Growth, development, and chlorophyll indexes of glyphosate and glufosinate-tolerant maize under herbicide application

Glyphosate, glufosinate, and atrazine do not affect the growth development of glyphosate glufosinate-tolerant (RR2/LL) maize; however, results are less consolidated for these herbicides applied in mixtures. The aim present study was to evaluate effects post-emergent application glyphosate, atrazine, alone mixtures, on RR2/LL maize. treatments consisted (1080 g acid equivalent [ae] ha-1), glufosinate (500 active ingredient [ai] (2000 + control (without application). experiment carried out two locations under greenhouse conditions with different maize hybrids. Crop injury variables agronomic performance (height, stem diameter, chlorophyll indexes, fresh dry weight shoot, root weight, total weight) were evaluated. Herbicides or binary mixtures did cause major damage. However, three associated some situations might result detrimental
