Blk Sigtka - I officially hate FL - Page 2

MsKitty, I never thought of it that way. Rose black spot is also fungal, so it's worth a try!

Caloosamusa · 05-15-2009, 10:58 AM

Most garden centers have copper sulfate in liquid solution, the easiest application form. Just dilute it per directions on the label. It is toxic to the plant if too strong(concentrated). Good growing!!

I just wanted to update some Sigatoka info regarding FL. I think Rmplmnz said he was not aware of Sigatoka in FL, and perhaps, other members are not either.

Quote:

In October 1998, symptoms of black Sigatoka (2) were observed on several different cultivars in a collection at the University of Florida's Tropical Research and Education Center (TREC) in Homestead (25°30(prime) N, 80°30(prime) W). During preliminary surveys, the disease was found at four of eight locations in a 15 km(^2) area to the north of TREC. Disease severity, rated as the youngest leaf spotted (YLS), averaged 4.8 on the most susceptible cultivar, Rajapuri, at one of the locations. The extent and history of damage at this site indicated that black Sigatoka had been there for at least 3 to 4 years. The prevailing east to west winds in the Caribbean, and highly variable incidence and severity of the disease also suggested that the pathogen had been introduced to the area on infected seed pieces (suckers) rather than by wind or rainblown ascospores from Cuba or other affected areas (1). The presence of the disease was confirmed after the following characteristics of the pathogen's anamorph, Paracercospora fijiensis, were observied on affected leaves: simple conidiophores occurring singly or in groups of two to six with one to several septa, scars, and usually a broadened base; and conidia much more abundant on lower leaf surfaces, straight to variously bent with one to several septa and a conspicuous scar at the base. Single-ascospore cultures were recovered from Rajapuri and are stored at CIRAD/FLHOR in Montpellier. This is the first time black Sigatoka has been reported in the continental United States. Banana is a minor but significant tropical fruit crop in southern Florida, with fruit valued at over $2.5 million per annum. Production from Hua moa, Silk, and other important cultivars will probably be affected as the disease becomes established in this part of the state. First Report of Black Sigatoka in Florida.

While not a about Black Sig, here is a story from out local paper about a citrus disease going around:
Doomed lemon trees leave man a bit bitter - The Post and Courier

Doomed lemon trees leave man a bit bitter

If life gives you lemons, don't tell the state.

They will not offer you any lemon aid.

Pat Mellen learned that the hard way, when Clemson extension agents showed up at his downtown house recently with a leaf plucked off one of his lemon trees.

While passing by, they noticed the tree — which sits behind the wall around his house — appeared to be infected with citrus greening, a disease that U.S. officials fear could devastate the nation's citrus crops all the way to California. Already, the disease has taken a toll on crops in Asia, Africa and South America.

Mellen said his mistake was letting them in, where they found traces of the disease on both his trees. Now, they are slated to be cut down and Mellen has no recourse, no way to appeal the decision.

He's had one of the trees for 16 years, and every year it gives him two bushels of the sweetest lemons you ever tasted.

"If I was a serial killer moving state to state on my way to California, I'd have more rights than I do right now," Mellen said Friday, just before agents showed up to spray his trees — a precursor to cutting them down. "I offered to let them use one of the trees for testing, asked them to let me have one more season, but they said no."

Chris Ray, head of Clemson's Department of Plant Industry, said there is little he can do. The state is under quarantine, and the law says they must destroy any infected tree, lest it help the disease — carried by bugs the size of gnats — to spread.

In a recent canvass of downtown Charleston, they only found the disease in two places: Mellen's house and another private residence a few blocks away.

"We don't relish the idea of going and cutting anyone's trees, but that's the only thing we can do," Ray said. "We couldn't bring them back to health. They're going do die. It's a matter of when, not if."

Mellen is upset because lemon trees take a long time to grow, and he fears he'll never have another one. Of the two trees, one produces a number of lemons, and they still taste great. Eating fruit off trees with the disease won't hurt you, but the disease discolors the fruit.

Mainly, Mellen feels helpless, and is understandably not a fan of laws you can't argue against. But that's the government.

He got a brief reprieve Friday, when agents decided it was too windy to spray. But they will be back. Nothing can save his trees. Mellen is trying not to be as bitter as store-bought lemons.

"I have nothing against Clemson," Mellen said, "but I wish they could play football."

Rmplmnz · 05-17-2009, 10:13 AM

Citrus greening is a very serious issue and has the potential to wipe citrus out of Florida and other states. Florida is already seeing a huge decline in citrus production. The groves near where I work have been turned in to planned developments or abandoned (the fruit is left to rot).

USA Today article form 2007 on greening:

Disease threatens Fla. citrus industry - USATODAY.com

From the web:

In which direction is Florida headed?

In 1998, Florida had 785,900 acres of trees that produced 13,583 tons of citrus.

Last year, Florida had 554,400 acres of trees that produced 7,236 tons of citrus.

Ok, I have to ask...the bananas in your avatar..what are they?

Very nice BTW!

proletariatcsp · 05-18-2009, 12:33 AM

Are we just going to run out of good fruit to eat, or what? I am really glad I didn't buy a fifty-dollar orange tree that I wanted.

I was thinking about where the Sigatoka could have come from. I know the article says they originally suspected it was air borne from the carribean but they thought it was more likely to have come from infected planting material. For the infection in Homestead 1990's that might be true.

For me, I have not received any new planting material. I bought my banana with about 8 or 10 leaves and it did not have any leaf spots. I find wild bananas all the time and I have never seen Sigatoka on them. I was stumped as to where I could have gotten Sigatoka from. Then, one day I was sitting outside eating a store bought banana and it dawned on me!

I must have tossed the peel by the bushes and touched my ice creams without washing my hands. Son-of-a-seeded-nanner. You would think that bananas would come with a warning label about Sigatoka and hand washing right under the words "Chiquita" if, the industry gave a **** about the continual spread of the disease right?

What do you guys think?

mskitty38583 · 05-18-2009, 12:36 AM

they dont want to give any warnings like that. most people would get parnoid and quit buying the produce.

Yeah thats probably true. BTW, I bought a systemic fungicide specifically for Black Spot on Roses, it may have been beneficial to the bananas but it does not do anything to treat Black Sigatoka. Black Spot is a mold-like fungus like Sigatoka but they are two very different problems. The systemic fungal does not contain copper and was therefore, inaffective. According to members and internet research, commercial plantations use copper as the main treatment and prevention of Sigatoka, so I would imagine copper and infected leaf removal (detrashing) are probably the only treatments, period.

Good luck with your nannas this season MSKITTY,

supermario · 05-19-2009, 10:31 AM

I had a few citrus trees succumb to citrus greening. I destroyed them immediately to try and avoid my last 3 remaining citrus trees from enduring the same fate. It is indeed a serious problem as SEVERAL local nurseries do not carry them anymore. I personally give up as well. If they get the disease, they will be replaced with another tropical.

As for the Sig.. don't worry. They sell 'Liquid Copper Fungicide' in pint-sized containers at any Home Depot. You can find gallon jugs online as well. I use an ortho sprayer with a dial for measuring.

just j · 05-19-2009, 08:06 PM

can some one tell me if this could be black sig. its on my new thia black only on the bottom leaves i got it from wellsprings on ebay wondering if anybody else bought one of these from them and had the same markings

lorax · 05-19-2009, 08:07 PM

No. If it were Sig it would be manifesting in the new growth.

just j · 05-19-2009, 08:08 PM

if it is how is it transmitted from plant to plant

just j · 05-19-2009, 08:11 PM

im in wisconsin so i didnt think it was sig. but can i bring it into my house true plants i ship in from other places and do the leaves have to touch or is this plague air born or what

supermario · 05-19-2009, 08:15 PM

Hey Lorax, good to see you here on the good ol' world wide web. We've discussed gardening before on 'the helpful gardener forum'. Haven't been on there as often though. Hope all is well!

lorax · 05-19-2009, 11:10 PM

J, Sigatoka is a fungus and there are two means of transmission - by air and by contact; the first route allows fairly wide dispersal and the second is dependant upon contact with infected material. There are also a very specific set of conditions that favour the growth of the fungus. However, it's highly unlikely that it's made it all the way to Wisconsin.

sunfish · 06-01-2009, 02:16 PM

What ever caused the black marking on my plant wasn't Black Sigtka. I didn't spray and all new leaves are clear of any black .
