Used it for a year

This does a fair job in performing as advertized however it does not totally keep roses from getting black spot. And of coarse insects have to have a few bites before the insecticide works. Over all it did not do as well as spraying every 7 to 10 days but was a lot easier. My biggest CON is that It is pretty pricy and doesn't do very well at totally stopping black spot from coming back.
