Leafhoppers and tomato viruses
hi, I've been invaded by an army of leafhopper nymphs. they ae about a cm long and bright green. (I think they are potato leaf hoppers) I know that leaf hoppers vector two maijor tomato viruses aster yellows and curly top virus.
So far the leaf hoppers have been mainly tageting my sweet 100 tomato (only tomato planted out) and my magnus coneflower.
Besides the damage that the leafhoppers do themselves (mutated leaves holes and sap sucking)my main concearn is my plnts being infected by a virus .
since infection only takes one bug I need to keep the bugs off my plants for the duration of the attack
I would like to know What I should do about the leafhoppers to save my coneflower from asteryellows and my tomato from aster yellows and curly top virus.
I would also like to if at all possible deal with the leafhoppers organicly.
I don't think spraying or hand picking is going to be realistic at all since although It may provide enough control to keep damage to a minimum it won't stop all the bugs. maybe something like mousquito netting would be effective if my plants are not already effected?
The other thing I'd like to know is if there is anything I can do to prevent this virus if a vectoring leafhooper has already landed on one of my plants. Neither plant shows any symptoms of either virus yet but doesn't it take awhile for symptoms to develop ater the plant is infected?
Thank's so much for all of your help!
