This article needs expansion and sources. An image of the disease affecting a plant would be nice, too. Rose32 22:56, 6 May 2006 (UTC)[reply]

Jargon getting a little thick

To me this phrase:

This color is made of asci that break through the cuticle of the leaf. One asci consists of eight ascospores that create conidia, which are ejected in early summer and moved by methods of rain and wind.

is pretty difficult to comprehend, even with a passing familiarity with botany. Is there some way it could be phrased more accessibly, or a brief translation for the laity? Jake (talk) 04:41, 8 November 2010 (UTC)[reply]

I tried a little wikifying to make it easier (for me) to follow. I still wonder about something like

This color is made of asci (spore bearing cells) that break through the cuticle of the leaf. ...

I feel a little out of touch with the current wiki style for such things. Jake (talk) 04:49, 8 November 2010 (UTC)[reply]

Another thought, I copies some of the crunchy bits relating to the fungus to Taphrina deformans where a reader might be expect to encounter more technical terms relating to fungus physiology. Perhaps this page could then take a "gentler hand". Jake (talk) 04:57, 8 November 2010 (UTC)[reply]

Organic gardener's note

I haven't ruled out the use of antifungals, some of which are organic; however, as I learn more about interactions of microbes in soils and on plants, I'm more reluctant to use anything that destroys all fungi, except in situations where the life of the tree is threatened. I have controlled both brown rot and leaf curl for two (warm, wet) springs using actively aerated compost tea. The theory, similar to that supporting probiotics in humans, is that a large, balanced population of microbes tends to keep all of them in check. Read "Teaming with Microbes" by Lowenfels and Lewis - well researched, well written.

Article Needs a Major Rewrite...

In general it's poorly written. For instance what does this mean: "Different areas in climates depict the type of fungicide used and how often, since experiments have shown that the fungi are temperature-dependent."? Some parts of the article sound as if they were not written by a native English speaker, which is not a crime of course, but should be cleaned up by someone who can write well and is interested in the subject. I cleaned up one small section. Chafe66 (talk) 22:08, 22 April 2012 (UTC)[reply]

Removed "Future of" Section

The "Future of" section was complete garbage. The only useful part was the link, so I replaced the paragraph with a single sentence describing the link and renamed it "USDA 1992 5-year plan." — Preceding unsigned comment added by 199.16.140.30 (talk) 17:37, 23 October 2012 (UTC)[reply]

I don't see the relevance of this section. The section does not discuss leaf curl and nothing in the article talks about whiteflies. — Preceding unsigned comment added by 98.238.157.77 (talk) 17:36, 19 April 2018 (UTC)[reply]

The Whitefly sentence you rightly criticise has already been copied to Begomovirus#Transmission where it belongs. Whitefly transmits viral infection, not fungal infection. I am now removing the "leftover" whitefly sentence from this leaf curl article. 128.232.193.185 (talk) 16:07, 13 March 2019 (UTC)[reply]

Removed Trichoderma treatment claim

I have removed this paragraph, because no citation has been provided despite a request more than 2 years ago. The only relevant literature I found on the internet for the search terms "Trichoderma, leaf, curl" was a commercial pdf on Trichoderma harzianum by Professor Harman, and it does not mention peach leaf curl at all.

"The most successful means of treating leaf curl organically is spraying with a Trichoderma mix, which is a natural organic fungus which feeds on the other fungus. Whereas copper applications often defoliate the tree, Trichoderma will only attack the area where the leaf curl is on the leaf, the remaining section remains intact and continues to grow. Regular applications of Trichoderma can eliminate leaf curl completely. Trichoderma should be applied at leaf burst and then 2 or 3 times through the season. However, as a living organic substance Trichoderma cannot be applied in conjunction with chemical applications. citation needed|date=September 2013" — Preceding unsigned comment added by 81.135.37.250 (talk) 14:57, 23 December 2015 (UTC)[reply]

Infected leaves - leaving, removing or clipping?

The article currently states that removal of leaves is possibly not effective in stopping the disease spread. Removing infected leaves is a trade-off between weakening the tree further, and stopping the infection from spreading. In my own experience, a good compromise is to snip off the infected part of a leaf in the early stage of infection - this stops the fungus from spreading to the rest of the leaf. And from dripping down spores to leaves below during rainfall. Does anyone know of a citable source for this conservative method? — Preceding unsigned comment added by 81.131.171.213 (talk) 08:54, 24 December 2015 (UTC)[reply]

Peach Leaf Curl

Good morning David, I see you have reverted my transfer of information from the Leaf curl article to the Begomovirus article. Two favours I ask of you: please look closely at my changes specifically with regards to whitefly control, and you will see that my changes make biological sense. Please re-instate my version, thanks. Secondly, can you then please re-name the Leaf curl article as "Peach Leaf Curl"? Much appreciated. 86.170.122.151 (talk) 10:05, 25 March 2017 (UTC)[reply]
