    Q
    When do I use the Dormant Spray? What month, time and how much for scales on fruit trees?
    You say dormant, what is it? When the tree stops having fruit or while the tree has very small oranges? I have scales on the tree now.
    A
    Dormant seasons are the times of the year when trees are not actively growing. This will vary from region to region and by type of tree. We recommend that you contact your local cooperative extension office and ask for information on the type of tree you are treating and the time of year it is dormant (almost all trees are actively growing now in the USA). We can tell you that Bonide All Season Horticultural and Dormant Spray Oil can be used anytime of the year and is labeled for use on orange trees to control scale insects. Be sure to read and follow the Bonide All Season Horticultural and Dormant Spray Oil product label to be sure it fits your needs.

    Q
    Dose Dormant Spray Oil work on Bagworms over the Winter or only before breeding in the fall?
    Will this sufficate the eggs of bagworms if I spray in early Fall?
    A
    The Dormant Spray Oil is actually not labeled for bagworms so we cannot recommend it be used for this pest.  The eggs are actually very protected by the bag they are layed it so no chemical will actually be able to kill them in this stage.  The best time to treat is in the Spring when the larvae hatch and before they form the bag as an adult.  Please take a moment to read over our Bagworm Control article.

    Q
    Is it okay to use this product as an anti desicant?

    We are unsure of what you mean by anti-dessicant. However, the Dormant Spray Oil is a suffocant and works by suffocating the labeled insects.

    Q
    Should I get rid of bagworms myself?
    I have a large row of arbor vitae and 3 died last summer due to bagworm infestation. Do I pay a company $240 (dormant oil and 3 follow up treatments) or is it easy enough to do myself. The trees are about 12 feet tall.
    A
    You certainly can do your own pest control using professional products. Bagworm treatment on Arborvitae starts with treating in June or shortly after egg hatch. We would recommend the Hi Yield Dormant Oil.

  • Asked by John from Hendersonville, Nc

    Q
    What is a good defense against rhododendron stem borer that would work this time of year?
    A
    Control of  rhododendron stem borer is difficult because the adults move around freely, often laying eggs under plants on which they have not chewed.  By the time root damage is noticed, it is too late to save the plant. Cutting off and burning infested stems as soon as they are noticed in the growing season is recommended for control. Dormant oil spray like Hi Yield Dormant Oil Spray can be applied to kill overwintering nymphs prior to new plant growth. Summer oil, like Fertilome Liquid Carbaryl can be used in mid-June or early July for the crawlers.

    Q
    Would Dormant Spray oil be the best for Wolly Adelgid on my Hemlock hedges?
    If so would I use the 3 oz/gal?
    A

    For Hemlock Wooly Adelgids we typically recommend Dominion 2L

    When using Dominion 2L as a soil drench for Hemlock Woolly Adelgids you should use 0.2 fl. oz. (3 to 6 mL) of Dominion 2L per inch of trunk diameter (D.B.H.) diluted in 1 pint - 1 gallon of water per inch of trunk diameter.    The amount of water that is used will vary depending on soil conditions and volumes that are easy for applicators to use. The minimum amount of water that should be used is 1 pint per inch of trunk diameter but you may use 1 quart -1 gallon of water per inch of trunk diameter. Denser soils such as clay do not accept water as readily, so the lower volume of water is suggested.  Since sandy soils can accept more water, using the higher volume of water is preferred. After the soil drench has been applied you should water it in with at east 1/2 inch of water. Note: Water simply acts as a carrier and it is important that even distribution of the product is achieved. Thus, more water may be used if the applicator feels runoff will not occur and proper penetration of the root zone is achieved. Insecticides applied to the soil are taken up by the roots and trans-located throughout the tree or shrub. Root/soil drenches offer the advantage of requiring no special equipment to apply (other than a bucket or watering can). However, surface layers of organic matter, such as mulch or leaf litter, can bind the insecticide and reduce uptake. Before applying drenches, it is important to remove or pull back any mulch or dead leaves so the insecticide solution is poured directly on the mineral soil. It is also important to keep the soil around the tree or shrub moist for the next 7-10 days after applications to encourage uptake.
