Is Marathon 1% Granular good for my greenhouse to control whiteflies?
I have a small 12x10 greenhouse, last year I had a lot of white flies. How can I ensure that they do not hatch in the new season? Do you recommend another insecticide?
Yes, the OHP Marathon 1% Granular is a great product for you. The rate will depend on the type of plants you have. Please look over the label on page 3 to see the rate that is needed.
