Warning disclaimer: Agrociencia (written with only one word) is a Mexican journal. Our five decades tradition and background information is linked to Colegio de Postgraduados (www.colpos.mx). English authors (who perform searches by adding "journal" to their keywords) have been misled via spam mailing to a forged site, by adding just one letter (the O) to COLPOS lawful domain. Those spam mails have been reported to hijacking and predatory lists since January 2020 and all along last year. Unfortunately searching utilities like Google allow visibility to sites according to the number of random visits. Thus, to everyone interested we inform that, this one is AGROCIENCIA only lawful and secure website. Manuscripts should be submitted here and only here. No payment or any further process is made through this interface; only submissions.
