Efeito da redução de luz na seletividade a herbicidas e rendimento de grãos do trigo

Abstract: A redução da radiação solar incidente na superfície terrestre pode alterar o comportamento vegetal e a seletividade de herbicidas. O objetivo deste trabalho foi avaliar a seletividade dos herbicidas bentazona, iodosulfuron-methyl-sodium e o rendimento de grãos do trigo, em condições de redução de luminosidade em diferentes estádios fenológicos da cultura. Foram conduzidos dois experimentos, o primeiro (I) em condições controladas e o segundo (II) a campo. Nos dois experimentos foram avaliadas variáveis no trig… Show more

“…Among the herbicides with the most significant potential for preharvest desiccation, those with limited translocation, popularly called contact herbicides, have a more significant advantage due to their rapid defoliant action than the others . In addition, limited translocation reduces the herbicide’s potential to migrate to the seed through symplastic transport pathways.…”

“…In addition, limited translocation reduces the herbicide’s potential to migrate to the seed through symplastic transport pathways. For example, when applied to leaves, systemic herbicides can translocate and accumulate in the seed. , This scenario can be unfavorable due to possible damage to the seedling generated from these contaminated seeds, impairing the initial establishment of the crop or even reducing the harvested productivity.…”
