Résumé en langage clair
Two bio-based products that are known to be lethal to wireworms were tested in the field for their ability to increase the marketable yield of carrot: the fungal insect disease Metarhizium brunneum LRC112, and frass of the black soldier fly, Hermetia illucens sold commercially as Enterra Natural Fertilizer (ENF). Both products significantly increased the number of marketable carrots/ha by 46%; ENF increased the weight yield/ha by 44% and M. brunneum LRC112 by 43%. The yield increases were attributed to stand establishment, as opposed to reducing wireworm feeding on maturing roots.
Résumé
Two bio-based products that are known to be lethal to wireworms were tested in the field for their ability to increase the marketable yield of carrot: the entomopathogenic fungus Metarhizium brunneum LRC112, and frass of the black soldier fly, Hermetia illucens sold commercially as Enterra Natural Fertilizer (ENF). Both products significantly increased the number of marketable carrots/ha by 46%; ENF increased the weight yield/ha by 44% and M. brunneum LRC112 by 43%.
