Procedure for a collaborative study of leaching from CCA-treated timber in the sea
1988 - IRG/WP 4143
As a follow-up to the collaborative IRG/COIPM marine trial of CCA and CCB preservatives, a further trial is proposed with the objective of measuring the degree of leaching of CCA components from three timber species at marine sites in Malaysia and the U.K.. Details of the planned procedure are given....

N-tritylmorpholine as a potential marine wood protectant against teredinids and pholads - A preliminary evaluation
1983 - IRG/WP 497
The molluscicide, N-tritylmorpholine, is effective in eradicating certain fresh water snails, the intermediate hosts in the transmission of schistosomiasis in man. This preliminary study shows that N-tritylmorpholine is also active against wood-boring marine mollusks. Fine sapwood impregnated with this morpholino compound was not damaged by teredinids or pholads while exposed at two marine sites i...

Evaluation of some polyurethanes as protective marine coatings for wood
1985 - IRG/WP 4115
Several polyurethane formulations were evaluated in the marine environment as possible replacements for Irish felt used on U.S. Navy minesweepers as a marine borer barrier between the main wooden hull and an outer, wooden sheathing which covers it. Pine panels coated with the candidate materials were tightly juxtaposed with untreated pine baitwood to simulate the hull/sheathing configuration, the ...

Test of N-tritylmorpholine in combination with synthetic pyrethroids against marine borers in tropical Australia and Panama
1991 - IRG/WP 4168
Test blocks ol Pinus sylvestris sapwood were pressure impregnated with white spirit solutions of N-tritylmorpholine, either alone or in combination with permethrin, deltamethrin or cypermethrin. They were exposed in the intertidal zone at Mourilyan Harbour, North Queensland, Australia and subtidally at either end of the Panama Canal. After 5 months' exposure at Naos Island at the Pacific ...

An initial evaluation of the environmental impact of potential marine biocides
1978 - IRG/WP 441
Pilings and other structures in the marine environment are protected primarily by impregnation with creosote alone, or in combination with coal tar or waterborne preservatives such as copper-chrome-arsenate. Some of these materials are considered as possible ecological hazards and face an uncertain future; perhaps newly developed treatments to replace these conventional ones will pose different pr...

The antifungal efficacy of Guayule resin
1987 - IRG/WP 3429
The Naval Research Laboratory is evaluating the non-rubber-producing portion of guayule (Parthenium argentatum) resin as a protectant for wood in terrestrial and marine service. This study phase, in collaboration with the universities of Arizona and Mississippi State, evaluates the resin's fungicidal worth. Resin-impregnated pine sapwood was exposed to brown rot fungi (Gloeophyllum trabeu...

The evaluation of non-rubber extractives from the guayule plant (Parthenium argentatum Gray) for pesticidal worth
1986 - IRG/WP 4125
The resin obtained from the guayule plant (Parthenium argentatum Gray) of the southwestern United States is a potentially imporant domestic source of natural rubber, however only about 20 percent of the extractives from the plant produce this material. An effort is underway to find marketable uses for the remaining non-rubber extractives, and the Naval Research Laboratory is evaluating this resin ...
