    Default Your treatment for hard scale?

    I got in a new plant shortly before my trip and I now have several infested with hard scale. Thought I would check and see what everyone else uses to control it. I have used both malathion and Orthene in the past.

    Any other suggestions?

    I spray with vegetable oil 2 tbls to a gallon of water. This will smother the scale, just make sure that your plants aren't in direct sun until they dry, as the sun will fry them. It worked for me. I had a bad infestation in the spring, sprayed a couple of times and voila, they're gone.

    I go heavy with the malathion and take a toothbrush and remove as much of it as I am able to remove. Once you get an infestation, it is hard to get rid of it completely if you have lots of plants, really close together. The stuff likes to hide until it has grown big enough to do some damage. argh! I hope you kill those pests.

    I have used horticultural oil with success. My last outbreak, this summer, I cleaned the plants with a toothbrush and alcohol and them used Bayer Tree & Shrub insect control as a spray and a drench. It contains Imidacloprid 1.47%. This is the systemic that is found in Merit but at a reasonable cost and purchased at a boxstore.
