    Any suggestions for dealing with scale at this time of the season? I am seeing scale, but not really active crawlers. I am not sure if a product like talstar, or even hort oil will be of benifit at this time. Any sage advice?

    I used Talstar F mixed with hort oil at a summer rate to control scale, with good success at this time last year.

    You can use hort. oil, just be careful with high temps! You can also use Malathion.

    I believe Merit used as a soil drench is also effective.

    Merit in a drench will solve it fer sure.

    Cheaper would be talstar and the lowest rate of oil. I use a quart or so in 100 gals of H2O with my talstar and bayleton.

    Hort. oil and Merit. Spray all leaves and branches and drench the roots. Follow-up in 14 days.

    What is the function of the hort oil? Is it some sort of sticking agent or something?

    The oil will suffocate them

    Too hot for oil right now. 102 today. I sprayed them with Talstar a few days ago. I'm beginning to think the scale are dead but they're just stuck to the leaves. I guess they don't just automatically fall off the plant when they die.

    How do you tell if the scale are alive or dead?

    pinch the scale with your fingernail if it oozes its alive. on the sagos I have treated I use a water hose to blast off the dead scale.
