Hi There,
I was hoping that you could assist with products to use to kill the fungus causing the mould and also the mealy bug which appears to have infested the plant. I have approximately 20 metres of bamboo about 4 metres high and its looking a little sad, but that could be winter as well.

Answer: Hi Michale,

Thank you for contacting us regarding sooty mould on bamboo, sooty mould is caused by sap-sucking insects in your case mealy bugs. The insects secrete a sugary substance that goes black with mould over time, hence its name. You may notice there are ants around, as they are also after the sugary substance. Once you control the mealy bugs the black sooty mould will disappear over time or you can wash off with soapy water. The product you need to apply is Confidor. Try the sachets and mix with water would work out cheaper comparing to ready to use bottle, you can read more information in the following link: http://www.yates.com.au/products/pest-control/insects-concentrates/bayer-confidor-garden-insecticide-sachets/#VAp3ZJoyKxgDDQzi.97

Hope this helps and happy gardening.
