A faster-acting silage inoculant has been introduced by Corteva Agriscience in time for silage operations this summer.
Pioneer brand 11G22 Rapid React (RR) is for use on high dry matter grass, wholecrop cereal and lucerne silage crops. Compared to the original 11G22, the Rapid React product includes an additional new strain of the bacteria Lactobacillus buchneri, which ensures treated silages are aerobically stable much faster after ensiling.
“These combination inoculants contain multiple strains of bacteria – predominantly homofermentative strains of lactic acid producing-bacteria, which quickly lower silage pH, and for high dry matter silages Lactobacillus buchneri, which suppress growth of undesirable yeasts and moulds that can lead to heating,” explains Pioneer’s Andy Stainthorpe.
“The strain of Lactobacillus Buchneri in 11G22 was effective at reducing silage heating, but these forages were not ready for feeding until six weeks after ensiling. The 11G22 RR will produce silages that are aerobically stable earlier than this.
"With forage stocks still low following summer 2018’s drought, early feeding of this year’s silage is being considered on many units,” he adds.
The latest inoculant will also reduce shrink losses during feed-out and ensure that silage remains cool for longer when the silage is exposed to air.
“With so many different types of silage being made, it is important to choose the right inoculant for each one,” says Mr Stainthorpe.
“The trend towards producing drier silages automatically leads to greater potential for mould and yeast growth. So treating with an effective and crop-specific product is critical to achieving good fermentation and minimising losses.”
