Agronomic alert: The corn earworm overcame resistance and attacks on corn lots are appearing in Santa Fe

Among the companies providing services, they do not want to talk too much about the issue for more than obvious reasons: “The seed does not get dirty.” But the INTA - again the INTA - is there for these things and has just made public a more than worrying situation: due to the misuse of Bt technology by producers, who did not set up the corresponding refuges, the populations of corn earworms have acquired resistance to the transgenic event and therefore attacks are being recorded on corn plots in northern Santa Fe.
