Hi all,It should definitely improve things.
When I started looking after our glasshouse it had the most amazing infestation of White-fly, Scale Insect, Mealy Bug and Red Spider Mites, and after while I didn't have an in date spraying certificate and after about a year of not spraying I was forced to get some biological control organisms. I'd never improved things with the White-fly or Spider-mites while I was spraying, and in late summer the White-fly were an active hazard to breathing.
I'd worked in commercial horticulture, where the answer to all pest problems was a liberal dose of <
"Temik">, and I was still in the "
better/more toxic/more frequent application will make things better", so I didn't hold out much hope.
Pretty soon it became apparent that some biological control worked brilliantly (
Encarsia for White-fly), some was OK and some instantly escaped through the ventilators (
Cryptolaemus).
Phytoseiulus, the predator of spider mites was OK, they cleaned the plant you put them on but they didn't really spread to new plants.
They would <"
be good in this situation">.
