    The influence of storage conditions and packaging on acetic acid generation in cellulose acetate fibers

    TATUM C.E.; WILSON S.A.; CASPER R.G.; PEARCE M.J.
    Eastman Chemical Company, Kingsport, TN, U.S.A.
    The cellulose acetate polymer used in cigarette filters is made by acetylating wood pulp with acetic anhydride. One advantage of this modified natural polymer is that it readily degrades by multiple mechanisms. While the ultimate products are carbon ...

    Strategies to control blue mold and reduce fungicide residues in cigar wrapper tobaccos

    LAMONDIA J.A.; EITZER B.D.
    The Connecticut Agricultural Experiment Station, Valley Laboratory, 153 Cook Hill Road, Windsor, CT 06095, USA
    Blue mold, caused by Peronospora tabacina, has occurred in Connecticut annually since 1996. Cigar wrapper leaves require excellent disease control, but ideally control should be achieved with low fungicide residues remaining in cured leaves. We applied ...

    Is Peronospora tabacina becoming less sensitive to dimethomorph fungicide?

    LAMONDIA J.A.
    The Connecticut Agricultural Experiment Station, Valley Laboratory, 153 Cook Hill Road, Windsor, CT 06095 USA
    Connecticut growers have concerns about potential reduced efficacy of dimethomorph (DMM) fungicide against Peronospora tabacina. Increased levels of blue mold in commercial tobacco crops despite fungicide applications over the last two seasons may be due ...

    Photodegradability testing of cellulose acetate filters – outdoor weathering vs. accelerated weathering

    STEACH J.K.; FISHER JONES D.
    Eastman Chemical Company, Kingsport, TN, USA
    Degradation testing in the laboratory is based on understanding a material’s exposure to specific environmental forces, which can play a key role in the mechanisms of degradation. Cellulose acetate filters can be degraded by various environmental forces, ...
