The Science

By 2050, the growing world population will require 100 percent more food, and 70 percent of this food must come from technology that improves production efficiency. Given the magnitude of this global challenge, crop protection innovations must focus on controlling pests that have the largest impact on the world food supply. 

Rinskor™ active will enable rice farmers to address the pressing challenge of producing more food at affordable prices, while maximizing limited natural resources. With an alternative mode of action in rice, Rinskor is a unique weed management tool to support integrated weed management (IWM) and resistance management strategies for rice farmers.


How it Works

Rinskor™ active represents the latest member of the arylpicolinate family of chemistry, a unique and new class of synthetic auxin chemistry within the Herbicide Resistance Action Committee’s Group O category. Chemical substitutions resulting in the addition of an aryl ring to the pyridine-carboxylate auxin molecules yielded a new compound with significantly increased herbicidal potency that paved the way for a completely new generation of lower-dose-rate, synthetic auxin herbicides. 

Rinskor is a systemic post-emergence herbicide that is rapidly absorbed by plant foliage. In the plant’s cells, the herbicide mimics naturally occurring hormones by binding with specific auxin receptors in the cell’s nucleus. Within hours after application there is uncontrolled growth in treated plants which disrupts multiple plant processes causing a loss of normal growth function. Within hours to days, visual symptoms appear, leading to death in susceptible weed species within days to weeks after application


Herbicide use is not only essential to sustainable crop production; if wisely used, these products promote habitat preservation and species diversity by enabling farmers to maximize use of the land they are farming today.

In 2018, Rinskor™ won Green Chemistry Challenge Award presented by the American Chemical Society's Green Chemistry Institute.

Mammalian Toxicology

Rinskor™ active has a very favorable mammalian toxicity profile. Rinskor exhibits low acute toxicity with mild eye irritation being the most significant finding with the technical material as well as the formulated product. No significant adverse effects were reported in the sub-chronic, chronic, reproduction or developmental toxicity studies, nor were there any treatment-related mutagenic, carcinogenic or neurotoxic effects noted.


The environmental toxicity profile of Rinskor is highly favorable for both terrestrial and aquatic animals. Rinskor exhibits no toxicity to honey bees in either the acute oral or acute contact studies. Rinskor is toxic to susceptible terrestrial and aquatic plants.


Environmental Fate

Rinskor undergoes rapid degradation in soil and aqueous environments. The potential for off-site transport is minimized by the short half-life as well as by strong soil sorption. Degradation results in metabolites that have no biological activity. 

Rinskor is typically applied at 30 grams of active ingredient per hectare, offering a sustainable weed control method over time with a lower herbicide load. NeoEC formulations of Rinskor will offer the effectiveness of the EC formulation, with added environmental advantages.
