Grease bands for winter moths in apple trees?

Asked January 20, 2018, 4:14 PM EST

Hi - What's your opinion / knowledge of grease bands in apple trees? I've read they can be helpful to prevent winter moths, once pupated, from climbing up the tree to lay eggs. Seems very sensible -- but the method doesn't seem widespread (among the holistic/low-spray types), so makes me a little skeptical. We've got ~80 trees, 40 years old. So far as I can tell, the word is out to generations of insect families that one & all are welcome here. ;) And a fair amount of leaf damage that I'm trying to rule out possible causes. I know I've missed half the winter moth crawling season...but figured I'd send an email to see what you thought. Thanks!

The grease bands that you mention would be minimally effective. The major pests of apple trees are codling moth and plum curculio. Take a look at our website for more information and control of these pests. See Non chemical control and a spray schedule from Va Tech. Be sure to practice good sanitation (pick up infested fruits) to prevent overwintering insects.
