    • Disclosed are novel methods for a protecting or preserving wood, wood composites and other cellulosic materials, and in addition, disrupting the feeding behavior and growth cycle of termites, wood-borers and other insects, by applying certain compositions thereto which contain azadirachtin carried in neem tree extracts. Disclosed are novel neem extract compositions for coating, penetrating, treating, and curing said cellulosic materials which are non-toxic and provide long active lifetimes. The compositions contain the neem extracts in combination with binding and bittering agents which enhance the effectiveness of the extracts. The compositions are made from natural, active ingredients and are water resistant. The compositions are found to be non-reactive and non-toxic to vertebrates and non-polluting of surrounding soils. When used as intended in non-aerobic applications, the compositions are resistant to oxidation and ozonation. In addition, when used as intended in areas without sunlight, i.e. subterranean or concealed use, the compositions are not subject to UV and photo degradation.
    • 公开了用于保护或保存木材,木材复合材料和其它纤维素材料的新方法,此外,通过施用含有印楝素的某些组合物来破坏白蚁,木螟和其他昆虫的进食行为和生长周期 树提取物。 公开了用于涂覆,渗透,处理和固化所述无毒且提供长活性寿命的所述纤维素材料的新型楝树提取物组合物。 组合物含有与提高提取物有效性的结合剂和苦味剂组合的楝树提取物。 所述组合物由天然的有效成分制成并且是防水的。 发现这些组合物对脊椎动物是非反应性的和无毒性的,并且对周围土壤没有污染。 当在非需氧应用中按预期使用时,组合物耐氧化和臭氧化。 此外,当在没有阳光的地方(即地下或隐蔽的使用)的地方使用时,组合物不经受UV和光降解。
