Australia proposes to approve DowDuPont’s GF-3301 Herbicide (300 g/L florpyrauxifen-benzyl in a suspension concentrate formulation) for the control of certain grass and broadleaf weeds in rice and the active ingredient Rinskor™ (florpyrauxifen-benzyl).
Florpyrauxifen-benzyl belongs to the arylpicolinate group of synthetic auxin herbicides. Florpyrauxifen-benzyl mimics the effect of a persistent high dose of the natural plant hormone auxin, causing over-stimulation of specific auxin-regulated genes which results in the disruption of several growth processes in susceptible plants. The product has the disrupters of plant cell growth mode-of-action. For weed resistance management, the product is a Group I herbicide.
GF-3301 Herbicide will be applied to rice crops for post-emergent or in-flood control of grass and broadleaf weeds via boom spray or SCWIIRT (Soluble Chemical Water Injection In Rice Technique) rig using a steel wheeled tractor, all-wheel drive motor bike or aircraft. It will be applied at rates of 100 mL/ha (30 g a.i./ha) for foliar application or 150 mL/ha (45 g a.i./ha) for in flood application.
Florpyrauxifen benzyl is registered in US, China, Korea and Chile. Registrations are pending in other rice producing countries such as Columbia, Brazil, Argentina, Spain, Italy, Turkey, Egypt, India, Thailand, Vietnam, Indonesia and Japan.
