| description |
The objective of this work was to evaluate the effects of applying glyphosate and chlorpyrifos alone or in combination on Octolasion cyaneum, Porcellio scaber, and Brassica napus. The experimental unit consisted of a PVC cylinder filled with 3 kg of soil into which 10 individuals of O. cyaneum, 8 of P. scaber and 10 seeds of B. napus were introduced. The treatments were: glyphosate alone (960, 4800 and 9600 g ha-1), chlorpyrifos alone (576, 2880 and 5760 g ha-1), and their combinations, following a completely randomized experimental design with six replications. The bioassay was performed in a chamber at 20 ± 2 °C, with a 14 h light: 10 h darkness photoperiod. At 28 days after application, the number of live O. cyaneum did not vary between treatments (p = 0.307). The highest percentages of damage to O. cyaneum were found with chlorpyrifos (p = 0.021). The proportion of O. cyaneum in the depth range only differed between 0-10 cm (p = 0.031). At 5, 7 and 28 days after application, the highest percentage of dead P. scaber was obtained with chlorpyrifos (p < 0.05), with values higher than 70%. Regarding B. napus, significant differences (p < 0.001) between treatments were found both in emergence percentage 7 days after sowing, and in total number of plants, plant height, fresh weight and dry weight percentages 28 days after sowing, the highest values obtained with chlorpyrifos. In conclusion, chlorpyrifos, alone or with glyphosate, caused lethal effects on P. scaber and sublethal effects on both O. cyaneum and B. napus. |

In conclusion, chlorpyrifos, alone or with glyphosate, caused lethal effects on P. scaber and sublethal effects on both O. cyaneum and B. napus. Se evaluó el efecto individual y en mezclas de glifosato y clorpirifos sobre Octolasion cyaneum, Porcellio scaber y Brassica napus. La unidad experimental consistió en un cilindro de PVC con 3 kg de suelo y se introdujeron 10 individuos de O. cyaneum, 8 de P. scaber y 10 semillas de B. napus. Los tratamientos fueron: 960, 4800 y 9600 g de glifosato ha-1, 576, 2880 y 5760 g de clorpirifos ha-1 y sus combinaciones. El diseño fue completamente aleatorizado con 6 repeticiones y el bioensayo se realizó en una cámara a 20±2 °C y con un fotoperiodo de 14 h de luz: 10 h de oscuridad. A los 28 días después de la aplicación (DDA) de los agroquímicos, el número de O. cyaneum vivas no varió entre los tratamientos (p = 0,307). Los porcentajes mayores de daños sobre O. cyaneum se hallaron con clorpirifos (p = 0,021). La proporción de O. cyaneum en el rango de profundidad solo difirió entre 0 - 10 cm (p = 0,031). A los 5, 7 y 28 DDA, el porcentaje mayor de P. scaber muertos se obtuvo con clorpirifos (p < 0,05), hallándose valores superiores a 70 %. El porcentaje de emergencia a los 7 días después de la siembra (DDS) como el porcentaje de plantas totales, altura, peso fresco y seco de las plantas de B. napus difirieron entre los tratamientos a los 28 DDS (p < 0,001), obteniéndose los valores mayores con clorpirifos. Clorpirifos, solo o en mezclas con glifosato, causó efecto letal sobre P. scaber y efectos subletales tanto sobre O. cyaneum como en B. napus. Os efeitos individuais e mistos de glyphosate e chlorpyrifos em Octolasion cyaneum, Porcellio scaber e Brassica napus foram avaliados. A unidade experimental consistiu de um cilindro de PVC com 3 kg de solo e foram introduzidos 10 indivíduos de O. cyaneum, 8 de P. scaber e 10 sementes de B. napus. Os tratamentos foram: 960, 4800 e 9600 g de glifosato ha-1, 576, 2880 e 5760 g de clorpirifos ha-1 e suas combinações. O delineamento foi inteiramente casualizado com 6 repetições e o bioensaio foi realizado em câmara a 20 ± 2 ° C e com fotoperíodo de 14 h de luz: 10 h de escuridão. Aos 28 dias após a aplicação (DAA), o número de O. cyaneum vivo não variou entre os tratamentos (p = 0,307). As maiores porcentagens de dano em O. cyaneum foram encontradas com clorpirifos (p = 0,021). A proporção de O. cyaneum na faixa de profundidade diferiu apenas entre 0 - 10 cm (p = 0,031). Aos 5, 7 e 28 DAA, o maior percentual de P. scaber morto foi obtido com clorpirifos (p <0,05), encontrandose valores superiores a 70%. A porcentagem de emergência aos 7 dias após a semeadura (DAS) como porcentagem de plantas totais, altura, massa fresca e seca de plantas de B. napus diferiu entre os tratamentos aos 28 DAS (p <0,001), obtendo os maiores valores com clorpirifos. Em conclusão, clorpirifos, sozinho ou com glyphosate, causou efeito letal em P. scaber e efeitos subletais em O. cyaneum como em B. napus.
