Orthene 97 Spray Insecticide

Orthene 97 Spray Insecticide is used for insect pests on trees, ornamentals and turf. Its powerful active ingredient, Acephate, works in two ways. First, Orthene 97 Spray kills insects on contact, then it penetrates plant tissue for local systemic control. No worries about rain or irrigation because plants will absorb this product within 24 hours. This product is safe to be applied without a mask due to low vapor pressure, low oral and dermal toxicity, and volatility. Orthene 97 Spray is for non crop area ant control, sod farms, outdoor and perimeter spray, trees and shrubs, greenhouse and outdoor floral crops, ground covers, and golf courses.



For use on turf, use limited to sod farms and golf courses, except when applying to mound or spot treatment for fire ant and harvester ant control.

Do not apply with low pressure handwand except for control of fire ants as a mound treatment and when used on ornamental trees, shrubs and floral plants grown for non-agricultural or non-commercial use.

Not for indoor residential use. For greenhouse use, use is limited to commercial greenhouses for use on ornamental, floral and foliage plants and tobacco (floatbed application).

This product and its degradate are highly toxic to bees exposed to direct treatment on blooming crops or weeds. Do not apply this product or allow it to drift to blooming crops or weeds while bees are actively visiting the treatment area.

QHow many gallons can a can of Orthene 97 Spray Insecticide make?
I have bag worms.

AOrthene Spray 97 Insecticide is not for residential use. The amount of product that the can will make will depend on the application. We cannot find any systemic insecticides that are labeled for bagworm control. Acephate 75 was labeled for bagworm control but due to new EPA regulations they were forced to change the label and exclude using the product as a systemic. You should also note that systemic products are not the best choice if you already have damaging pests present because the products can take weeks or even months to translocate through large trees from soil applications. The best treatment for bagworms is a direct foliar spray with Talstar. Talstar P is the #1 recommended product for bagworm control. TalstarP is known to have a very low toxicity for mammals making it safe to use around people and pets. Please visit the Talstar P product page where you can review the product label as well as the MSDS. Talstar P applications should start in April and continue monthly through June for bagworm control. Be sure foliage is sprayed thorughly to the point of runoff to achieve adequate coverage.

QCan I spray Orthene 97 on termites?
I found some termites on my bathroom walls and I am Taking the walls down this coming Friday 4/18/14 can I spray Orthene 97?


Orthene 97 Spray Insecticide is used for insect pests on trees, ornamentals and turf and is not labeled for residential use or for termites. 
You will need to determine what kind of termite you have for us to direct you on the best treatment method. If you have drywood termites, you could drill holes into the galleries and inject a product like Termidor Foam to expand and eliminate the colony. You will only be injecting the foam into the studs and around where the activity is, not filling the entire wall void. It would be hard to determine exactly how many cans you would need withouth knowing where you are primarily seeing activity. If you have subterranean termites, you will need to do a trench treatment around the home to eliminate the colony in the ground with a product like Termidor SC. Termidor SC will last in the soil for at least 10 years to both eliminate your current termites and prevent any new ones from entering the home. The Termidor SC trench treatment would kill the existing termites in the wall of your home as well, but you could always do a spot treatment with the Termidor Foam to help speed up the process along with the trench treament. You can see how a homeowner can treat there home for subterranean termites in our article "How To Do A Termite Treatment"

QDoes Orthene 97 work on Leaf Cutter ants if so whats the ratio for 1 gal of water?

AOrthene 97 is not labeled for the eradication of leaf cutter ants. Leaf cutter ants can be a difficult pest to get rid of. The colonies are large and the ants make their own food so poison baits only have limited effects on this species of ants. According to several university websites, Maxforce Complete Bait Granules containing hydramethylnon are some what effective, though they will usually eliminate only about 30% of a large colony in one treatment and will need to be reapplied several times.  Deltagard granules is one of the only products actually labeled for leaf cutter ants. The product label recommends treating the mound directly and lightly watering the granules in. Again it may take several treatments to get the desired results. We also recommend contacting your local cooperative extension office to see if they have any recommendations for products that have worked for other people in your region.

QCan Orthene 97 be washed out of soil in a pot or ground?
My neighbor sprayed my soil by my vegetable pots with Orthene while I was out of town. Now I am worried about eating my vegetables.


We would not recommend consuming any edible plants that have been sprayed with Orthene 97 Spray Insecticide, except for those listed on the product label and at the indicated Pre-Harvest Interval. You may use a product such as D-Tox Flowable Charcoal to absorb some of the pesticide in other areas where it may have been applied.

QCan Orthene be used on staghorn and footed ferns without causing damage?
I have fern scale on staghorns and footed ferns. Can Orthene 97 be used without causing damage to ferns? Also, how to mix? How much/gallon of water? Thank you.


Orthene 97 Spray Insecticide is NOT specifically labeled for scale on staghorn ferns. We recommend that you contact your local cooperative extension office for a recommendation. They can determine if the fern has scale or fungus. Excessive moisture and poor air circulation could also play a part in the planted areas and they will determine if this is also a factor. Most scale treatments for staghorn fern applications will be the use of horticultural oils and/or insecticidal soaps.

QIs this product safe to use on orchids (vandas)?
when my vanda blooms the flower looks burned and it doesn't open. They told me that it must have some type of fungus so they recommended the orthene insecticide.


Orthene 97 Spray Insecticide is used for insect pests on trees, ornamentals and turf not labeled for fungus diseases. Please look at our Fungicide Page for a list of fungus products. You will also want to know the type of fungus you are treating for. We recommend contacting your Master Gardner for assistance in identifying the type of fungus you are treating for. After identifying the disease, we will be more able to help you choose the right product.

QMy outdoor lantanas have mealybug. If Orthene 97 is in pellets, how do I make it into spray, by what ratios?
I'm completely confused to how to determine how many pellets to use to get a good mix for 1 gallon of ready to use spray? My lantanas and Orchids are outside, btw. Also, aphids are destroying my Crepe Myrtles. Black soot everywhere.

AOrthene 97 is not a pellet formulation. This formulation is more like a powder. Orthene 97 is not labeled for congtrollign mealybugs on ornamental plants. If you would liek to use a product that works systemically you may want to consider using Dominion 2L which is labeled for mealybugs as well as aphids.

QWhat would be the correct ratio of Orthene 97 to water for a handheld sprayer to control Thrips?
Wanting to apply on the top leaves of Ornamental Ficus Nitida?

AThe Orthene 97 Spray Insecticide is not labeled for thrips on ornamentals so we are unable to provide mixing instructions.  We do carry a product called Adonis 2F which is labeled for use on ornamentals for thrips as a foliar spray or soil drench.
