Prevention of gladiolus thrips.

donna_in_saskApril 10, 2012

I only grew glads once, I was so disappointed when they succumbed to gladiolus thrips. Were they already in the purchased corms, or did they appear when the plant was put in the ground? I read that you can soak them in Lysol or bleach in order to kill them prior to planting. Has anyone tried this and was it effective?

I think you would be better off using a systemic insecticide like imidaclorpid. Should be available at any garden center -- look for a "rose and flower" type product, may be a combination fertilizer/insecticide compound.

Thanks for answering my question. I actually just heard about this insecticide that you mentioned...I'm a bit wary about using imidacloprid since recent findings have linked it to colony collapse disorder in bees.
