I have seen quite a few threads about insects making a mess of some outdoor grows so I thought I would take a closer look. I had been checking them and had not noticed anything until today. These are on a NL photo.
Some type of borer. I also opened up a bud on a Jack Herer auto and did find a little green caterpillar / worm. It had the same brown stuff on it and is what drew my attention to it.
Uncertain if it is one or different critters causing the damage. I was going to spray with spinosad but not sure if that would take care of the borers. Same with insecticidal soaps. Recommendations.
Also, should I cut out all stems with bore holes?
