Is the cause of pine wilt disease a chemtrail? 松枯れ病の原因はケムトレイルか?2018.3.9

Heisei 30(9th) March, 2018 Saitama prefecture Niiza city, Japan.
It was a heavy rain from yesterday to early today. By way of example, chemtrail spraying frequently occurred for the past 3 days. As for the clouds after today, very artificial and unnatural clouds cover the sky.
The cause of pine wilt disease is not caused by pine insects as generally told, pine is weakened because soil itself is contaminated and acidified, so that pine nymphs parasitize there, It was stated in a certain article. I thought that there was a possibility of contamination of soil by chemtrail.
