I have just discovered aphids on my blackberry and raspberry plants after finding ants crawling over them, I have put Antrid down but the ants are not going for it as the aphids are more attractive to them.
Do I use horticultural oil or neem oil to deal with the aphids and how do I apply it, once a week until the aphids are gone or every couple of days, I am guessing that after rain I need to reapply it once the rain has stopped?
How long after use do I need to withhold picking fruit (there is no ripe fruit yet, it is only just starting to grow)?
Thanks in advance for your help.
