Speeding the Drying of Alfalfa Hay with Fusicoccin1
- Neil C. Turner22
Fusicoccin, a wilt toxin produced by the fungus Fusicoccum amygdali Del., was sprayed onto alfalfa (Medicago sativa L.) 3 hours before cutting. Under constant environmental condition in the laboratory, the shoots treated with 10-5 M fusicoccin solution dried to a moisture content of 40% (dry weight basis) in half the time of the controls. In the field the drying time to a moisture content of 22% (dry weight basis) was reduced from 54 to 46 hours; thus the hay could be safely stored after 3 days instead of 4 days. The fusicoccin also reduced losses by respiration. Rainfall probabilities for Connecticut suggest that use of fusicoccin would prevent damage by rain on 15% of the days suitable for haymaking. The results also suggest that fusicoccin will be more beneficial when drying conditions are poor.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
