Eficiência e deposição da aplicação de paraquat com adjuvantes e ângulo de inclinação das pontas sobre capim-colchão, falsa-serralha e caruru

Abstract: O uso de herbicidas de ação de contato com o paraquat normalmente necessita de maior atenção com aspectos de tecnologia de aplicação em relação aos de ação sistêmica. Com objetivo de avaliar a deposição e eficiência da aplicação de paraquat associado a adjuvantes e ângulos de inclinação das pontas de pulverização no controle de plantas daninhas, um experimento foi conduzido a campo em fatorial 2x3+1, com cinco repetições. Sete tratamentos foram constituídos por duas condições do herbicida Gramoxone® (paraquat,… Show more

“…According to Mendonça et al (2007), the use of adjuvants has shown the ability to improve the spray solution by enhancing the protection and absorption of herbicides. The use of adjuvants alters the properties of the spray solution, and it can influence the formation process, the spectrum of the drops, and their behavior in contact with the target (Maciel et al, 2013). Maciel et al (2011) reported when working with adjuvants Agral ® , Silwet ® , Nimbus ® , Naturl`Oleo ® and Ag Bem ® that there was significant increase in the control of Brachiaria decumbens, B. humidicola, Setaria geniculata and Sorghum bicolor, when associated to contact action herbicides paraquat and MSMA.…”
