Armurox (Silicon + Peptides) Trial on Wheat -Louisiana State University

1. Armurox Wheat - Louisiana State University

2. Armurox Louisiana 1. Project goal Potential of Liquid Formulation Containing Soluble Silicon and Peptides as Foliar Source of Silicon in Wheat. Brenda Tubana, School of Plant, Environmental, and Soil Sciences Lawrence Datnoff, Department of Plant Pathology and Crop Physiology Determine the effect of foliar application of Armurox in supplying silicon to wheat. Determine if Armurox enhances wheat growth and productivity. Determine if Armurox application can minimize rust infection in wheat.

3. Armurox Louisiana 2. Methodology - Localization: 2 field studies in Ben Hur Farm & Winnsboro - Treatments : 2 N rate conditions – Si Foliar vs Radicular – Armurox & Foliar carrier - Applications ( Armurox & Foliar Carrier): 3 applications (after N, Zadoks 30 (prior stem elongation), 15DDA.

5. Armurox Louisiana 4. Results For slag and Armurox -treated week wheat, grain tended to have higher silicon content & uptake than the control or carrier-treated plots.

6. Armurox Louisiana Higher % Silicon was observed on leaf surface of wheat treated with wollastonite , slag, and Armurox indicating that there was higher number of silica bodies deposition.

7. Armurox Louisiana -The enhanced silicon nutrition of wheat brought about Armurox application early in the season did not translate into significant grain yield increases for both localizations. But… excessive rainfalls received in Louisiana in the early months of 2015

8. Armurox Louisiana Lodging was significantly reduced with Armurox applications.

9. Armurox Louisiana Certain positive tendencies in grain yield from silicon treated plots could be attributed to enhanced resistance of silicon treated wheat plants to rust during the early reproductive stage.

13. Armurox Louisiana 5. 2nd year field study results Need to have an additional site-year especially that this year was considered below average with respect to yield. -2nd field study was perform in 2016 (same protocol than in 2015). Related to disease ratings Armurox impact on leaf rust reduction was comparable with Wollastonite (Ben Hur Farm, 2016).

15. Armurox Louisiana 5. 2nd year field study results Wheat obtained higher yield for Armurox 1000 and 2000 treatment compared with the control (Winnsboro, 2016)

16. Armurox Louisiana 6. Conclusions Wheat production in Louisiana has been suffering for three consecutive years, something that we could not control such as untimely large amount of rainfall. The positive observation we had in terms of leaf rust reduction in wheat from foliar application was not fully realized in yield increases due to weather limitations.
