1966 Herbicide Damage to Crops Swan Hill District: Damage reported at South Woorinen, Woorinen, vinifera, Wood Wood, Goodnight, Koraleigh…

“Extensive damage, presumable due to 2,4-D has occurred this year to horticultural crops, particularly sultanas, in the Swan Hill district, including substantial loss of yield in some places… There is little doubt that the bulk of the damage can be attributed to aerial spraying of cereals within a few miles of the affected vines… The conclusions drawn suggest that aerial spraying should be discouraged within four miles of sultanas and currents during their growing period and that the Murray River is not necessarily an adequate buffer… NSW Department of Sprays.
