Coffee Science, 2020 Coffee litter and the rain that occurs after the application of pre-emergence herbicides impact on their leaching and weed control effectiveness. The objective of this study was to evaluate the leaching and control effectiveness of indaziflam, applied on coffee litter, and under simulations of different amounts of rainfall.

Controle de Urochloa plantaginea com herbicidas residuais e performance agronômica de dois cultivares de feijoeiro [PDF]
Revista Brasileira de Herbicidas, 2014 O objetivo deste trabalho foi avaliar os efeitos da utilização de herbicidas residuais, aplicados em pré-emergência do feijoeiro, sobre a redução da infestação de plantas daninhas e o desempenho agronômico da cultura. Foram realizados dois experimentos a campo, sendo que um tinha o cultivar UFT -06 (Grupo Carioca, ciclo curto e porte ereto) e o outro o

Genetic Diversity and Population Structure of Brachiaria Species and Breeding Populations
Crop Science, Volume 57, Issue 5, Page 2633-2644, September–October 2017., 2017 Several apomictic Brachiaria (Trin.) Griseb. (syn. Urochloa P. Beauv.) species are commercially important tropical forage grasses, but little is known about the interspecific diversity and population structure within this genus. Previously published genus‐level Brachiaria phylogenies were conducted with few genotypes and contradicted well‐established ...
