mobile Posted March 3, 2009 Report Share Posted March 3, 2009 (edited) There have been several posts on the forum over the years with regards to neem oil as an insecticide. Whilst surfing around the internet I came across THIS site on neem oil which I found interesting. Edited March 3, 2009 by mobile Quote Link to comment Share on other sites More sharing options...
Cas Posted March 3, 2009 Report Share Posted March 3, 2009 Thanks.. it was an interesting read. I was wondering, while reading it, why neem oil affects some of my tropical sundew so, particularly derbyensis and ordensis, but not my paradoxa. My ordensis was affected by aphids and I applied a diluted 50/50 neem-water mix via a small paint brush at the spots where I saw the little bugs. 10 mins later I rinsed the plant thoroughly. A day later, those spots where the diluted neem was applied started turning black. I'm wondering now whether I should amputate those parts of the leaves.

You need to buy neem oil that's used for gardening then you know how much water to mixed with it . Quote Link to comment Share on other sites More sharing options...
mobile Posted March 4, 2009 Author Report Share Posted March 4, 2009 There are recipes for making your own neem oil spray on the website I linked to. Direct links: http://www.discoverneem.com/neem-insect-spray.html http://www.discoverneem.com/neem-oil-spray.html For a neem garden spray 0.5% to 1% is a good general purpose solution. Depending on the purpose you may want to increase that to up to 2%. Quote Link to comment Share on other sites More sharing options...
Cas Posted March 4, 2009 Report Share Posted March 4, 2009 Thanks.. I didn't know you could buy neem oil as an conc product (prob not in Singapore anyway). My neem oil is actually from a neem garden spray. I diluted it a further 50% and it still blackened the leaves of my ordensis (wasted parts now trimmed off).. It's fine on my burmanni and capensis (esp. resilient against neem oil spray).. just the 2 plants I mentioned are esp. sensitive to the stuff. I'm wondering why this is so if its effect on insects is hormonal rather than a neurotoxin. Quote Link to comment Share on other sites More sharing options...
Cas Posted November 22, 2009 Report Share Posted November 22, 2009 I was looking this up yest and realised I'd been using an insecticide containing pyrethrins and not neem(!).. So pls ignore my earlier ramblings Quote Link to comment Share on other sites More sharing options...
