Title: Spraying against plum fruit moth
Post by: dandelion on July 12, 2007, 21:33:30
I got one of those pheromone sticky trap thingies to monitor my Victoria plum tree and caught quite a few moths, so I've sprayed the tree with liquid derris. Question is: Do I need to repeat this later in the season? And if yes, how often?
