Looking for such a "miracle cure" we came after intensive research on the Internet on the drug Neem and thus Bayer Bio-Insecticide Neem.
So ordered and mixed immediately after receipt. The dosage is explained quite simply and understandably. Our roses were very generous sprayed with the Bayer Bio-Insecticide Neem and then it was wait and see.
Since this is so is a biological agent, we knew from beforehand that the action requires some time and this should also schedule.
The first 2-3 days did not say anything to that aphids felt a fiddle on our roses, this with their lodgers unfortunately rather less.
But from the 4th day you could watch the aphids have been less and after more than a week was not a single aphid longer be found on our roses daily. And this has continued until today so. We really had to spray only once and for the rest of the summer, our plants were absolutely pest-free.
