Thanks Alison. But the link led to an error. It said the requested article was not available on that site.

I have used systemic insecticides, mainly dimethoate and imidacloprid in my nursery for over 20 years and do not have a significant mite problem.

Hi All,

I'm not so sure about how "safe"... see the study below.

We have known that using systemic insecticides
won't help with spider mites.
But did you know it can increase them?

Be careful with BATS (Bayer advanced tree and shrub for any not knowing already.)

Treating with this product can also have a stunting effect on some plants, but

I haven't found a study for it. -- Yet.

You can=E2=80=99t go safer than imidacloprid, marketed under names such as Pronto. Google it. Your garden centre should have. It is systemic, absorbed through leaf surfaces. They have yet to determine the lethal dose for a rat, I understand, and plants tolerate it very well. It controls sucking insects for a month, so that when eggs hatch, the larvae will feed and die also.
