How does one develop it?
Is there a genetic component? Onset of avocado hand develops suddenly when someone preparing to eat an avocado stabs themselves instead.
Why do people do that? They are also booby trapped. How so? You know when you cut an avocado down the middle, then twist the halves apart, to be left with two beautiful pear-shaped pieces, one with an empty well in the centre, the other with the stone or pit embedded in it?
'Avocado hand': Joy Behar and Andi Dorfman bring awareness to avocado affliction doctors warn about
I am familiar with that scenario. So people take the point of the knife and try to dig around it, then slip, and end up stabbing the hand they are holding the avocado with. Some sufferers from avocado hand experience nerve or tendon damage from which they never fully recover. Those fiendish Mexicans! So their entire delicious food culture was just a ruse to injure gringos? If only we could surround them with some kind of wall.
Good plan. In the mean time, the British Association of Plastic, Reconstructive and Aesthetic Surgeons wants safety-warning labels placed on avocados. You and many others. Eccles says he treats four people a week for avocado hand. Meryl Streep was afflicted inand many sufferers complain that the worst aspect is the stigma. So how do I avoid it? Is there a vaccine? Not yet, but you can try scooping the stone out with a spoon, or hacking down on the stone with the middle of the blade, then twisting to remove it neatly.

Cute avocado couple in love.The beloved pitted fruit, which is lauded by celebrities and regular folks alike thanks in part to its numerous nutritional benefits and pivotal role in guacamole, has been inflicting damage on stars left and right in recent years.
On the Tuesday, June 12 episode of The Viewcohost Joy Behar returned after a brief absence and recalled how her own perilous encounter with an avocado ended with a trip to the E. Successful surgery! Tendons and nerves have been reunited. Thanks for all the sweet messages. If only the avocado had been so kind. Two days later, the year-old took to the photo sharing site once more to post a picture of herself in a hospital bed with a bandaged hand.

The arrows denote the movement of pollen between the complementary flower types. The separation in time of the male and female phases has led most observers to believe that a vector or "pollinator" is needed to move pollen from one flower to another.
The European honey bee is the commonly used pollinator. The data from the pollinizer project suggests that the spatial placement of pollinizers may be critical due to the foraging behavior of the honey bee since most honey bees tend to forage in a relatively small radius of 1 to 4 trees.
We have been monitoring honey bee activity on avocado during the last year and have compared the efficiency of two honey bee races Italian and New World Carniolan. We monitored the percent of the honey bees visiting avocado flowers during the day. Figure 8. We used the presence of perseitol, a sugar unique to avocado, to assay for honey bee visitation.
The drop in the middle of the day approximates the time when the female and male flower phases are in transition Figure 9. Interesting data has been generated by this project. During the current year we are continuing collaboration with other researchers in Florida and Israel.
We hope to further elucidate the mechanism by which pollen is transferred from male to female flowers as well to understand the role of the honey bee. This information will assist growers in making informed decisions regarding the subject of pollination.

Insect Pollination of Cultivated Crop Plants. Table 1. Avocado varieties and flowering types. The critical first step, however, is the process of pollination which leads to fertilization and fruit set.
Pollination occurs when pollen is deposited on a receptive stigma. This poster describes some of the considerations pertaining to avocado pollination. The mature tree can produce in excess of a million flowers during the flowering period. The flowers occur in panicles of several dozens or hundreds of flowers. There are two different types of avocado inflorescences: determinate and indeterminate see Figure 1. In a determinate inflorescence the tip of the shoot that bears the flowers will end in a flower.
Indeterminate inflorescences, which tend to be more common in our environment, terminate with a vegetative bud. Figure 1. The avocado flower has both functional male and female organs. The male floral organ, which produces pollen, is comprised of the anthers and stamens.
The female floral organ is comprised of the stigma which receives the pollenstyle and the ovary.The avocado — more commonly known for gentrifying communities across countries — is poised to cause a spate of injuries this weekend.
If you think epidemic sounds far-fetched, consider this: the researchers estimated 50, avocado-related knife injuries occurred between andwith over half happening in the last decade. Avocado hand occurs when a person tries to remove the pit in a dangerous manner, such as with a knife, and ends up cutting themselves.
The consequences can be serious: avocado hand can result in damage to the muscles or tendons, and even the nerves in extreme cases.
And there we all were thinking the only problem with avocados is how they are causing a crisis in millennial home ownership.

Department of Agriculture plant hardiness zones 9 through Clusters of small green flowers appear in its leaf axels from January through March, and these should be followed by 3- to 6-inch bumpy avocados. But avocado trees may not produce fruit for a number of reasons, including being too young, not being pollinated fully and poor weather. Grafted trees can fruit in their first year, but avocados started from seed often won't fruit until they are 8 to 20 years old.
If your tree is a seedling, you may simply have to wait until it matures. Although avocado blossoms contain both stamens and stigmas, they aren't self-pollinating. When a tree's blossoms first open for a two- to three-hour period, they are female stage flowers, meaning the stigmas are ready but the pollen isn't.
The following day, they open for several hours as male stage blossoms, with plenty of pollen but stigmas no longer able to receive it. A-type avocados, such as "Haas" -- perennial in USDA zones 9 through 10 -- are female one morning and male the following afternoon.
B-types like "Fuerte," which grows in the same zones, are female one afternoon and male the following morning. Because the flowers open over a period of several days, it is possible for bees to carry pollen from A-type stamens to B-type stigmas one day and from B-type stamens to A-type stigmas the next. To ensure proper pollination of your avocado tree, make sure you have at least one tree of the opposite type as well.
Even if you do have the correct types of trees to provide proper pollination, freezing weather during their blossom time can kill the buds. Low temperatures during that period -- below 63 degrees Fahrenheit -- may shorten the already brief female stages in the flowers and cause pollinating bees to stay in their hives.
Heavy rains can also discourage bees not to mention that they often prefer to flit from blossom to blossom of the same tree instead of flying between two different trees. To prevent weather-related problems, only grow trees that are hardy in your zone, and pollinate the flowers yourself. You can use an artist's paintbrush to carry pollen from the stamens of whichever tree is in the male stage at the time to the stigmas on the female stage one. Hand pollination can make an avocado tree set 23 times as much fruit as it would have if the pollination were left to insects.
When an otherwise healthy avocado repeatedly refuses to bloom although it is at fruit-bearing age, consider scoring the trunk. This is a risky measure and should only be done after you have tried everything else, as it could endanger the life of the tree. To score a tree, use a sharp penknife to make a shallow horizontal cut through the bark, low on the trunk and extending only halfway around it.
Then draw another such cut on the opposite side of the tree but several inches farther up than the first one.
Don't attempt to connect the two cuts -- or to draw a line completely around the trunk -- because that will kill the tree. Carefully wipe the blade with a cloth soaked in rubbing alcohol before you use it to prevent the spread of disease.
