Selectivity of Herbicides Applied in Post-Emergence of Showy Crotalaria

Abstract: -Weed control is essential to reduce or eliminate the interference of weeds on crops. Chemical control with the application of herbicides consists of the most used method, with this aim in grain producing areas. Information about the selectivity of herbicides to C. spectabilis (showy crotalaria) are scarce, which are critical for the management of this species as a crop. One field experiment was performed to evaluate the selectivity of herbicides applied in post-emergence of showy crotalaria. The herbicides be… Show more

“…Ademais, o comportamento para estes herbicidas era esperado, já que foram considerados seletivos e potencias para a aplicação na cultura da crotalária (Braz et al, 2015, Braz et al, 2016. As misturas bentazon + diclosulam, diclosulam + diuron e bentazon + diuron aumentaram os sintomas de intoxicação em relação à aplicação isolada destes herbicidas.…”

“…Due to its pivoting root system, this plant has a high recycling capacity for nutrients, as it extracts these minerals in the deeper layers of the soil, where they are exported to the more superficial layers after the decomposition of its dry mass. It is an annual legume that has a rustic and aggressive growth, in addition to having interesting properties in the control of nematodes (Braz et al, 2016).…”

“…Therefore, the choice of the appropriate doses of these products presents a limiting factor for their use, since the purpose is the control of the weed and the reduction of its action on the crotalaria culture. (Braz et al, 2016;Timossi et al, 2011).…”

“…Na busca pela seletividade de herbicidas aplicados em pós-emergência na C. spectabilis, foi verificado que imazethapyr (79,5 g ha -1 ), flumiclorac (em aplicação sequencial), bentazon (576 g ha -1 ), além da associação entre clethodim + quizalofop podem ser utilizados para o manejo de plantas daninhas na cultura da crotalária (Braz et al, 2016).…”
