OLIVE TREE BLIGHT. A couple of years ago I contacted a Texas researcher who had identified a phage specific for the olive blight, but was brushed aside. Since then nothing has happened. It could solve the olive blight problem. Equally, quorum sensing bacterial pheromones would be a promising approach. Are the agriculture science advisors asleep?
