Plant Your Tree in a Smart Location. If you’re about to plant a citrus tree in your backyard, it actually matters where. If at all possible, plant your tree on the southeast corner of your home. Here’s why: the killer freezes of recent decades came into Florida with a strong northwesterly wind. If your tree is planted near your house’s southeast corner, your home acts as a shield to block a direct hit from damaging winds. It’s important to know that citrus trees exposed to temperatures 28 degrees or below for 4 or more hours will result in fruit damage, while trees exposed to temperatures of 24 degrees or below for 4 or more hours are vulnerable to wood damage which harms the tree itself.

Protect Your Tree during a Hard Freeze. What if your tree is already planted elsewhere in your yard and vulnerable to the elements? If it’s three to five years old, you may be able to use this DIY hack involving a trash bag, a light bulb and an extension cord. Depending on the size of your tree, you can visit www.uline.com or your local hardware store to purchase extra large trash bags up to 96 gallons.  When the threat of a hard freeze approaches, slide the trash bag over the tree, seal it around the base and put a 100-watt lightbulb inside. Keep the lightbulb turned on overnight. The heat generated by the lightbulb generates enough heat to protect the tree from plummeting temperatures, while the trash bag traps the heat inside.

Nourish Your Tree the Organic Way. For the best in tree nutrition during the winter, Benny recommends a one-two punch of compost and organic brown sugar. According to Benny, January is the best month to apply a 50-lb bag of Black Kow compost available at Lowe’s or Home Depot.  Apply an entire 50-lb bag of compost under each citrus tree in your yard. Spread it out from the trunk to the edge of the tree, forming a circle of compost under the tree.  Next, take two cups of certified organic brown sugar (yes, has to be organic and brown!) and sprinkle it on top of the Black Kow compost and then water the mixture. The organic brown sugar acts as a food source for the beneficial microbes (aka bacteria) in your soil to break down the compost and release the nutrients in the compost, which in turn feeds the tree. This program is an effective way to help the tree fight citrus greening disease (link this) and pests while producing delicious, nutrient-dense fruit.

Don’t Over-Irrigate. Believe it or not, you don’t want to overwater your backyard citrus tree through winter. The tree needs to “stay asleep,” or stay in dormancy. According to Benny, watering more than once a week for an hour would cause the tree to “wake up” and flush, leaving it susceptible to new growth damage should an unexpected freeze occur.

Choose the Right Citrus Varieties. If you want your citrus tree to thrive, choose a variety that grows well in backyard soil. Depending on when you want to harvest your fruit, Benny’s recommendations include:

  • Sugarbells, available around Thanksgiving
  • Navel oranges, available around Christmas
  • Red Grapefruit, available around mid-January
  • Valencias (a great juicing orange), available around Easter

UF researchers say citrus greening can be managed with new biological and chemical controls http://www.unclematts.com/uf-researchers-say-citrus-greening-can-be-managed-with-new-biological-and-chemical-controls-2/ http://www.unclematts.com/uf-researchers-say-citrus-greening-can-be-managed-with-new-biological-and-chemical-controls-2/#respond Tue, 14 Aug 2007 18:07:25 +0000 http://unclematts.wordpress.com/2007/08/14/uf-researchers-say-citrus-greening-can-be-managed-with-new-biological-and-chemical-controls-2/ more]]> GAINESVILLE, Fla. — Canker topped the list of worries for the Florida citrus industry until citrus greening – described as the world’s most serious citrus disease – was found in groves last year.

“In the long term, the industry can live with and manage the canker problem, but citrus greening is a fatal disease that’s an even larger threat to the state’s signature crop,” said Harold Browning, director of the University of Florida’s Citrus Research and Education Center in Lake Alfred. “In other areas of the world where greening is a problem, it has never been successfully eradicated.”

The disease, which slowly weakens and kills all types of citrus trees, causes fruit to become lopsided and taste bitter, making it unusable. Fruit does not develop the desired color, hence the greening name. There is no known cure for the disease, which is on the U.S. Department of Agriculture’s select list of threats to plants and wildlife regulated by the Agricultural Bioterrorism Protection Act. Greening does not harm people.

Browning said the fatal bacterial disease is transmitted by the Asian citrus psyllid (Diaphorina citri), a tiny insect that is now widely distributed throughout Florida, and the disease has been found in more than 440 locations in 11 counties. Browning said it’s not practical to eradicate citrus greening, but the spread of the disease can be slowed with an effective integrated pest management program (IPM) that includes limited use of systemic insecticides and beneficial insects that attack the psyllid.

The introduction of a beneficial wasp was the first step in an expanded research program by UF’s Institute of Food and Agricultural Sciences to develop a wide range of best management practices to prevent greening from destroying the state’s $9.1 billion citrus industry, Browning said. UF researchers are also developing management programs to combat canker.

Marjorie Hoy, a UF professor of entomology and biological control expert, said the psyllid was first detected in two South Florida counties in June 1998. At the time, the psyllid was considered to be a significant pest, and although it did not appear to carry the deadly bacterial disease that causes citrus greening, it made establishment of greening more likely if the disease were introduced. Damage caused by the psyllid included stunting of new growth and sooty mold formation on the honeydew produced by the psyllids.

“When citrus greening started showing up in citrus trees across the state in September 2005, we knew that that we had a potential disaster on our hands, and that the psyllid was carrying and transmitting the deadly disease,” she said.

In an attempt to reduce populations of the Asian citrus psyllid, Hoy and Ru Nguyen, an entomologist with the Florida Department of Agriculture and Consumer Services, imported two natural enemies of the psyllid from Taiwan and Thailand. After evaluating the parasitic wasps under quarantine conditions to make sure they would be effective against the psyllid and not harm the environment, they began releasing the biological controls about six years ago.

“One of the beneficial wasps (Tamarixia radiata) is now widely established throughout Florida, feeding on the psyllids and reducing their population by as much as 80 percent in some locations between August and November,” Hoy said. “We’re also relying on naturally occurring predacious insects such lady beetles, lacewings and spiders that consume more than 90 percent of psyllid eggs and nymphs.”

Unfortunately, even one psyllid can transmit the deadly greening disease, so biological control cannot be the only tool in managing greening. Any control will require a holistic approach, Hoy said.

“Management tools that are developed should be compatible with these and other natural enemies that suppress citrus pests such as mites, whiteflies, scale insects, leafminers and mealybugs,” Hoy said. “Indiscriminate killing of their natural enemies could produce serious pest outbreaks.”

What complicates control of citrus greening is the fact that symptoms begin to show up in trees several years after the trees are infected by the psyllid insects, said Ron Brlansky, a professor of plant pathology at UF’s Lake Alfred center.

“Lack of early detection of the systemic bacterial disease is a major problem for the citrus industry,” he said. “Once the symptoms show up, it’s too late to save the tree.”

Brlansky said early symptoms such as leaf mottling and yellow discoloration may be mistaken for other problems such as nutritional deficiencies, and laboratory tests are needed to determine if greening is the problem. The disease can also be identified by cutting open small and poorly colored fruit and looking for aborted seeds.

He said the UF research program will attack the citrus greening problem in three ways by developing best management practices for the bacterial disease, improving diagnostic methods and testing the effectiveness of systemic insecticides to stop transmission of the disease by the psyllids.
