I bought a bottle of confidor systemic insecticide today and am wondering if anyone can recommend the dosage rate?
The active ingredient is 15g/L imidaclorpid
The bottle recommends 10ml per 3 litres for most applications and bugs but there is also a 20ml per 3 litres rating which covers longtailed mealybug.
Was thinking of going right in the middle at 15ml per 3 litres but that is just a guess dosage rate.
My main concern is damaging or worse killing my cacti.
I have a very broad collection so unsure if the dosage would need adjustment for some species?
