Nettle extract controls black bean aphid in broad bean
- Broad bean (Vicia faba) /nettle extract (Urticae spp.)/black bean aphid (Aphis fabae)
- Effective control of the black bean aphid. Compatibility of the nettle extract with beneficial insects, allowed the parasitoid Aphidius colemani to move into the crop providing an additional aphid control.
- Technical result: effective bean aphid control respecting beneficial insects resulting in a synergyistic control.
- Economic result: biological solution at the same efficacy and longer term than chemical treatment
- Sustainability (ecological, social and economical) Gains:
-
- Reduction of the reliance on chemical pesticides
- Compatibility with beneficial insects enables synergistic bean control
- Increased biodiversity enabling long term pest control and resilient cropping systems
- Reduction of the reliance on chemical pesticides
-
- Enables worker and consumer health and safety
- Promotes more sustainable residue free bean production, better accepted by the public
- Enables worker and consumer health and safety
-
- Through its growth stimulating effect, the nettle extract supports specialized smallholder farmers’ livelihood and value generation
- Improvement of financial viability by reduction of man and tractor hours as the nettle extract is applied through fertigation
- Through its growth stimulating effect, the nettle extract supports specialized smallholder farmers’ livelihood and value generation
