WebCry1F corn was first commercially planted in 2003 in the United States, Canada, and Puerto Rico, 2005 in Argentina, and 2009 in Brazil. To date, practical resistance of S. frugiperda with field control problems to Cry1F corn has widely occurred in Puerto Rico, Brazil, Argentina, and the southeast coastal area of the U.S. mainland. The surge of ... WebDue to the extensive use of Bt crops, practical resistance of S. frugiperda to Cry1F corn (TC 1507) with field control problems has widely occurred in Puerto Rico, Brazil, Argentina, and the mainland United States. Analyzing data generated from decade-long studies showed that several factors might have contributed to the wide development of the ...
