People and pets should stay out of areas treated with Pendulum 3.3 EC Herbicide during application and at least until the product is dry. Often the primary reason for this is to make sure that walking around on the wet application does not disturb it, rather than because of health concerns. Pendulum 3.3 EC herbicide is not meant to be harmful to birds.
Pendulum 3.3 EC Herbicide should be watered within 24 hours to 30 days after the application.
It is not recommended to use a hose end sprayer when applying Pendulum 3.3 EC. You may use a backpack sprayer for larger areas. Per the product label, "Low-pressure (e.g. 20 to 40 psi) sprayers are recommended." Pendulum 3.3 EC - 2.5 Gallons is oil based but should not clog sprayers when mixed as directed on the label. Agitating the mixture well before and during application can help it stay suspended. We do carry many professional grade backpack sprayers that could be used to apply it.
Pendulum 3.3 EC Herbicide should be applied when soil temperatures are idealy between 55 and 65 degrees. We recommend using a soil thermometer to check the soil temperature or you can contact your Master Gardener with the County Cooperative Extension Office for their recommendation on the best time to apply pre-emergents in your area.
There is also Syngenta’s GreenCast Website which is a great resource to check the soil temperature in your area. Please go to www.greencastonline.com, click Soil Temperature Maps then type in your city/zip code under Location Search.
Per the product label Pendulum 3.3 EC Herbicide may be applied at planting or to established trees. When making application at planting, it is important that silt closure be achieved to prevent direct contact with tree roots or being washed into the rood zone or root stunting may occur.
It is recommended to keep applications Pendulum 3.3 EC Herbicide stay outside of the dripline of trees to avoid contact with any exposed roots. Roundup Pro applications would be limited to very carefully spot treating the weeds there directly only and avoiding any contact with the tree and roots so broadcasting is not an option as is needed with the Pendulum 3.3 EC.
Pendulum 3.3 EC Herbicide is not labeled for use in grazing pastures.
An alternative herbicide would be Prowl H20 that contains the same active ingredient and labeled for pastures where animals graze. Please review the Prowl H20 product label for more information.
Pendulum 3.3 EC Herbicide is not labeled to prevent dallisgrass and is tolerable and labeled for safe use on bahiagrass so would not control it either. Dimension would be a pre-emergent for preventing dallisgrass, but there is no pre for bahia. It is usually best to spot treat this and reseed with your desirable turf, depending on what that is.
Pendulum 3.3 EC is not specifically labeled for switchgrass therefore we cannot say it would fully prevent it from germinating. This product can also be used for preemergent control around tolerant shrubs listed starting on page 10 of the product label. Please review the tolerant shrubs to ensure this application will not injure your desirables.
Please contact BASF for 800-526-1072 for further assistance with your specific treatment.
Pendulum 3.3 EC Herbicide should be applied when soil temperatures are below 65 degrees. To check the soil temperature in your area, please go to greencastonline.com. Under Resources, you will click “Soil Temperature Maps,” and then type in your city or zip code under “Location Search.”
Pendulum 3.3 EC Herbicide should only be applied to established landscaped areas/ornamentals. It is recommended to wait a few months to plant in the areas previously treated and it is advised to rotate soil.
Pendulum 3.3 EC Herbicide will not control established or actively growing weeds, rather it is a pre-emergent that stops susceptible weeds from germinating and growing, eventually causing them to die before they ever emerge from the soil. Please see our Post Emergent Herbicides for products that will kill weeds that have already emerged in your lawn.
Pendulum 3.3 EC is not labeled for use on raspberry plants. If you are looking for a post-emergent weed killer to use around raspberries, you could use Hi-Yield Grass Killer Post-Emergent Herbicide instead. If you need a pre-emergent herbicide, Fertilome Over the Top II would be a great option.
Pendulum 3.3 EC applied in October may prevent weeds germinating in May when used as the highest rate listed on the label. You want to be sure that there is enough “drizzle” to water the product in ½ inch within 30 days of application. For the best timing advice it would be recommended to contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region.
The only product that can help repair a lawn that too much herbicide such as Pendulum 3.3 EC is a liquid charcoal and unfortantely we do not carry one. Over watering the area could help to push it down into the soil more but that depends on how soon after application this is done. You can try reaching out to the manufacturer to see what they would advise. BASF can be reached at 800-777-8570. You will need to wait at least 4-6 months to reseed/sod the area after application.
Pendulum 3.3 EC - 2.5 Gallons would be best as a broadcast application since it is a pre-emergent herbicide not a post, so will not kill anything actively growing. Common names include buffelgrasses, sandburs, and sand spur for weeds that are stickers, so you do want to be sure the weed has been correctly identified.
Unfortunately, that is proprietary information on the Pendulum 3.3 EC product, but the active ingredient pendimethalin is not what causes it to be yellow. There is an actual yellowing agent that does that. We recommend using Pendulum AquaCap if you want that same active ingredient that does not contain the yellow agent in it.
Pendulum 3.3 EC - 2.5 Gallons is a pre-emergent that prevents weeds from growing by creating a barrier in the soil itself. It does not affect any currently emerged weeds, and mowing would not effect the application. That being said you should be sure to remove any thatch layer or grass clippings if any on the lawn so the product can better contact the soil and be sure to water in as directed on the product label. It is recommend to avoid mowing 2 days before or 2 days after applying herbicides so that there is not extra stress on the turfgrass.
Pendulum 3.3 EC will leach into the soil if the product has not settled firmly or been watered in. The label advises that when using Pendulum 3.3 EC care must be taken that soil or planting mixes have settled firmly following any new plantings so that any cracks in the soil would not allow direct contact with Pendulum 3.3 EC.
Pendulum 3.3 EC can be applied to landscape beds prior to mulching. It will be able to absorb into the soil underneath the mulch. It should not be applied to newly transplanted plants until they are rooted successfully. You will also want to use the lowest rate on annuals. It should be applied in March-May and again in Aug-Nov for the best control with cool season turfgrass. It is important to apply pre-emergents just before the soil reaches 55+ degrees, just before the seeds begin to germinate in the soil.
