I think we’re going to see a rapid expansion of the Citrus greening disease in Southern California in this coming year,” Grafton-Cardwell Research Entomologist at UCR Riverside said in a speech this week. .

Citrus General Discussion / Re: Sunburn????????
« on: Today at 03:45:36 PM »
Looks like sun burn.  The problem was that the tree's needed to be brought into the direct sun light slowly,by first putting them in shade, and gradually moving into direct sunlight a little at a time.  Like DWF Citrus wrote, cover the trees with some type of shade cloth.  I don't know if the burnt leave will re-green, but with care the new growth should be OK.

They grow them in a mold.  Square watermelons have been around for some time.

I picked my last two Dekopon fruit today.  Since the variety is alternate bearing, next years crop should be a small crop. Guess I need a second Dekopon tree in order to get a good crop every year.

Plus not all mutations are superior varieties, some mutations are inferior varieties. Even then it could take 5- 10 years before fruit developed to determine if the new mutant is worth while. However it is always an adventure. Good luck.

The odds of a mutant must be every slim, taking many many many  seed germinations.

Heinrich, thanks for the pictures.  I really enjoyed seeing natures struggle to survive.   

A Florida nursery, Southern Gardens Citrus Nursery, is proposing the release of a GM virus, Citrus tristeza virus, which has been engineered to express bacteria-fighting proteins found in spinach. The GM virus, which has been undergoing controlled field tests since 2010, would be grafted -- not sprayed -- onto citrus trees in Florida. USDA has announced its intent to launch an environmental impact statement on Southern Garden's proposal

baccarat0809 yes but there is no GMO citrus sold, either on the commercial or private market.  As far as I am personally concerned I don't care if a product is GMO or not.

Some companies market their food product as “non-GMO” to create a nonexistent distinction that gives them a competitive advantage (sometimes at a premium price). For example, Tropicana Orange Juice includes the “Non-GMO Project” seal on its package, yet its sole ingredient is oranges, and there are no commercially grown, genetically engineered oranges. Every brand of orange juice is naturally “non-GMO,” provided the only ingredient is oranges.

Ponderosa lemons taste much like a  Eureka /Lisbon lemons.  The fruit of the New Zealand lemonade tree can be eaten in hand directly off the tree,  They taste pretty much like lemonade.

Silvain it is sure easy to see the Poncirus parentage in your tree.

In 10 years, Florida's round orange production fell from an average 342 boxes per acre down to 163 boxes per acre. That is a 52% reduction.
The report also noted break-even or negative cash flow groves are selling at discounted prices. The University of Florida benchmarks the typical all-in production costs for processed oranges is $2,235 per acre. Given that, the break-even number for a grove would be 225 boxes per acre receiving $2.28 per pound solids delivered (assuming 5.86 pound solids per box).

No not organic, they are conventional sprays.  All of the treatments will work quite well.  If you are seeing the deficiency at the same time as your tree is flushing new growth, the tree  will most likely correct the deficiency on its own, after the new growth matures. The amount of manganese in the soil is in trace amounts.  When the tree is putting on new expanding foliage, the tree's root system has a hard time supplying enough manganese to the tree.  After the growth flush is done, the tree's root system normally catches up. I know of no organic product that contains manganese.  In either case whether an organic product or not, manganese is manganese is manganese.

Really not sure of the maturity time for Flying Dragon.  Flying Dragon is of course a slow growing tree.   I have four two year old FD trees growing at this time that are 2-ft. tall that have not yet flowered.  My guess is at least 5+ years to begin fruiting.

The one most often used for a manganese deficiency is a foliage spray of manganese nitrate, you can also use manganese sulfate, or Southern Ag's Nutritional spray.

Mainly Citrus spp., at least two species of Murraya, and at least three other genera, all in the family Rutaceae.

Citrus General Discussion / Re: Groves in Central Florida
« on: April 18, 2017, 10:43:26 PM »
At the present time in Florida it is very expensive to maintain a HLB infected grove to remain as productive as possible (and almost 100 percent of Florida groves are infected).  Some growers cannot afford the cost, and some barely can.  Those that spray, provide extra nutrition, and avail themselves with the various scientific programs, have groves that look as good as possible.  Others have abandoned their properties which then become Asia citrus psyllid generators..

If they were actually determined to have HLB I think the trees would have quickly been removed.

Lory, the  link below shows many good pictures of Citrus Greening symptoms.  There is even one picture of what  "corky veins" look like..

Not sure if your leaf symptoms are showing symptoms of greening.  Yellow veins is common in nitrogen deficiencies, but the balance of the leaves shown on your link are still very dark green, so at this point that rules out nitrogen deficiency.  Citrus greening symptoms normally show a more blotchy appearance.  Another greening symptom is what is normally called "corky veins".  I'm not sure what "corky veins" looks like, perhaps you can find that out on the Internet.

bigalxx15,  your tree's leaves might have an iron deficiency, but I'm not 100 percent sure.  However, the tree's leaves are showing a magnesium deficiency.

gozp, the deficiency your leaves are showing is manganese, not iron.  At this time of year these "transient" Manganese deficiency symptoms are VERY common.   These transient symptoms are due to a marginal supply of available manganese in the soil, which the tree roots temporarily are unable to extract enough Manganese to supply the large rapidly growing new flush of leaf growth.  Normally the leaves will return to the normal dark green color as the grow flush ends, and the roots are able to once again catch up.  However, you can apply a manganese spray such as Southern Ag Nutritional spray if you wish, or in most cases simply do nothing.   In the rare event that the leaves still look deficient upon the completion of the flush, there is always time to apply manganese. 

Inspectors from the California Department of Food and Agriculture are going home-to-home inspecting trees after the devastating citrus disease Citrus Greening was detected in La Habra.
