I have a magnifier on order so I should be able to get a much closer look early next week.

I believe they did come in with the planting stock as there are 2 rows of the same variety in one of the tunnels that are barely effected and those are plants i grew myself.

I have decided that that all the plants need to be removed as they are just too far gone, I will replant in different tunnels next year and run a program of predatory mite releases.

From what I have read spinosad can be effective but coverage is a problem?

I could pull more saps but I don’t really see the point at this stage.
