How to avoid pollination?

[Pisti]

Hi there! I plan making a hop yard in Hungary, and my question is: is it a problem if my hops get pollinated by wild hops (it's naturally growing here..)? if yes how can I avoid it? How far can the pollen travel? Thank you

for me this is not a problem. the English leave the male plants and the cones are often full of seeds.

tip 1) find and cull wild males
tip 2) favor triploid varieties which will yield less seed content
tip 3) find buyers who don't fuss too much about seed content
