The use of fungicides is a practice, sometimes fundamental, to combat certain diseases caused by phytopathogenic fungi. However, many fungi can develop resistance to these chemical compounds shortly after being authorized for use, causing significant losses in crop production.

A clear example is Botrytis cinerea, causal agent of the gray mold disease in very important horticultural crops. This research line is based on verifying whether certain emerging strategies such as interfering RNA technology, the use of aptamers and the nanoencapsulation of these molecules to improve their application and efficacy in nature, could be valid and alternative sustainable solutions to control these diseases.

Today, due to current European legislation on pesticides and the European Green Deal, we need to have new molecules with fungicidal action, obtained through new plant protection tools, for inclusion in the rotations of the different control programs.

In addition, we carry out both biological and molecular studies (ARMS-PCR, LAMP) to know the presence and levels of resistance to all the fungicides that are currently authorized for the control of the gray mold disease, helping growers to make short-term decisions based on the information obtained. This avoids the unnecessary use of chemical fungicides that, in addition to doing nothing, generate resistance and do not prevent losses.
