Nematode resistant green manure

An effective green manure crop

BRACO has a very fast plant development after seeding. Consequently BRACO has i high ability to take up nitrogen from the former crop, thus preventing nitrate leaching from the soil. This retained nitrogen is available for the successive crop and the need for bagged nitrogen fertiliser is reduced. BRACO also adds organic material to the soil, improving the soil structure and humus content.

An effective nematode killing effect

BRACO white mustard has the capacity to redusing the beet nematodes in the soil by interfering in the life circle of the nematodes. Beet cyst nematodes are able to develop on all types of beets, spinach, cabbage, swedes and oil seed rapes. The only way to control nematode attacks is to use crop rotation and green manure to reconstruct the soil.

Excellent for biofumigation

When BRACO is in early flower stage, the crop can be chopped down and worked into the top soil. The chopped up crop will release glucosinolates which act as a biofumigant to kill nematodes, insects and even weed seeds. Studies have shown that BRACO, when properly managed, will have the same effect on nematodes as a chemical fumigation, at a fraction of the cost.
