Mr. Dean Knuth has kindly passed along an article to be shared with Sweetwater Valley Civic Association and members of the community.¬† Mr. Knuth stated “Since there are so many Canary Island Date Palms in Bonita, I thought that you would like to know about the invasion of the South American (black) Palm Weevil that is hitting us hard. There was an article on it a few weeks ago in the south bay section of the Union Tribune, but they had no solution to the problem.”
