Most Effective Biofumigant for Cauliflower

Farmers can now rely on cauliflower in decreasing the incidence of bacterial with on potato.

This was proven in the undergraduate study titled “Validating Biofumigation for the management of Ralstonia Solanacearum Affecting Potatoes” conducted by Crisanto Guilabo, BS Plant Pathology of Benguet State University (BSU).

Guilabo showed that application of brassicas can effectively reduce incidence of bacterial wilt, with cauliflower being the most effective. Other biofumigants tested included broccoli, cabbage, Chinese cabbage, sunflower and untreated soil.

In the study, brassica tissues were shredded and mixed with the soil and left to biofumigate for two weeks.

The used of cauliflower showed the lowest disease incidence of 14.34% and was followed by broccoli, sunflower, cabbage and Chinese cabbage.

The study also showed that biofumigation can be used as an option in an integrated and long-term management of bacterial wilts disease.

Meanwhile, other means of applying the said biofumigants must be considered to lessen production cost. Types of crops, production systems, geographic locations and seasonal cultural management practices must also be considered.
