phloom Posted March 28, 2007 Ive used a fungicide called Banrot a few times (probably unnecessarily) and im wondering whether my cactus will retain any of chemical for long periods? I can't find a proper report about it, which probably means there's nothing to worry about.....but in relation to cactus.....does anyone know if they retain chemicals/toxins for an extended period? cheers, Phloom Share this post Link to post Share on other sites
paradox Posted March 28, 2007 well i don't personally know about it but i was reading a thread the other day which was talking about this and supposedly many cacti do retain toxins for long periods. (warning: second hand knowledge) Share this post Link to post Share on other sites
ENtiTY Posted March 28, 2007 (edited) Yeah its been discussed here before, not that long ago actually... about a month or so. The discussion was about Lophs and if they absorb the chems from sprays etc. If I remember correctly they hold onto them for quite a while. EDIT: Here is the thread might or might not be useful.

marsha Posted March 28, 2007 well do they absorb more than an orange or a tomatoe or an apple like seriously how much is left in the plant and have any real tests been done? a lot of us common folk eat veges from woolies so are these any worse?? Share this post Link to post Share on other sites

occidentalis Posted March 28, 2007 Is Banrot a systemic or surface fungicide? What is the recommended withholding period for other edible plants (fruit etc)? Share this post Link to post Share on other sites
phloom Posted March 30, 2007 Yeah, I did see that thread about the 'toxic' loph....Im dont really think that a plant will retain any chemical in dangerous amounts for extended periods ie. 6 month +. Banrot (a systemic fungicide) doesnt have a published withholding period as far as im aware (not on the packet or MSDS), i think because its intended use is for soil drenches on seedlings. For leafy plants i think it would be free from contaminants within 2-3 months as a guess, obviously depending on climate and water etc. but for cactus in not sure, any out there is good on their cactus biochem/botany?

AndyAmine. Posted March 30, 2007 Ive given up on keeping my plants safe for ingestion, its a total shitfight at my place for various reasons and it make my hobby jst one big pain in the ass... which is something its not meant to be. Im gunna get systemics into all of them and then go for an organic garden via cuttings and grafting from the inorganic /toxic collection when I move somewhere more suitable. Personaly, I would only ever consider the progeny of such cacti safe for consumption..... Share this post Link to post Share on other sites
blangschpeer Posted April 10, 2007 Wouldn't the size you sprayed it at also be of consideration? Obviously a couple of seedlings that were sprayed (when consumed mature) would be a hell of a lot safer than a mature specimen that has been sprayed, with lots more surface area and had the chance to absorb everything over a week or two.
