Proven Performance

1 x 0.5 gal. jug of Divanem is available in a Multipak with 5 x 1 lb. jugs of Heritage Action. 
  • Controls the most troublesome nematode species including sting, root-knot and lance.
  • Powered by the trusted active ingredient abamectin, Divanem is a suspension concentrate formulation designed to move more quickly into the soil to where parasitic nematodes are found for fast, effective control at the source.
  • Helps protect roots from nematode damage and drought, which leads to more durable, stress-tolerant turf that can recover quicker from stresses like disease and aerification.
  • Allows flexible application rates and season-long rotations for effective agronomic program.
  • Divanem is available for individual sale or in a Multipak with Heritage® ActionTM fungicide.
  • When used with Heritage Action, superintendents can help manage nematodes as well as diseases and abiotic stress.

Application Information

  • No special equipment needed for application.
  • No course closures are required during or after application. Re-entry is permitted after the spray has dried.
  • Safe for use on greens, tees and fairways of all turf species.
  • Active ingredient quickly moves into the soil layer and stays where nematodes are found.
  • Turf should be wet prior to application, and a wetting agent and surfactant should be tank-mixed with Divanem. 
  • For best results, applications should be made during mornings when light levels are low and dew is present. If no dew is present, a short irrigation cycle should be run to moisten turf prior to application.

Divanem helps enhance root mass significantly.

Trial held on ’Champion’ Bermudagrass Putting Green at the Orange County National Golf Center in Winter Garden, Florida. Samples collected October 25, 2016. (Left) Untreated. (Right) Divanem (12.2 fl. oz./A) and a soil surfactant applied August 23, 2016, and September 21, 2016, and watered-in immediately with 0.2 inches of irrigation. Syngenta, 2016.

Nematode-damaged roots not only absorb less water but are also more susceptible to disease.

When combined with Heritage Action fungicide, Divanem will help improve turf quality and density as well as root growth and quality while providing enhanced biotic and abiotic stress tolerance.

Divanem helps turfgrass recover more quickly from aerification.

Treatments applied 4 times on 14-day interval beginning August 4, 2016. Divanem tank-mixed with a surfactant (6.0 fl. oz./1,000 ft2) and watered-in immediately with 0.25 inches of irrigation. Aerification performed on September 20, 2016, with 5/8 inch hollow tines on 2x2-inch centers. Young, 2016.

Divanem helps turf recover more quickly from drought.

Treatments applied 5 times on a 14-day interval prior to initiating drought stress. 37.5 and 75 gai/ha of abamectin is equivalent to 6.1 and 12.2 fl. oz./A of Divanem. Young, 2016.

Divanem provides broad-spectrum control over nematode activity.

Divanem applied to bermudagrass 4 times on 14-day interval. Data collected 12-25 days after 4th application. Crow, 2016.

Divanem helps control parasitic nematode populations to reduce root damage.

Samples collected October 25, 2016. Divanem and a wetting agent (48 fl. oz./A) applied on August 23, 2016, and September 21, 2016. Applications watered-in immediately with 0.2 inches of irrigation. Crow, 2016.
