Laboratory and field evaluations of bio-based termiticide containing Arnica extract from Berkem Biosolutions® against native and Formosan subterranean termites
2024 - IRG/WP 24-11049
Arnica extract from Berkem Biosolutions® is a 100% plant-based ingredient, rich in active molecules, particularly polyphenols, specially adapted to the needs and challenges of termite protection. The efficacy performance of a bio-based termiticide product containing Arnica extract from Berkem Biosolutions® had been evaluated both in soil treatment and in wood protection treatment against native ...

Efficacy performance of Pea Extract as bait toxicant for termite control in Reunion Island
2024 - IRG/WP 24-11050
This study was carried out to determine the toxicity of Pisum sativum L., extract (Pea Extract) for the subterranean termite, Coptotermes gestroi (Isoptera: Rhinotermitidae). Yellow field peas (Pisum sativum L.) are particularly rich in protein. A solid-liquid hydroalcoholic extraction process was employed on the dried form of pea seeds to obtain one particular peptide PA1b (Pea Albumin 1, subunit...

Preliminary investigation of the durability and performance of 1,3-dimethylol-4,5-dihydroxyethylene urea (DMDHEU) treated aspen strandboard
2024 - IRG/WP 24-30804
Wood modification technologies are growing in popularity because of their potential to improve wood properties by permanent covalent chemical modifications rather than chemical impregnation. These features can be utilized in wood composites to help improve dimensional stability and composite resistance to fungal decay. In this study, 1,3-dimethylol-4,5-dihydroxyethylene urea (DMDHEU) was used to m...

Influence of the substitution of phenol with lignin cleavage products in phenol-formaldehyde impregnation resins for wood modification on the fungal decay resistance and impregnation depth
2024 - IRG/WP 24-30805
The impregnation modification of wood with phenol-formaldehyde (PF) resins increases the woods dimensional stability and resistance against fungal decay. However, to decrease the usage of non-renewable resources, the substitution of phenol has been a topic of scientific interest. Lignin is a currently underutilized resource with a chemical structure that contains phenolic units. For adhesive appli...

Field facility for conducting wood durability tests at LSU Agricultural Center
2024 - IRG/WP 24-41012
Efforts by Louisiana State University Agricultural Center (LSU AgCenter) to conduct wood durability research on C. formosanus and other wood-related topics, have led to establishing three field research sites to test wood products against Formosan subterranean termites (New Orleans, La), and native subterranean termites (Franklinton, LA), and to test utility poles for outdoor exposure, decay resis...
