Product Overview

Segment II Herbicide is a post-emergent formula that effectively kills troublesome weeds in ornamentals, naturalized areas on golf courses, and residential and commercial landscapes.

The active ingredient quickly penetrates plant tissues and rapidly provide systemic activity so that it can start working immediately. It features a flexible formulation so you can combine it with other compatible herbicides and adjuvants for more extensive treatment. It rainfast within an hour so the effectiveness will not be reduced in case of rain. Available in a 2.5-gallon jug.

DIRECTIONS FOR USE:

Restrictions and Limitations:

  • DO NOT use treated vegetation as pasture, hay, feed or forage.
  • Avoid direct or indirect contact with any desired grass crop unless otherwise recommended on the Segment II label.
  • DO NOT apply Segment II with another pesticide where one component of the tank mix is incompatible with additives, surfactants or oil adjuvants.
  • DO NOT use recirculating sprayers to apply Segment II.
  • DO NOT apply to grasses or ornamental crops under stress such as stress due to lack of moisture, hail damage, flooding, herbicide injury, mechanical injury, or widely fluctuating temperatures, as unsatisfactory control and injury may result.
  • DO NOT apply through any type of irrigation equipment.
  • Avoid using Segment II with adjuvants at temperatures above 90degrees Fahrenheit and relative humidity is at or above 60%, or any time the temperature exceeds 100 degrees Fahrenheit, as injury may result.
  • Only use Segment II on centipedegrass and fine fescue. Application to other turfgrass species will result in unacceptable injury or plant death.

Mode of Action:

Sethoxydim, the active ingredient in Segment II, is a graminicide which inhibits the enzyme acetyl CoA carboxylase (ACCase), resulting in cessation of fatty acid synthesis which is essential for new growth. Segment II rapidly enters the targeted grass weed through the foliage and translocates throughout the plant. Whole plant death occurs over approximately 3 weeks. Sethoxydim is classified in Group 1 by the Weed Science Society of America (WSSA) and Group A by the Herbicide Resistance Action Committee (HRAC).

Resistance Management:

Weed resistance to ACCase-inhibiting herbicides (Group 1), is known to occur, and populations of resistant biotypes are known to exist. Resistance management practices include:

  • Following labeled application rate and weed growth stage recommendations
  • Avoiding multiple repeat applications of herbicides with the same mode of action
  • Using tank mixes and sequential application with other effective herbicides possessing different modes of action

Application Instructions:

Applications (aerial, broadcast, band or spot spray) can be made to actively growing grass weeds at the rates and growth stages listed in the label unless instructed differently in Crop-specific Information. The most effective control will result from making postemergence applications of Segment II early, when grass weeds are small. Delaying application permits weeds to exceed the maximum size stated and will prevent complete control.

DO NOT apply when conditions favor drift from the target area or wind speed is greater than 10 mph.

Ground Application (Broadcast):

Apply with properly calibrated ground equipment in sufficient water per acre to provide uniform spray distribution (between 5 to 50 gallons spray solution per acre or 1 to 10 pints per 1,000 square feet). Apply Segment II using 30 to 60 psi. If weed or crop foliage is dense, use a minimum of 20 gallons of water and 60 psi.

Spot or Small Area Application:

Segment II can be applied using tank-type sprayers, backpack sprayers, high-volume equipment with handguns, or other suitable nozzle arrangements. Prepare a solution of
Segment II in water according to Table 3 or Table 4 on the label.

DO NOT make spot treatments in addition to broadcast treatment.

Mixing Instructions for Backpack and Pump-up Type Sprayers:

  • Fill a clean spray tank 1/2 full with clean water
  • Add required amount of Segment II
  • Cap sprayer and agitate to ensure adequate mixing
  • Uncap sprayer and add appropriate amount of adjuvant (COC or MSO) or additive
  • Cap sprayer and agitate again to ensure adequate mixing
  • Finish filling tank to the desired level

Apply spray mixture directly on sporadically occurring susceptible weeds. For best results apply on a spray-to-wet basis. Follow up applications may be made if necessary.

Environmental Hazards:

This is toxic to aquatic organisms. For terrestrial uses, DO NOT apply directly to water, or to areas where surface water is present, or to intertidal areas below the mean high water mark. DO NOT contaminate water when disposing of equipment washwater or rinsate.
