Beauveria bassiana 203

How does Beauveria bassiana 203 work?

After inoculation with Beauveria bassiana 203:

1. Spores of this fungus come in contact with the skin (cuticle) of susceptible insects, and they germinate.


2. Then, they adhere and secrete substances that degrade the cuticle, allowing them to penetrate the insect.


3. Once the fungus is inside the insect, it multiplies, consuming the insect's nutrients. As a result, the insect dies from starvation, toxins produced by the fungus, and/or invasion of all its organs.


4. Finally, the fungus emerges to the surface and produces more spores, helping it disperse Bb203 to the other insects.² ³

Practical case: Red palm weevil (Rhynchophorus ferrugineus) control

The following shows an approved test on Canary Island date palm trees, carried out in Elche (Alicante, Spain) in an area where the red palm weevil is present. Canary date palm trees with a 1-meter stipe were studied under field conditions.
A dose of 1200-1800 g/tree was applied 3 times per year.

Number of treated plants: 401.
Number of untreated plants: 588.
Date of the first application of the product: 5/1/2011.
Date of the the second application of the product: 1/5/2011.
Date of the the third application of the product: 6/9/2011.

Result: after three applications, the treated palms showed an 82% decrease in the red palm weevil population.

Does Beauveria bassiana 203 have other applications?

Beauveria bassiana 203 has been found to be highly effective against a number of pests of agricultural interest.

Thus, we are working to develop additional applications and formulations of this new active substance, adapted to different farm, crop, and pest management practices.
