New sources of natural crop protectants are needed. Unlike conventional chemical crop protection products that are based on a single compound, plants produce combinations of compounds that in synergy are active against invasive pests.

Screening for bio pesticides

An important way of searching for bio pesticides is screening naturally occurring bioactive compounds in plants, in our case with the use of plant extracts. Plant-pest interactions are chemically mediated by secondary metabolites.

Botanical pesticides, are generally pest specific and are relatively harmless against non-target organisms including humans and thus easier to register at the CtGB. They are generally better biodegradable and less harmful to the environment.

Examples of crops described in the literature with plant protection and herbicidal activity:

Chrysanthemum Lilium Orchideae Gerbera Freesia Crocus˙

Together with an international consortium of public-private research partnerships led by CSIC (Spain) we have obtained and characterized a new bio insecticidal extract derived from Crocus sp. corms, tepals and leaves.

The patented extract exhibited potent anti feedant activity and will be used for insect-pest control (Leptinotarsa decemlineata, Spodoptera littoralis, Myzus persicae).
