Title: Citrus Greening concern?
Post by: Isaac-1 on December 13, 2018, 05:33:02 PM
Does this look like signs of citrus greening on Satsumas?    The majority of the  fruit on this tree this year has these small green specks, even after several cooler nights with temperatures around or just below freezing the last 2-3 weeks.      There are also the occasional smaller all green somewhat deformed fruit though this accounts for only a small fraction of the  fruit on the tree, maybe 1%

With greening disease the fruit will develop lopsided smaller on one side of the fruit like one half of the piece of fruit didnít mature well. The leaf with greening will have irregular yellow patterns with one side of leaf having different pattern of yellowing than the other side of the midline vein of leaf. Green spots on satsuma fruit doesnít mean HLB; deformed fruit might. Look online for photos of greening leaves and fruit.

As you know, satsumas are ripe and ready to harvest when still a little green. I think your fruit looks normal. I have been harvesting mine with some green areas still in peel/skin and itís good. HLB infected fruit mature from the calyx button down instead of from bottom up; if HLB, the top half of fruit will be yellow/orange with the bottom part of fruit is green.

Thanks for sharing your thoughts on this, I have looked at the information out there online and in many case evidence of greening does not seem to be clearly defined in the online guides, and there is great variation in the example photos that show greening on fruit.

In my reading on HLB I had missed the tendency of them to turn orange on the top half first, some of my fruit on this one tree are bit green blotchy but tend to favor green on the top half.  My concern was primarily based on this only occurring on the one tree, and not any of my other Satsumas, though each one is a different variety, this one has thicker more pebbly skin and often more pear shaped fruit, it is also usually the least flavorful of my trees, though the one with the largest fruit.

What variety is it? Usually my Kimbrough is like that, bigger than owari and not as sweet , but this year my owari is bigger and sweeter and ripened quicker than kimbrough. My kimbrough also gets more shade than my owari. Different factors, different weather in different years, different varieties, etc.

I believe this one is Brown Select, I also have 2 mature Owari's as well as young Armstrong Early, Louisiana Early, St Ann's, and a Miho.  The one in the photos matures about a week before my Owari, and has much looser skin.
