If you want to have a list of Fungicides, then please do so at some article like List of fungicides, not the main article. Thanks, snoyes 07:19, 2 Sep 2004 (UTC)

Why ? I should have thought this was a good thing to have - see article on Insecticides Tomcrisp7 10:36, 26 November 2006 (UTC)

There are problems with this article :

Fungicides are not commonly used on corn (maize) since there are few serious diseases of this crop, and economic results are difficult to obtain from the use of fungicides.

Also, some fungicides are genetically modified ? What utter rubbish. Crop plants can be genetically modified to obtain different results from pesticides, but fungicides ? These are chemicals and therefore contain no genes to be modified ! Astonishing.

Also, systemic fungicides are systemic in the host plant, not the fungus.

In addition, the article is being used as a pesticides scaremongering platform and this is not acceptable.

I agree. Most fungicides are no more harmful to humans than salt, and thats a fact I have from a table given in my lectures, which must have come froma reputable source. On the 8th March I have 3 lectures of fungicides (which will have references), but this needs to be changed urgently so I will do what I can now.

But what exactly does your lecturer mean? Does s/he mean that to an average person, high salt intake is of greater concern than fungicide residue in food? This is very different to claiming that all fungicides are no more toxic than salt! I'm removing the claim, unless we can get a reputable source that states it completely unambiguously. –Adrian J.

No what I meant is that it takes less salt to kill you than it does some fungicides. Million_Moments 16:12, 23 August 2007 (UTC)

Questions Article Should Answer[edit]

  • Are there general classes of chemicals that are fungicides?
  • How in general do the clases of fungicidal chemicals work?
  • What are a few common names for fungicidal chemicals?

I am not an expert. These are questions that should be answered for the general reader.--F3meyer 20:01, 19 July 2007 (UTC)


What about systemic and protectant fugicides? —Preceding unsigned comment added by (talk) 12:23, 30 December 2007 (UTC)


Added a section on the history of fungicide development and use. Could probably use some more information on modern day usage (which I hope to add when I can collect some more research on it) but for now it provides the reasons behind the development of the first major fungicides and the development of synthetic ones CPRI04 (talk) 06:03, 22 December 2008 (UTC)


This needs some serious work as it contains errors. Phenylamide (such as metalaxyl and benalaxyl)resistance in potato blight has developed in the UK (I've corrected this), the use of mixtures delayed it at best. Even this may not be correct as it was also linked to the introduction of more virulent strains from Mexico and the spread of phenylamide resistance may be linked more to the spread of these strains than the use of phenylamides. Whether the use of mixtures is a useful strategy for preventing resistance is debatable. There is some evidence from UK Defra/LINK funded work on QoI resistance that suggests it may help. Mathematically it shouldn't work unless there is some interaction between the different components (see the arguments of Mike Shaw, a researcher at Reading). What it will do is ensure that if one component fails you still control the disease.

Another error is that polygenic resistance will revert. Reversion will only happen if there is a fitness penalty, this is probably more likely with monogenic resistance. If I can find references I'll get to work ..... Maccheek (talk) 09:50, 18 March 2009 (UTC)

Natural fungicides[edit]

I've tagged this as disputed because it lacks high quality sources. Looking at the sources cited they indicate that these substances do have anti-fungal activity in-vitro but that is very different to them being used (or being safe to use) as fungicides. The section is also WP:UNDUE to be honest, since these are not what the vast majority of fungicides are. SmartSE (talk) 10:09, 8 August 2014 (UTC)
