Chemical spray damage

This is what happens when you spray a plant for mealy bug and put the plant back on the bench in full sun.



The plant is M.uncinata P 477 and has a rule I would of put it under the bench for a few days. It does not happen much but I do fine that it is these green bodied plants from Series Mammillaria that suffer this kind of damage most of all.

Oh thats sad, but a good warning about the potential that the instecticides and miticides we use can have their downsides as well.
I try to spray in the evening, so that by morning the plants have dried enough.
We don't have a thread on what insecticides and miticides people use for mealy bugs, red spider mite and other pests such as thrips. I'll start one.
