Despite investigations of new nematode control methods, little is known about the action mode of resistance induced involving control of Pratylenchus brachyurus. Thus, this work aimed to evaluate the activity of defense-related enzymes in the control of P. brachyurus in maize treated with acibenzolar-S-methyl (ASM). For this, maize seedlings were submitted to four treatments: plants inoculated with P. brachyurus and treated with ASM (IT), inoculated and not treated (INT), not inoculated and treated (NIT) and not inoculated and not treated (NINT). Ten days after germination, the plants were sprayed with ASM and inoculated (800 specimens plant-1). Each five and two days after treatment (DAT), in two different experiments, the plants were collected for analysis of the enzymatic activity of... view more»
