Resumen
"GM (genetically modified) corn with the CrylAb. mC3Aand Vip3A20 protein of Bt ( Bacillus thuringienesis ) and itsrespective isoline as control with andwithout chemicalcontrolfor corn carworn werw used in thisresearch. Fusarium corncob damague was lower on GM corn with (12.5 %and without (25.7%) insecticide treatmenas compared witthe isoline that had40.3% and 83.1 % of damaged corncobs with (12.5)and without (25.7% insecticide treatment as compared with the isoline that had 48.3% with (3.2% ) and without(6.3%insect control.respectively, Ustilago maydisseverity was also lower on Bt corn finding 0.07% and 0.25% damageon treatments withand without insect control as compared the isoline that shwedan 11.6% and a 41.4%smut rotwith and without insecticidetreatment. respectively. The authors conclude that GM corn resistantto Helicoverpa zea prevents damageby the pest, eliminating the entrance patway for Fusarium sp. and Ustilago maydis."
