greenhouse cucumbers

For the last couple of years I have tried growing cues in my G/hse, they start off really well, then they get what I think is mosaic virus and all the leaves dry up and go brown and the palnt dies.

I isolate them from the tomatoes and things seem to be slightly better, they are watered daily with when possible rain water.

Should I spray the cues like I do the Toms or is there something else that needs to be done :( ?

 

A lot of greenhouse cucumbers leaves dry up and go brown towards the end of summer due to red spider mites, could it be these?

 

Could be I know they are small any ideas how to A) identify / spot them?
B) Stop / deal with them?

 

Nic, I think virus tends to distort the leaves.
I think Steve could be right.
Red spider are my biggest problem on most plants, even in the garden.
The only thing that works for me these days is the preditors that you can buy.
First you really need a hand lense of about 10 times magnification to I.D. them, or in really bad cases you can see the webbing on the leaves later in the season, but by then its too late.

 

Predators - some thing like "nematoads" sorry cant spell!
