The germination percentage (normal seedlings) was determined at 14 days after sowing on paper [, Together with the germination test, the FGC was performed five days after sowing to determine the seed vigor [, Finally, in the germination test, the seeds considered dormant (“hard” in the soft compression with tweezer) were also evaluated by the tetrazolium test (TZ), to confirm their viability as described by Brazil [, The viability of ryegrass seeds was assessed by TZ. ; formal analysis, A.H.S., O.A.S., D.C.S.

In addition to negatively impacting production, also affecting the quality of ryegrass seeds, it further emphasizes the importance of the practice for integrated and sustainable management. In order to ensure the correct application at the development stage and to standardize the size of plants in a growth stage, a mechanical mowing was performed, sectioning the plants and allowing a remnant of approximately 30 cm.

Deutsche Saatveredelung AG is one of Germany’s leading plant breeding companies in agriculture focusing on breeding, production, advisory services and sales. Westerwold Ryegrass (Lolium multiflorum west.) In the case of paraquat, the reduced dose should be used regardless of the ryegrass reproductive stage. ; Hsiao, A.I. Previous research has evaluated the ryegrass seed production with glyphosate, glufosinate and paraquat application, but studies comparing them with other active ingredients are lacking. Barros, A.F. ; Cesco, V.J.S. Similar results were found in wheat with the application of paraquat in a milky to pasty grain stage. ; Martins, D.; da Costa, A.C.P.R. Catalogue of seed plants of the West Indies Smithsonian Contributions to Botany 98: 1-1192. Schwartz-Lazaro, L.M. In addition, the application of 2,4-D (670 g ha, The TSW was significantly reduced with the herbicide iodosulfuron-methyl and the trinexapac-ethyl regulator, with 23% reductions in the dose of 2.5 g ha, The viability of the seeds produced was performed by TZ, which indicated that the herbicide iodosulfuron-methyl (2.5 and 5 g ha, In the germination test, iodosulfuron-methyl significantly reduced the germination and vigor of ryegrass seeds, regardless of the dose for vigor and there was a greater reduction in germination at the highest dose (5 g ha, All herbicides and plant growth regulators sprayed at the fruit development stage decreased seed production, to a greater or lesser extent (, The most significant reductions in seed production compared to the control occurred with the application of paraquat (97%), ammonium glufosinate (91%), glyphosate (89%), clethodim (83%) and iodosulfuron-methyl (77%). With the information obtained in this study, it can also be stated that seeds added to the seed bank after a spray treatment would, therefore, be less competitive in subsequent crops as was observed in the applications of paraquat, clethodim and ammonium glufosinate, whose ryegrass seeds had vigor and germination minors. ; Agostinetto, D.; Schaedler, C.E. and L.V. ; Farias, H.D.S. Madafiglio, G.P. Lolium multiflorum seeds were collected from an old-field community lot (>2 ha) of the Inland Pampa region (Carlos Casares, Province of Buenos Aires, Argentina, 34°06′S, 60°25′W) and showed >85 % frequency of Neotyphodium endophyte infection (Vila Aiub et al., 2005). those of the individual authors and contributors and not of the publisher and the editor(s).

For iodosulfuron-methyl, the effect of the dose is indifferent in relation to seed production, but to reduce the quality of seeds in the flowering stage the recommended dose is more efficient.
