The Spodoptera frugiperda J. E. Smith specie is a pest with a wide worldwide distribution, and in our country, it is known by the common name of fall armyworm, which affects the yield of the corn crop Zea mays L. Due to its economic importance, it is necessary to search for alternative tools to the indiscriminate use of chemical control, such as the application of biocide extracts from the Hura crepitans L plant. The objective of this study was to determine the mortality effect of three doses of the biocidal extract of H. crepitans in the control of the fall armyworm S. frugiperda in the corn crop in Imperial - Cañete. The application doses were: 37.5ml/10L, 75ml/10L and 150ml/10L, of the extract diluted in water. The variables studied were the percentage of mortality of the population, the damage expressed in degree scale, and also the plant growth (cm) and the total yield (kg) of the hard yellow maize were evaluated. A Complete Random Design (DCA) with four treatments and three repetitions (4x3) was used in this experiment. The results showed significant differences (p < 0.005) for mortality percentage, damage degree index, height and plant yield. All treatments showed a higher number of dead larvae with respect to the control. On the other hand, T3 (150 ml/10L) up to the fifth week of evaluation, was higher in all variablescompared to the other treatments, always obtaining the lowest values; for damage degree index with 1.71; for number of damaged buds with 0.31; and the highest values regarding plant height with 200.04 cm and higher yield with 10.42 t/ha.
