O deslocamento de herbicidas auxínicos para o local não alvo resulta em prejuízos agronômicos e ambientais. Objetivou-se nesta pesquisa avaliar os efeitos doses dos dicamba triclopyr aplicados nas fases fenológicas V2, V4 V8 da cultura do milho. Foram testados parcelas subdivididas, no arranjo 3x5, as aplicações três milho (V2, V8) cinco cada herbicida (0; 4,8; 24; 48; 96 g e.a. ha-1). As aplic...

Growing concern about the environmental impact of ionizable and polar organic chemicals such as pesticides, pharmaceuticals and personal care products has lead to the inclusion of some in legislative and regulatory frameworks. It is expected that future monitoring requirements for these chemicals in aquatic environments will increase, along with the need for low cost monitoring and risk assessm...

Prickly sida (Sida spinosa), hemp sesbania (Sesbania herbacea), and pitted morningglory (Ipomoea lacunose) are becoming problematic weeds in many crops including corn soybean. Two separate field experiments, under non-crop conditions, were conducted at the Mississippi State University Delta Research Extension Center, Stoneville, MS to evaluate response of these eight selective herbicides three ...

Despite an extensive history of research into herbicide resistance in New Zealand maize, some aspects remain understudied. Herbicide was first detected the 1980s maize crops, with atrazine Chenopodium album L. and Persicaria maculosa Gray. Since then, has also developed to dicamba, last five years Digitaria sanguinalis (L.) Scop. populations have been reported be resistant nicosulfuron. Here we...
