Synergistic effects between 2-HPNO, Irganox 1076 and EDTA on the inhibition of wood degradation by Coriolus versicolor
2004 - IRG/WP 04-30331
The efficiency of 2-hydroxypyridine-N-oxide (2-HPNO) as wood preservative has been investigated. As shown using classical experiments as well as using response surface methodology, the efficiency of 2-HPNO as wood preservative is strongly improved in presence a chelator like EDTA and/or of Irganox 1076 an industrial antioxidant. In these conditions, wood preservative efficiency of the mixture the ...

Investigation of new wood preservation formulations based on synergies between antioxidant, 2-HPNO and Propiconazole
2006 - IRG/WP 06-30401
Wood degradation by fungi is a complex phenomenon taking place in part through oxidative reactions involving many oxidizing agents like free radicals and hydroperoxide. In order to develop novel and more environmentally benign preservative systems, mixtures of Propiconazole and antioxidants with different stabilization mechanisms were investigated to detect possible synergies allowing to reduce th...

Efficacy of chitosan in combination with GRAS (Generally Recognised As Safe) compounds as a potential wood preservative
2007 - IRG/WP 07-30414
In vitro studies were undertaken to evaluate the synergy between chitosan and selected GRAS (Generally Recognised As Safe) compounds against two sapstain fungi Sphaeropsis sapinea and Leptographium procerum. Bioassays performed on nutrient medium suggested that some of the GRAS compounds tested including sodium benzoate, potassium sorbate and ascorbic acid had a synergistic effect when combined w...

Potential synergy between natural product extracts for limiting fungal decay
2009 - IRG/WP 09-30495
Natural products often exhibit tremendous potential for inhibiting various microorganisms when they are tested in petri dish tests, but perform poorly when tested in vivo. The failures can often be attributed to a lack of broad spectrum activity against the range of organisms present in a natural environment. One method for overcoming this challenge is to use extracts from a number of sources with...

The Concept of Copper and Boron Synergy: Why Copper Naphthenate and Borates are a Couple Made in Heaven
2013 - IRG/WP 13-30622
Fungicides are often combined for four basic reasons:(1) to widen the spectrum of the fungicidal activity in which to broaden the spectrum of activity, (2) to exploit additive and synergistic activities between actives, and the activities are increased and thereby reducing the needs for the higher loadings of the active in the substrate, (3) to delay the resistance of one of the actives in the for...
