SirLSD Posted October 15, 2019 Share Posted October 15, 2019 no pics YET. this scale type problem results in white/grey scale that is easily rubbed off with your finger. it has a little brown dot in the centre of the white scale. they flourish in shaded areas and result in large patches of brown scar tissue on the cacti. found in perth. what is the solution to this problem? 1 Quote Link to comment Share on other sites More sharing options...
XavierDass Posted October 15, 2019 Share Posted October 15, 2019 I've had success with neem oil, used once the sun is soft and setting, to avoid adverse affects from the increased photo-toxicity. It works by suffocating scale and other pests such as aphids. I find it best used in a regimen as a prophylactic rather than a treatment (once original infestation is stamped out). I have seen some people report adverse affects on their cacti from various horticultural oils, though applying around sunset has been working well for me.

Evil Genius Posted October 15, 2019 Share Posted October 15, 2019 Get a brush and scrub them off carefully, then start treating it with a pesticide like Azamax, Spinosad, Imidacloprid, Pyrethrum,White Oil, Alcohol etc. All of these can cause adverse reactions or burns, so make sure to follow all instructions. 1 Quote Link to comment Share on other sites More sharing options...
