Fusarium in maize

What is the main fungus that affects maize productivity around the world?

Fusarium verticillioides

The main problem caused by this fungus is the decrease in the production of the plot. The early closing of the cycle and the subsequent fall of the plant makes it difficult to harvest the crop and causes significant losses in crop production.

The pathogen can penetrate the plant through wounds caused by insects or cultivation tasks, through the ground, or through the seed; infecting roots, stem and cob.

Symptoms:

The symptoms produced by this pathogen are not noticeable until the structures that produce the spores are visible.

The fungus attacks the plant stem, causing premature drying of the plant, with the consequent weakening of the plant.

In the final stages of the infection, the pith is destroyed and adjacent tissues lose their colour.

What helps Fusarium develop?

  • The presence of the fungus in the seed coming from its production process.

  • The presence of the fungus in crop production plots.

  • Problems of water or thermal stress during cultivation.

  • Nutritional imbalances in the fertilizer.

  • Growing varieties not tolerant to Fusarium.

How can it be tackled?

  • Selecting varieties tolerant to Fusarium, such as Bodega and Atlas.

  • Developing a balanced fertilizer for the crop.

  • Avoiding stress to the crop during its growth cycle.

  • Using fungicidal treatments to prevent the entry of pathogens via the root.

  • Selecting seeds with invigorating treatments that generate a more powerful and resistant root system of the plant, such as FitóCare.
