Citrus General Discussion / Citrus Fruit Drop
« on: March 28, 2021, 05:31:52 PM »
According to research by Professor Vashisth of the University of Florida, insufficient water status limits fruit growth during the initial early stage of the young fruits development, immediately after flowering. This will cause fruit drop when the fruit matures. To minimize fruit drop, growers should focus on their irrigation and nutrient management practices. In particular, to prevent water stress beginning in APRIL (important). Water stress reduces the number of fruits and the eventual size of the fruit — and increases the likelihood of premature fruit drop.

Citrus General Discussion / Sugar Belle Orang & HLB
« on: March 02, 2021, 06:19:45 PM »
Studies of the resilient qualities of the Sugar Belle will lead to the development of a cultivar that completely resist  citrus greening. Sugar Belle's tolerance also positively impacts phloem regeneration.  Phloem is the tissue that serves as the plant's plumbing system  to move sugars produced in the leaves throughout all plant parts, from roots to fruit. HLB blocks the plumbing, but  Sugar Belle has a unique capacity to grow new "pipes" bypassing the plugged pluming.

Citrus General Discussion / Hanging Fruit And New Blooms
« on: February 03, 2021, 03:13:05 PM »
It has long been known that when last years fruit are left hanging on the tree, new blooms will not develop on those branches.  I have a New Zealand Lemonade tree that I have been eating off for most part of a year.  Today I noticed that every branch the still retains fruit did not flower, therefore those branches will not produce fruit this year.

Citrus General Discussion / My In Ground Cara Cara
« on: December 06, 2020, 04:33:28 PM »
The fruit on one branch of my in ground Cara Cara is producing fruit with orange flesh.  The cultivar Cara Cara originally begun as a limb sport of a Washington Navel orange tree in Venezuela , and has occasionally shown in some trees limb reversion back to the mother variety of Washington Navel orange.  Time will tell if this branch continues to produce blond fruit.  My tree is presently about 11-feet high and 12 feet wide and 15 to 20 years of age..

Citrus General Discussion / Things To Remember When Pruning
« on: November 25, 2020, 03:11:47 PM »
Vertical branches or vertical flushes are very vigorous with a lot of vegetative growth. Horizontal branches (up to 45°) produce most of the fruit and most of the quality. Weaker branches toward the bottom of the tree tend to produce less fruit and are more susceptible to disease.

Many members on this form remember Bomand.  He was a frequent poster until he came down with Corvid.  It has been 5 or 6 weeks since he became sick, and we have not heard anything as to how he is doing.  I'm concerned, as the weeks go by.  Keep him in your prayers and your thoughts.  God help Bomand.

Citrus General Discussion / HLB Could Be Gone In 3 Years
« on: October 05, 2020, 04:29:11 PM »
According to a news article released by the University of California Riverside (UCR), scientists there have found a substance which may be capable of controlling citrus greening disease. The disease, also known as huanglongbing (HLB), has devastated citrus in Florida and in other regions worldwide. It also threatens California crops.

The article says the new treatment effectively kills the bacterium causing the disease with a naturally occurring molecule found in wild citrus relatives. This molecule, an antimicrobial peptide, offers numerous advantages over the antibiotics currently used to treat the disease.

Citrus greening disease
UCR geneticist Hailing Jin, who discovered the potential cure after a five-year search, explained that unlike antibiotic sprays, the peptide is stable even when used outdoors in high heat, easy to manufacture and safe for humans.

“This peptide is found in the fruit of greening-tolerant Australian finger limes, which have been consumed for hundreds of years,” Jin said. “It is much safer to use this natural plant product on agricultural crops than other synthetic chemicals.”

Currently, some growers in Florida are spraying antibiotics and pesticides in an attempt to save trees from the CLas bacterium that causes citrus greening.

“Most antibiotics are temperature sensitive, so their effects are largely reduced when applied in the hot weather,” Jin said. “By contrast, this peptide is stable even when used in 130-degree heat.”

Jin found the peptide by examining plants such as the Australian finger lime, known to possess natural tolerance for the bacteria that causes citrus greening disease. She isolated the genes that contribute to this innate immunity. One of these genes produces the peptide, which she then tested over the course of two years. Improvement was soon visible.

“You can see the bacteria drastically reduced, and the leaves appear healthy again only a few months after treatment,” Jin said.

Because the peptide only needs to be reapplied a few times per year, it is highly cost effective for growers. This peptide can also be developed into a vaccine-like solution to protect young healthy plants from infection, as it is able to induce the plant’s innate immunity to the bacteria.

The peptide can be applied by injection or foliar spray, and it moves systemically through plants and remains stable, which makes the effect of the treatment stronger.

The treatment will be further enhanced with proprietary injection technology made by Invaio Sciences. UC Riverside has entered into an exclusive, worldwide license agreement with Invaio, ensuring this new treatment goes exactly where it’s needed in plants.

“Invaio is enthusiastic to partner with UC Riverside and advance this innovative technology for combating the disease,” said Invaio Chief Science Officer Gerardo Ramos. “The prospect of addressing this previously incurable and devastating crop disease, helping agricultural communities and improving the environmental impact of production is exciting and rewarding. This is crop protection in harmony with nature.”

The need for an HLB cure is a global problem, but hits especially close to home as California produces 80 percent of all the fresh citrus in the United States, said Brian Suh, director of technology commercialization in UCR’s Office of Technology Partnerships, which helps bring university technology to market for the benefit of society through licenses, partnerships and startup companies.

“This license to Invaio opens up the opportunity for a product to get to market faster,” Suh said. “Cutting-edge research from UCR, like the peptide identified by Dr. Jin, has a tremendous amount of commercial potential and can transform the trajectory of real-world problems with these innovative solution

Citrus General Discussion / A Lesson Re-learned
« on: September 27, 2020, 05:34:28 PM »
I have a Tango mandarin growing in a 5-2-1 medium.  Some time back the tree set its first fruit, and I have been watching it develop.   Last week I noticed that  the medium was quite dry, so I watered it well.  5-2-1 is a rapid draining medium.  Two days after the watering, I notice the fruit has split its peel open.  Most probably from drinking in water faster then the peel could expand.

Citrus General Discussion / Turunji - A Citrus You Eat Like An Apple
« on: July 11, 2020, 02:27:18 PM »
Citrus medica ‘Turunji’ never ceases to amaze the gardener with its over sized fruit. Related to the Etrog, the inner white rind is deliciously sweet and can be eaten like an apple. Remember to train the plant when it’s young to develop thick branches to support the weight of the fruit. We recently picked a 7-pound fruit measuring 14" long on a two-year-old SEEDLING. I grew a Turunji years ago. Might be a fun cultivar to cross pollinate with a Finger Lime. It is a fast bloomer from seed.  I think I will order another one, just for the fun of it.  Much of this post was taken from Logee's catalog.

Citrus General Discussion / Marathon Mandarin
« on: June 28, 2020, 03:52:29 PM »
Marathon mandarin: This variety (formerly known as 1420) is a new seedless, easy-peeler that will be available to Florida’s fresh citrus growers next year. Marathon fruit are easy to peel and are completely seedless under any pollination conditions. Fruit develop good external orange color as the season progresses, are well-flavored and pleasant, and very convenient to eat because of good segment structure. Fruit are larger and firmer than Bingo, and Marathon can be harvested in most cases without the need for expensive clipping.

The name Marathon was chosen to highlight the variety’s unique attribute: an exceptional ability to hold long in good condition on the tree. In the 2015 season, fruit were mature internally by mid-August, although externally they were still green with just the beginning signs of color break. As the season progressed, the Brix went from 12.5 in mid-August up to 17.4 by mid-December. Very significantly, the acidity declined only slightly, and the fruit retained its firm texture while external color became deeper orange. The ability to store fruit for a longer time on the tree can give growers and packers greater flexibility in harvesting to optimize returns and expand the marketing window.

Marathon has been released under the UF/IFAS FAST TRACK citrus release program. An invitation to negotiate will be launched later this year by Florida Foundation Seed Producers (FFSP). Certified trees will be provided to licensed Florida citrus nurseries in early 2019 for budwood increase, and it is expected that Florida growers will be able to place tree orders in mid-late 2019.

Citrus General Discussion / New Second Flush Occurring Now
« on: June 08, 2020, 10:12:50 PM »
An Alert:.....Several days ago I noticed the beginning of a new second flush on my citrus trees.  The first day I noticed it, I happened to have a hose in my hand.  Therefore, I sprayed all the new flushes with a semi firm water spray to knock off any insects.  Tonight I went around and sprayed them with a HO solution.  This kills all the insects (mostly thrips) that love to feed on the tender growth.  At this warm time of the year if these insects are left feeding on the new growth, the leaves will become deformed in wrinkly forms, and will remain in that condition for the rest of their lives.  To insure healthy looking new growth, this should be done every 2 or 3 days until the new growth obtains some firmness to the growth.
