Control weeds. Increase yield

The Cleancrop™ Brassica System is a crop and weed management solution all in one. 

Only Cleancrop™ combines the power of broad-spectrum herbicide Telar® and plants bred to resist it. Telar® takes care of 23 hard-to-control weeds at the time of sowing, freeing up moisture and nutrients to give your crop the best chance of maximising performance and delivering superior returns on your seed investment. Telar® cannot be used with conventional brassicas.
