| description | The objective this work was to evaluate the effect of microbial and chemical insecticides on the fall armyworm Spodoptera frugiperda in the development initial phase of crop corn. The work was lead in the experimental area of the State University of Mato Grosso do sul, in Cassilândia (MS) city. The treatments had been: 1) control; 2) fipronil; 3) thiametoxan; 4) Beauveria bassiana (0,5 kg of p.c/ha), 5) Beauveria bassiana (1 kg of p.c/ha), 6) teflubenzuron and 7) spinosad, in the doses and recommended way of application. After the tenth second after the emergency of the plants (DAE), had been day applied the treatments in foliar spraying (PF), being evaluated to the 2, 9, 15 and 21 days after the application (DAA), the number of small caterpillars (lesser that 1,5 cm) for parcel in 20 showed plants. The applied results show that teflubenzuron and spinosad in PF to the 12 DAE had been most efficient (71 and 83% respectively). The microbial¢s insecticides had not differed significantly from the chemical insecticides in the percentage of plants attacked for the pest and the 15 and 21 DAA. |
