Hi All
As a follow up to your posts here, I’ve usually found that the normal-size insect netting (not ultra-fine) usually lets through both whitefly and mealy cabbage aphid which can then reach plague proportions in the protected conditions inside the netting. However,I do live in Cambridgeshire where brassicas (oilseed rape) can be somewhat of a monoculture so we may have more of these pests around than most. Also, if anyone’s interested, you CAN get insect netting in black which is less obtrusive. I’ve seen it on the ‘Harrod Horticultural’ website, but not tried it myself.
Finally, there are some compensations for the rape fields. View from allotment.
