The moisture content of green needles from healthy and diseased trees was determined as percentage of needle dry weight. Tip needles of current and second year shoots were found to have a significantly lower moisture content than needles from the base. Needles from unprotected shoots had lower values than bagged ones during the period January‐May. The lethal value for moisture content of current year needles was found to be 90–95 %.
