Can I use Bonide Liquid Copper Fungicide Concentrate on lawn for treating rust?

There is rust on my lawn, lawnmower and my shoes.

Answer:

Bonide Liquid Copper Fungicide Concentrate is labeled for applications on lawns and treating rust. Mix 1.5 to 6 fluid ounces with 2.5 gallons of water and apply to 1,000 sq. ft. For best control, begin treatment 2 weeks before disease normally appears.To reduce rust, mow frequently to reduce rust spore production. Water and fertilize lawn as required to avoid moisture and nutrient stress. Water before noon to allow grass to dry. Apply this product when disease first appears, and repeat at 7 to 10 day intervals for as long as needed. In frequently diseased areas, prune adjacent trees and shrubs to reduce turf shading and to improve air movement.
