Rigger: adjuvant for increased herbicide efficacy

Rigger is a low viscosity methylated seed oil (MSO) that is easy to mix, forming a stable homogeneous emulsion with a wide range of plant protection products. Rigger improves coverage of the target surface and increases penetration through the outer waxy cuticle, increasing herbicide efficiency.

How was Rigger developed?

Our adjuvants are developed alongside universities, research institutes and independent scientists. Independent trials, financed significantly by our parent company Frontier, produce clear, reliable results. We work alongside agronomists to ensure we understand the key issues being experienced on the farm, by crop and region. Our adjuvant technologies and products are designed and rigorously tested to address these issues and support farmers in maximising productivity in crop production.

What is an adjuvant?

Typically used alongside crop protection products, adjuvants are designed to enhance the efficacy of spray products. They do this by adhering them to the plant surface, giving a more even spray coverage, slowing drying time of spray products to increase absorption, reducing UV degradation or even to lower the pH as a buffering agent. Intracrop has developed a range of adjuvants that work in a range of ways, specifically designed to be partnered with crop protection products. 

Why are adjuvants used with crop protection products?

In short, adjuvants enhance the effectiveness of crop protection products and increase the efficacy of active ingredients. Adjuvants in agriculture work in a variety of ways: by adhering them to the plant surface, giving a more even spray coverage, slowing drying time of spray products to increase absorption, reducing UV degradation or even to lower the pH as a buffering agent.

Frequently asked questions

What is Rigger and how does it differ from other adjuvants?

Rigger is a low‑viscosity methylated seed oil (MSO) that forms a stable emulsion and enhances herbicide efficacy by improving coverage and penetration through waxy cuticles, particularly useful with difficult-to-wet targets.

How does Rigger improve herbicide performance?

It enhances spray retention and absorption by altering droplet characteristics, ensuring the active ingredient reaches the plant surface more effectively and maximising uptake.

Which herbicides is Rigger best suited for?

Rigger is particularly suited for use with Fop, dim (dinitroanaline), DEN, and sulfonylurea (SU) herbicides, including sugar beet herbicides and potato desiccants.

How should Rigger be added to the spray tank?

Always add Rigger last, ensuring all other products are fully dispersed and with continuous agitation to maintain the stability of the spray mixture.

Is Rigger more effective than other adjuvant oils?

Yes, Rigger has demonstrated superior performance in field studies, offering up to 45% better coverage and 50% better penetration compared to alternative adjuvant oils.

Can Rigger be used on edible crops?

According to Great Britain and Northern Ireland’s adjuvant regulations, Rigger can be applied on edible crops at specified rates and intervals. Always adhere to statutory label instructions for safe use.

Can Rigger be used beyond herbicides?

While it’s optimised for herbicide performance, Rigger may also support other foliar treatments, particularly where penetration through waxy cuticles is needed. Compatibility testing is recommended.

How does Rigger contribute to environmental stewardship?

By improving spray efficacy and reducing drift or runoff, Rigger supports more efficient active ingredient use, helping reduce chemical usage while maintaining effectiveness.

What is the formulation concentration of Rigger?

Rigger contains a high concentration of oil (840 g/L rapeseed fatty acid esters) making it an effective deposition and penetration enhancer.

How was Rigger developed and field-tested?

Rigger was developed with leading universities, research institutes, and independent agronomy scientists. Its performance is backed by independent trials, many supported by Frontier, ensuring reliable, farm-relevant results.
