NUCROP is the electrifying solution available to every farmer and contractor looking for a sustainable, easy, and innovative solution to control weeds and desiccate potatoes without any residue

How it works

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.


General principles


Field Sprayer



Volt.fuel conductive liquid

  • Key to reduced electrical resistance, low energy requirement, safety, and efficacy
  • Consists of a nitrogen and phosphate-free mineral solution and an activator
  • Does not contain chemical herbicides

Mechanical energy: 140 kW at the PTO shaft



  • Transformation to 112 kW of electrical energy
  • 16 high-voltage transformation and control units (7 kW [applicator], 2500–5000 V)


PD12M applicators

  • 16 applicators specifically designed for potato desiccation
  • Optimised for high efficacy and safety
  • Applicator width: 1.5 m


  • Up to 12 m working width
  • 6 ha/h and more depending on speed (6+ km/h)
  • Minimises damage to soil, dams, and crops



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.


  • Fast to dry down
  • Reliably efficient: does not depend on sunlight or longer dry periods

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


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 and, depending on the type of applicator, also through roots and soil. This destroys the water supply to the plants to such an extent that the plants dry out and die.

When treating with Volt.apply Nucrop and 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.

The operating speed in the field generally determines the application rate of energy per hectare. The trials in potatoes in 2020 showed that very good results can be achieved at 6 km/h. Therefore, speeds of 8-9 km/h are planned for the 2021 trials. Exact values will then result from further trials with the PD12M system.

In addition to driving, the driver must mainly take care of the speed of the tractor and the switching on and off of the sprayer and the electric unit during operation. Sprayer and Volt.apply have separate controllers in the cab. The drivers of the Volt.apply PD12M systems will be provided entirely by in 2021. Accordingly, they all have good training and experience in operation.

Experiments to control green manure under normal farming conditions have shown that electrophysical treatment had no significant effect on earthworms in the soil. The Volt.apply Nucrop process further reduces the voltage and energy requirements. Nucrop takes the issue very seriously and is conducting ongoing ecotoxicological trials in 2021 also in comparison to other methods.

The Volt.apply Nucrop process is multifunctional both systemically and as a contact agent. Therefore, the applicators or Voltfuel have to be partially adapted. The current configuration has been developed and validated for potato siccation. Nucrop will further develop this configuration and validate its effectiveness for other areas. The goal is to enable many applications with just a few configurations.

Volt.fuel is sprayed onto the plants during electrophysical treatment with Volt.apply 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. The application to the target plants can also be even more targeted.

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. Voltfuel bridges leaf hairs and irregularities on the leaves, softens wax layers and thus increases electrical conductivity. Less energy for more effect is the result.

In potatoes, an application rate of 300 L/ha 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.

Due to the phasing out of Reglone, a large gap in efficacy has arisen in potato siccation. Active ingredients such as carfentrazone and pyraflufen can compensate for this just within the permitted application range, even in favorable weather. Haulm topping and flaming cause further problems that can hardly be solved effectively, especially for seed potatoes, and may also lead to increased use of fungicides and insecticides.

Farms that are in the process of converting to organic farming often suffer particularly high weed pressure because previously chemically controlled large seed banks in the soil are suddenly less controlled. By increasing the organic content in the soil, thistles spread significantly. Nucrop is specifically developing methods to help transitioning farms control weeds as well.
