Sugars deposited on lint by late season sucking insects can make cotton difficult to spin and difficult to market. This study evaluated a lacto bacillus bacteria strain that metabolizes insect sugars under low moisture conditions. Lint with known levels of stickiness was sprayed with water containing Lasil CottonŽ and compared to untreated material after 20, 60 and 180 days in storage. Sugar quantity was estimated using a high speed stickiness detector, a minicard machine and chemical tests. Fiber properties were tested using high volume instrument and automated fiber information system machines. Ring spun yarn quality was tested using statimat and evenness machines. Less than 2% moisture was added with treatment. Consequently, no degradation in fiber quality was observed with treatment.
