The dairy farm next door has maze about 600 metres from my Strawberry popcorn, what distance is safe to say i wont get any cross pollination.

There is a thread here somewhere where Joseph has done the math on this... have to find it...

Thanks for that link, i see Joesph saying there- (I have never observed cross pollination between my popcorn and sweet corn fields which are located 3000 feet apart) , so thats a 1,000M - one km. Ok so i'm looking at half that distance here, but still he says - (an average speed of 10 mph the pollen falls below silk level after 25 feet.)
Given this i think i can worry less

At that distance (unless the land features really channel the wind) it sounds like you should be in pretty good shape. You might make a conscious effort not to save seed from the edges of your plot - they can help trap any stray pollen that drifts in.
Another way to incorporate "distance" is by using time. If you know when the other farmer plants, and the variety DTM (maybe you noted pollen shedding in the field?) then that is another way to help reduce cross-pollination.

Its flat land between the two blocks and no other trees besides my tall boundary shelter radiata pines. The maze block is to my west but thankfully its produced its pollen after the long period of strong to gale westerly quarter winds have eased
