Conserve

  • Foliar Spray

Conserve® SC is a spray applied insecticide designed to control a number of pests. Spinosad, the active ingredient in Conserve®, is derived from the fermentation of a naturally occurring organism, uniquely combining the efficacy of synthetic insecticides with the benefits of biological insect pest control products. Along with its ease of application, Conserve® offers quick insect control upon contact, and unlike other products, it does not cause phytotoxicity in plants.

Conserve® SC is labeled for the following tree and shrub pests:

Lepidoterous larvae such as:  bagworm, cone moth, fall webworm, gypsy moth, hemlock looper, budworm, tip moth, caterpillars, budworms, tent caterpillar, tussock moths.  Sawfly larvae such as european pine, pear, and redheaded pine.  Also labeled for leaf-feeding beetles, thrips, gall midges, spider mites, pine tip moth, dipterous leafminers.

One quart yields 145-533 gallons of spray. See the Conserve® SC Product Guide for more information.

    • Judith,

      The efficacy of any of our products has more to do with the pest you are trying to treat, rather than the type of plant to treat. Conserve works well against many caterpillars and some insects. Lets find out what you are treating for, then we can choose a product!

      • That’s totally right! Ants are rarely the primary problem, it is all of the other critters or decay that attracts them. Get rid of the underlying problem and the ants will find another food source.

    My dinner plate hibiscus are under attack from the Hibiscus sawfly larvae. I’ve picked them off; sprayed them with insecticidal soap (Concern) two days in a row on top and bottom of the leaves and they still keep appearing. Will the Concern soap kill them or do I need something more powerful to blast the little buggers?

    • Linda,

      It really depends on the size of the larvae, usually at this time of year control is pretty difficult because they are so large. You might consider a stronger, even systemic insecticide or plan to treat in the early spring next year. Inspect your hibiscus early in the season, and once you see those little buggers begin spraying. They will hatch over about a month, so you will have to keep watching for them if you use a soap or oil. Some of the more chemically insecticides have a longer residual and might offer you more protection.

  2. Wow that was unusual. I just wrote an very long
    comment but after I clicked submit my comment didn’t show up.
    Grrrr… well I’m not writing all that over again.
    Anyways, just wanted to say fantastic blog!

    • The Tree Geek says:

      Jim, Conserve should be applied in late spring for best effectiveness. Treatments in fall will not help because the insect is protected in the bag this time of year.

    I grow water lilies. Something is making numerous holes in the leaves (about 2mm), but when I turn the leaves over, I don’t see anything moving. Sometimes the leaves will have a clear gel on the underside but I have never seen anything hatching from them. Sometimes there is a trail of pin-point marks on the top-side of the leaves. Can you guess what the cause is. Will Conserve do the job and is it safe for fish?

    • The Tree Geek says:

      Unfortunately we do not sell any product that will not be harmful to aquatic life (invertebrates). M-Pede insecticidal soap is an organic option for insect control but is listed as hazardous to aquatic invertebrates. I would recommend trying a water garden resource shop for a product safe to use in a pond with fish. Sorry we could not be more help!

  4. Ben says:

    Will conserve treat the various forms of scale?…We have scale on some of our shrubs (its currently late spring here)

    I have just sprayed them anyway so I will guess I will find out.

    • The Tree Geek says:

      Hi Ben!
      Thank you for the inquiry.
      Unfortunately Conserve is not labeled for scale insects, armored or soft.
      You might see some control but I cannot recommend it to you because it is not labeled for such use.
      Other scale control products we sell that work well are M-Pede insecticidal soap, RTSA Horticultural Oil, and Transtect. These are all effective against armored and soft scales.
      Please let us know if you have further questions!
      Thanks,
      Alyssa

    My fir tree is covered with bagworms. The top of the tree is all brown. Can I spray now for bagworms or is it too late?
    Will the top of the tree come back. Thank you!!!

    • John Hillis says:

      For bagworms, treat with conserve around midsummer when larvae are actively feeding at app. 600 growing degree days. Re-apply every 7-14 days through 900 growing degree days.

  6. Alan says:

    Spinosad has become the treatment of preference for codling moth on apple trees. Why is this product not listed for codling moth.

    • The Tree Geek says:

      Hi Alan,

      There are many pests that the product treats, and the list would be quite long if we listed all of them. Generally, we list a few common insects that most people would be treating for as a reference, and we are always here to assist if there are any questions. Codling moth is listed on the label for Conserve, and would be a good treatment option.

  7. Patrick says:

    Is this product safe around honey bees? We were ravaged by gypsy moth last year and are planning a neighborhood spraying. I have honey bees and need to know what precautions to take.

    • The Tree Geek says:

      This product is toxic to bees up to 3 hours after application, so you should not apply to any trees in flower. Proper timing of pesticides greatly reduces the risk posed to non-target pollinators. To my knowledge gypsy moth feeds on mostly trees that are wind pollinated, so impact to honey bees shouldn’t be an issue. Just be mindful of drift and surrounding flowering plants and you should be just fine.

  8. Kevin says:

    Our neighbor have their trees sprayed for gypsy moths and some of the overspray went on our vegetable garden, Is it safe to eat the lettuce etc from the garden?

    • The Tree Geek says:

      Hi Kevin,

      Conserve is labeled for many garden vegetables, and use in gardens. Giving the vegetables a good wash after you harvest should be all you need to do to reduce risk. The majority of vegetables listed have a, “do not apply 7 days before harvest,” with a few exceptions.
