The Cleancrop™ Brassica System is a simple weed management system which eradicates a range of key problem weeds, commonly found in brassica crops throughout New Zealand. These weeds compete with your brassica crop decreasing yield production. It’s time to take back control of your crop this spring.

Simplified Weed Control

The CleancropTM Brassica System is an integrated weed management programme that offers excellent control of key problem weeds in brassica.

brassica cultivars with excellent agronomic performance

Cleancrop brassica cultivars containing the CleancropTM Brassica System technology have been bred from the very successful Plant and Food Research Ltd/PGG Wrightson Seeds joint breeding programme.

Forgae Innovations Ltd. in addition to their tolerance to Telar herbicide, each cultivar, depending on species has improved forage yield, palatability, disease and insect tolerance. 

Best Practice Guide and stewardship plan

The CleancropTM Brassica System must be implemented on-farm in accordance with best Practice Guide and stewardship plan. Developed by PGG Wrightson Seeds and DuPont, this programme is designed to optimise the on-farm performance of the CleancropTM Brassica System.


Note: The CleancropTM Brassica System of Cleancrop brassica seed plus Telar herbicide should not be used in the crop rotation in the year prior to planting fodder beet or potatoes due to sensitivity of these crops to Telar.

The CleancropBrassica System can be used where a simple weed control programme is required that controls

a wide range of historically difficult-to-control weeds in brassica crops.
