Re: Mealy bug friendly?

Xannydoo: An extra thought. If you are having annual outbreaks, yet treating with Confidor, I wonder if the problem is actually repeated introductions, rather than a failure of the insecticide? In other words, are you adding new infected plants to your greenhouse each year? And here's a link that's ...

Re: Mealy bug friendly?

Hi Xannydoo! Confidor is excellent (IRAC Insecticide Group Code 4A). If I have to apply anything serious, this would be my first choice. It is certainly used by cacti/succulent nursery professionals in hot countries such as South Africa but I have no experience of Australian commercial nurseries. As...

Re: Mealy bug friendly?

As part of the quarantine process I remove all compost and dip the entire plant in provado. This seems to stop mealy bug completely, although it doesn't eliminate the need for quarantine for other pests Great. That really is the way to make sure. I don't go to quite those lengths - specifically ref...

Re: Mealy bug friendly?

Some brilliant answers above. On the subject of quarantining a collection, the telling point here is self-discipline. For those who are familiar with the marshmallow test, perhaps the cacti/succulent version should be called the "mealy bug test". The one and only mealy bug attack we've had - so far ...

Exactly, Carl. So every local library should have a BCSS branch leaflet on the noticeboard. Well designed, colourful, with immediate impact.

Re: Books for Beginners (Local Library)

I hope that Ralph's words that libraries "have had their day" are proved wrong - but I fear they are realistic, though not yet, based on my latest PLR returns (Public Lending Rights). As a child, I benefited from using public libraries. As an author, I have made sure that - in addition to sales - li...

Re: Crushed brick substrate

Peat in a garden centre seems to be an endangered species, Rod! :sad: I'm not sure about any remaining retail products - other than the fact that the "bags" get smaller and smaller, costing more and more. But there should be something like "wetting agent added" on the packaging. Years ago, I had 700...

Thankfully, Rod, most professional supplies of peat have a wetting agent incorporated to counteract this issue.

Re: Crushed brick substrate

Phil's suggestion above of using multi-purpose compost is good. Following on, I wasn't joking in my first reply about using peat. It's vastly superior to multi-purpose compost (which covers such a wide range of stuff adding up to anything from "reasonably good" to "dreadful" - the best of which usua...

Re: Crushed brick substrate

Conrad: A quick search has failed to highlight our local brickworks, yet it is still very much in business. A few phone calls to bricklayers or house builders in your area might provide some leads. If you have access to a lorry or transit van, travelling beyond your area might still prove to be cost...
