I have some aphids on my indoor plants, was looking for a way to kill them rather than water-washing the plants. Bought a bottle of Brunnings Rose Spray the other day from Woolies to try it out. Yesterday I noticed the Bug Kill Spray next to the Rose Spray and thought I probably should get that one instead. Upon inspection, they have exactly the same active ingredients: 0.1g/L Tau-Fluvalnate, 0.05g/L Myclobutanil. Apparently Brunnings have a whole range of sprays, I didn't look into all of them. This is so confusing. Thought this might help someone else out there to not buy both.
Also for black spots on roses or any type of fungus, baking soda works wonders, the trick is to find a spray bottle that do not become clogged up by it. Or use less baking soda but spray often.
It also might blow your mind that many bug sprays for plants have the same active ingredient, Pyrethrin/Pyrethrum.
