    Unhappy Is this Scale on my orchid?

    I bought this Pot. Little Fortune #15 from a vendor in MN and received it last week in bloom. I was planning to repot this weekend. I noticed, however, these raised areas on the leaf and pb of one growth and am afraid it is the dreaded scale.

    Yup...Looks like scale to me! Get out the Volck oil spray & the Malathion. 1/2 Tablespoon of each to half a gallon water. Mix well, and keep shaking...Spray all leaves & media, repeat in a week.

    Just wanted to share a link that might be helpful for identifying scale: Brown Soft Scale

    Be sure to click all the different links at the top of the page.

    Cheers,

    If you put your fingernail on one of those brown bumps and push slightly does it break? Scale you can scrape off with your fingernail and will squish easily with little pressure. I'm looking at the top photo and the brown bumps look too a-symetrical to be scale. I could be wrong but to me it doesn't look like scale. Although, I've only dealt with scale on citrus trees and not orchids.

    Bruce, Thank you. Digging through the links on that page took me a while. One of the best links, to my mind, was the National Pesticide Information link ( National Pesticide Information Center - Pest Control Information ) Within that page is a directory of least toxic pest control products which actually lists name brands. Very informative after looking at all those really ugly scale photos and drawings.

    Jason, No, it's not squishy. It's very hard. In that top photo you can see where part of the blemish broke off and there is green underneath. I swabbed fairly had with alcohol and had no results. Even the brown on the pb which looks soft is not.

    It doesn't sound like scale to me. Alother way to tell if your plant has scale is if there is a sticky residue. Scale will leave a trail of sticky stuff.
