NUCROP is being developed by Nufarm and CROP.ZONE. It is based on a unique hybrid herbicide concept that combines a conductive liquid called Volt.fuel with electro-physical weeding. This technology is an alternative and complementary solution to chemical-based weed control. Application of Volt.fuel allows for optimised, safer electrical energy management as it uses much less power than other electric weeding technologies and raises agronomic efficacy.
Initially, NUCROP will focus on potato desiccation in Germany, France, the UK, and Benelux in 2021. We will be expanding the range of applications (greening control, weed control) and our geographic scope to include other countries from 2022 onwards. In bringing this solution to market, our aim is to reduce the rising pressure on farmers due to the phase-out of ever-more chemical herbicides and the need to replace them effectively – without compromising on product quality or climate protection and while conserving soil life and quality. We intend to launch NUCROP at prices that are competitive with current alternatives, enabling us to achieve fast growth.
Volt.fuel conductive liquid
Mechanical energy: 140 kW at the PTO shaft
In the 2023 season, potato growers can participate in the Early Adopters program. Access to the technology is simple: NUCROP relies on the usual distribution channel partners. In this season, machines will be available in Benelux, France, Germany, Poland, UK, & several other EU countries where we will carry out extensive test and practical programs. Development and testing are ongoing for other applications such as intercropping and pre-seeding, inter-row weed control (industrial or perennial crops) and post-harvest use. We expect that further applications in addition to potato desiccation will be available from 2024.
The unique NUCROP combination is highly efficient at controlling weeds with no residue compared to the chemical alternatives, and offers better efficacy and crop safety than mechanical interventions. Application of the conductive liquid and actual control of the weeds with electrical voltage are carried out in a single step.

Nufarm is one of the world’s leading developers and manufacturers of crop protection solutions and specialty seeds. For more than 100 years we’ve been finding more effective ways to fight disease, weeds, and pests to increase the yields of our customers’ crops, by turning world-leading scientific breakthroughs into local solutions.
Throughout its history, Nufarm has been creating new solutions to respond to farmers’ changing needs and yet there has perhaps never been a more exciting time to be part of the agricultural industry. Farmers around the world are being called on to produce more food with fewer resources and are increasingly at the forefront of global efforts to reduce the impact of humanity on our precious ecosystems. The products and solutions that Nufarm provides, both in conventional chemistry as well as biological products, play an important role in helping farmers feed more people while using natural resources such as land and water more efficiently.
With manufacturing and marketing operations based in Europe, Australia, New Zealand, Asia, and the United States, Nufarm employs more than 2,500 people, all of whom make a vital contribution to the company’s reputation for quality products, innovation, and first-class marketing and technical support. You can find more information at www.nufarm.com.
CROP.ZONE was established in 2019 by a highly experienced team of agtech experts with decades of experience in the field. Today, CROP.ZONE’s hybrid herbicide solution is in active use in the field, demonstrating its efficacy in weed management, cover crop burn-down, and pre-harvest desiccation. CROP.ZONE offers electrophysical solutions to combat weeds and manage pre-harvest desiccation, providing farmers with an alternative tool against the backdrop of tighter regulatory requirements and societal expectations.
The innovative patented CROP.ZONE solution can replace a significant part of today’s chemical herbicide use and close the gaps resulting from reregistration. It provides a competitive alternative for weed management, thus contributing to yield optimisation and farm profitability while helping to achieve sustainability goals. CROP.ZONE’s solutions give the company a strong footing in the future agriculture market. You can find more information at www.crop.zone.
How does the NUCROP technology work?
Electric current with a voltage of 2000 to 5000 V is generated by the tractor with a PTO generator and special high-voltage units. Via special applicators, the current is passed through plants.This destroys the water supply to the plants to such an extent that the plants dry out and die.
To what depth are the roots destroyed?
When treating with NUCROP or long-range applicators (LRA), desiccated roots, especially the taproot of thistles to a depth of about 15 cm have been observed so far. The depth of destruction also depends on the type of applicator, soil moisture, plant species and the amount of energy applied.
What is the driving speed in operation?
The operating speed in the field generally determines the application rate of energy per hectare. The trials in potatoes in 2020-2022 showed that very good results can be achieved at 3-6 km/h. The application speed always depends on the density of the crop.
What influence does NUCROP have on soil life?
In 2021, a large ecotoxicological study was conducted by an independent institute. The application of the 96 kW electrophysical desiccation had no adverse effects on the natural soil fauna communities until about 6 months after application. Accordingly, the NUCROP-System showed no significant acute or long-term effects on earthworms, springtails and oribatid mites.
In which other segments, apart from potato desiccation, can the NUCROP system be applied?
The applicators of the NUCROP system are adapted for individual applications. The current configuration has been developed and validated for potato desiccation. NUCROP will further develop this configuration and validate its effectiveness for other areas. Potential other segments could be intercropping, pre-seeding or post-harvest use.
What is Volt.fuel?
Volt.fuel is a conductive liquid and is sprayed onto the plants during electrophysical treatment with NUCROP. As with chemical herbicides, it is the key formulation that allows the active ingredient electric current to work effectively and minimizes the amount needed. As a result, the working width and treatment speed can be increased.
How does Volt.fuel work?
The active ingredient must always reach the site of action as effectively as possible. Therefore, the current must penetrate the contacted leaves with as little loss as possible and then destroy the water supply in stems and, in some cases, roots. Volt.fuel bridges leaf hairs and irregularities on the leaves, softens wax layers and thus increases electrical conductivity. Less energy for more effect is the result.
What is the application rate per ha?
In potatoes, an application rate of 150 L/ha of water and 10 L/ha Volt.fuel has proven to be very good. Depending on the environmental conditions (haulm largely wilted, dew on the plants, etc.), a change may be appropriate in individual cases. Since the stream acts systemically, only wetting of the areas touched later is necessary. This reduces the dependence of the application rate on the total biomass.
Why is NUCROP focusing on potatoes?
The application of plant protection products shortly before harvest is increasingly viewed critically. NUCROP therefore offers the option of reducing or dispensing the use of herbicides for desiccation as a pre-harvest use in potatoes.
Can the NUCROP-System also be used in organic farming?
Yes, the formulation of Volt.fuelBIO will also make it possible to use the system in organic farming from 2023 on.
