No it won't have a negative impact. It looks like Agribon 19 or similar. I've got nectarines and plums covered with it right now for bird protection. It also makes great shade cloth for adjusting new plants to full sun. Many other uses.

You could put the 19 right over the whole patch if needed for bird protection. The plants and fruit would do fine from a light standpoint with everything covered.

Great, thanks!
