Talk:Oomycete

Someone added a taxobox treating these as members of an unranked stramenopile taxon, which was a direct subgroup of the eukaryotes. At the moment, though, we've been keeping the kingdom Protista and using ranks. The classification here is unsettled, and there are several different systems we could use here.

I think what might work best is to take the heterokonts as synonymous with the stramenopiles, as does Cavalier-Smith, rather than applying only to the algal forms, which may be paraphyletic. Cavalier-Smith uses a 5-kingdom system for eukaryotes, and we could move towards that, but for the moment I'm keeping them all crammed in a single division Heterokontophyta. However, it should be noted that's less standard for the expanded group than for the alga-only group. It may be that we want to revert the heterokont article to discussing only the algae, and have the water moulds as a separate division. In that case, should the expanded group be called the stramenopiles, which are stable but usually unranked, or chromists, which make a good kingdom but assume the haptophytes are related?

I would greatly appreciate any input other wikipedians had on this problem. It impacts a lot of protist groups, including some big names like kelp and diatoms. Josh 03:29, 11 Aug 2004 (UTC)

algae/fungi distinction and control methods

If water moulds are actually more like algae than fungi, does this mean that fungicides will be ineffective against them? Is this why Phytophthora cinnamomi has been so hard to control? njh 11:33, 20 September 2005 (UTC)

In short, yes. Fungicides in general work to break down chitin in the fungal cell walls. Since oomycetes lack chitin, those fungicides are useless. Don't let a chemical company tell you otherwise.

American Spelling

The American spelling of "mould" ("mold") should probably be included.

I agree with that.

Hell if I know why wikipedia doesn't default to US spelling.

Pythium causes less damage than Phytophthora??

Gee, I wish I knew this earlier!! Just joking! I realize in a forum such as this, it's important to take into consideration other people's views and be respectful. However, I find that Pythium spp. are just as damaging, if not more so, than their more specific cousins, the Phytophthora spp. Perhaps the view that Phytophthora spp. are more damaging comes from their visibility in causing the Irish potato famine, in addition to the versatility of their spores, which can be dispensed aerially or be aqueously motile. Perhaps a note could be included, with a pointer to my own revision under Pythium (which also includes the appropriate references.... natch)

what do water moulds eat?

Article Title

Is it really correct to redirect oomyctes to water moulds. Large numbers of the taxon are plant pathogens. (a Mentally Efficient Loonies And Nice Insane Elephants creation 13:39, 21 January 2007 (UTC))

I've moved the article from Water mould to Oomycete, per the request at WP:RM. There was already a non-trivial history at Oomycete containing the contribution details for some content that was imported into the current article in July, 2004. In order to preserve the history of that content, I swapped the two articles' histories, so what was previously at Oomycete can now be found in the history of the redirect currently at Water mould. -GTBacchus^(talk) 23:19, 19 February 2007 (UTC)

Thank you very much you've made me a happy plant pathologist lol (Million_Moments 14:17, 20 April 2007 (UTC)).

Found a half sentence with a line through it

I removed the sentence: water mold comes from everywhere and you can find it in jungles and other places. If you don't like something, you erase it, you don't just draw a line through it. Dream Focus (talk) 23:32, 16 December 2008 (UTC)

Peronosporomycetes

I read in microbiology by prescott, harley and klein 7th ed that the group name is now Peronosporomycetes (and read elsewhere that it has the synonym Peronosporea). Polypipe Wrangler (talk) 02:58, 15 November 2011 (UTC)
