Can I use Ferti-lome Tree and Shrub Systemic Insect Drench on boston ferns?

Every year, caterpillars infest my outdoor boston ferns and devour the tender tips of new growth. I assume they have hatched from eggs laid by moths, which then lay more eggs. Can I use the Ferti-lome systemic drench to stop them? What dilution? Is one treatment enough? Thanks!


You would need to use a foliar spray to control caterpillars like the Fertilome Borer, Bagworm, Tent Caterpillar & Leaf Miner Spray. The dilution would be 2 ounces per gallon of water and reapplication times with vary with the type of plant/tree you are treating on.  Complete instructions can be found on page 12 of the product label.
