Higran Turf Miticide Ref #CHIGR-1

Higran is a preventative or early curative miticide, treating nymph and adult couch grass mites.

Higran is used as the second application in a two-step process and is rotated with alternate chemistry from a different mode of action groups.

Higran is a ‘pro-insecticide’ meaning the active ingredient goes through a conversion process post application, to enter a biologically active state. Insecticidal activity occurs immediately (paralysis) with control usually occurring 5-7 days after application.

Key benefits of Higran Turf Miticide

• An entirely different mode of action (MOA) to manage and/or prevent resistance build up
• Strong contact, translaminar and vapour activity meaning pests on the underside of leaves not directly contacted are still treated equally well
• High degree of selectivity to target pest – causes rapid paralysis and feeding cessation
• Longer duration of residual control compared to traditional chemistries registered for couch mite control
• One part of a two-step strategy to better manage Couchgrass Mite in turf

Application Timing and Rate Variation

Higran can be used as a preventative or early curative miticide when treating nymph and adult couch grass mites. Ideally Higran is used as the second application in a two-step process and is rotated with an alternate chemistry from a different mode of action (MOA) group. Higran is a ‘pro-insecticide’ meaning the active ingredient goes through a conversion process post application to enter a biologically active state. Insecticidal activity occurs immediately (paralysis) with control usually occurring 5-7 days after application.

For example, in the case where environmental conditions have become conducive to mite activity and early symptoms of damage (e.g. witches broom) has been noticed on a couch grass sward, apply Gymnast Turf Miticide first at the rate of 2 L/ha to knock the population down quickly and limit early damage. Follow this with an application of Higran at 500mL/ha, 10-14 days later for residual control of up to 4 weeks. This combination treatment should be considered a 6 week program in total and can be repeated if environmental conditions and pest pressure are sustained.

Strong adherence to this rotational program is paramount for responsible chemical use and good resistance management. For full application details, please consult the product label.
