's flush. Tree was planted in mid year 2014 and is on dwarfing rootstock. The disease is not evident in my remaining five citrus trees. Obviously I would like to know what the problem is and how I can deal with it Mick

Slicko says... Thanks everybody for your continued interest in my orange tree. I am reluctant to take more vegetation off the tree as there is another lesion halfway up the main stem and to do so would leave me with not much tree left. I have treated it with a copper fungicide and intend to spray it with horticultural oil in the next day or so. I understand that Mancozeb plus is a combined miticide and fungicide so I'll give it a breather before I hit it with that. The other citrus trees all appear healthy. The Washington navel is showing signs of emerging new growth and flowers however none of the other trees are that far advanced so it may be a few weeks before the lanes late displays new growth. I did some research on the hydraulic situation and now understand to a basic level of what it's about. I don't recall any root damage when I put it in the ground. All very interesting stuff!

jakfruit etiquette says... I dont think its root damage, but root damage can be caused by borers + weevils eating the roots, fungal infection girdling the roots etc, not just direct damage at planting or digging near the tree. Usually fungal infections of leaves and stems show some signs of sporulation/ fungal hyphea/mould activity etc. Good Luck. | About the Author jakfruit etiquette vic 3rd August 2015 11:26pm #UserID: 5133 Posts: 915 View All jakfruit etiquette's Edible Fruit Trees |
