Resumo: | Glyphosate-resistant sourgrass is difficult to control, particularly when perennial, and strategies that improve the control efficiency against this grass and preserve the useful life of graminicides are warranted. Therefore, the present study aimed to answer the following questions: (i) Does fractionating the doses of ACCase inhibitors improve the control of perennial sourgrass? (ii) Does alternating the chemical groups cyclohexanediones (DIMs) and aryloxyphenoxypropanoates (FOPs) improve the control of perennial sourgrass, and does the order of their application affect sourgrass control efficiency? (iii) Does the addition of glyphosate to ACCase inhibitors improve to the control of perennial sourgrass resistant to 5-enol-pyruvyl-shiquime-3-phosphate synthase inhibitors? Two field experiments (I and II) were performed in 2018 and repeated in 2019. In experiment I, the treatments included a single or fractional application clethodim + quizalofop-P-ethyl (216 + 108 g a.i. ha-1), clethodim (216 g a.i. ha-1), and quizalofop-P-tefuryl (108 g a.i. ha-1), applied in the order of clethodim followed by quizalofop-P-tefuryl and vice versa, as well as a control treatment. In experiment II, the treatments included a single or fractional application of clethodim + quizalofop-P-ethyl (216 + 108 g a.i. ha-1) and clethodim (108 g a.i. ha-1), isolated or associated with glyphosate, as well as a control treatment. In both experiments, the interval between the fractional applications was 7 days. Percentage of control, number of tillers per plant, and height of sourgrass plants were determined. Compared with the unfractionated application, the fractionation of clethodim + quizalofop-P-ethyl and clethodim increased control by respectively 20-24 and 25-30%. Fractionated clethodim has greate control, and less regrowth and height of the sourgrass plants. The order of application of the chemical groups FOPs and DIMs affected control efficiency, and better results were obtained with the application of quizalofop-P-tefuryl followed by clethodim. The addition of glyphosate potentiates the action of graminicides, particularly when fractionated, even on resistant sourgrass, with a 26% increase in efficiency and resulting in satisfactory control ( > 80%). |

Portanto, o presente estudo teve como objetivo responder as seguintes perguntas: (i) O fracionamento de doses de inibidores da ACCase melhora o controle de capim-amargoso perenizado? (ii) Alternar os grupos químicos ciclohexanodionas (DIMs) e ariloxifenoxipropanoatos (FOPs) melhora o controle de capim-amargoso perenizado, e a ordem de sua aplicação afeta a eficiência do controle de capimamargoso? (iii) A adição de glyphosate a inibidores da ACCase melhora o controle de capim-amargoso perenizado resistente aos inibidores da 5-enol-piruvil-shiquimato-3-fosfato-sintase? Foram realizados dois experimentos de campo (I e II) em 2018 e repetidos em 2019. No experimento I, os tratamentos incluíram aplicação única ou fracionada de clethodim + quizalofop-P-etílico (216 + 108 g i.a. ha-1), clethodim (216 g i.a. ha-1), e quizalofop-P-tefuril (108 g i.a. ha-1), aplicação de clethodim seguida de quizalofop-P-tefuril e viceversa, além de um tratamento controle. No experimento II, os tratamentos incluíram à aplicação única ou fracionada de clethodim + quizalofop-P-etílico (216 + 108 g i.a. ha-1) e clethodim (108 g i.a. ha-1), isolados ou associados ao glyphosate, além de um tratamento controle. Em ambos os experimentos o intervalo entre as aplicações fracionadas foi de 7 dias. Determinou-se à porcentagem de controle, o número de perfilhos por planta, e à altura das plantas de capim-amargoso. Em comparação com a aplicação não fracionada, o fracionamento de clethodim + quizalofop-P-etílico e clethodim aumentou o controle em 20- 24 and 25-30%, respectivamente. O clethodim fracionado apresentou maior controle, e menor rebrote e altura das plantas de capim-amargoso. A ordem de aplicação dos grupos químicos FOPs e DIMs afetou a eficiência do controle, e melhores resultados foram obtidos com a aplicação de quizalofop-P-tefuril seguido de clethodim. A adição de glyphosate potencializa a ação dos graminicidas, principalmente quando fracionados, mesmo sobre capim-amargoso resistente, com acréscimo de 26% na eficiência e resultando em controle satisfatório ( > 80%).UEL2022-02-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4459610.5433/1679-0359.2022v43n2p657Semina: Ciências Agrárias; Vol. 43 No. 2 (2022); 657-674Semina: Ciências Agrárias; v. 43 n. 2 (2022); 657-6741679-03591676-546Xreponame:Semina.
