    Default Orthene

    Anyone use this for pest control. I bought some to rid the orchids or bugs before i bring them inside for winter. Those of you that use it, do you spray or make a batch and dip you plants? I've never done this before so all advice is appreciated.

    I spray it on the plants. I use Orthene granules mixed at a rate of 1 teaspoon per gallon of water. Orthene is a systemic organophosphate so use gloves and a mask when spraying it. You don't want to get much on your skin. Take a shower right after applying it to your plants. Orthene is also known for it's strong odor. The odor only lasts on the plants for a couple days but it really stinks. Store it where children can't get to it and where the odor won't bother you.

    Orthene is a staple in my arsenal of "big guns", as it is both a contact killer and systemic.

    It is important to eradicate and "hitchhikers" in the media, so when I treat with it, I use an Ortho Dial-n-Spray hose end applicator and soak everything thoroughly. Repeat at one-week intervals for three applications to make sure all critters are effected, both to ensure complete coverage, and as such treatments only affect adults, so you need to wait for the eggs to hatch, and larvae and pupae to mature.

    If you REALLY want to be effective, add Enstar AQ to the treatment. It is an insect growth regulator (IGR) that prevents those early stages from maturing. No maturation = no reproduction.

    Looks like I'm adding another product to the arsenal to fight the pests (Enstar AQ). Thanks folks.

    cheers,

    I did use Enstar one year and it was very effective. It's expensive though.

    Well I went ahead and used it. I brought some plants home from the new comers orchid society meeting that had scale on them that I did not notice. I will treat at least three more times.
