Glyphosate spraying of forest: Blueberry and raspberry quality evaluated by sensory analysis
1985

The changes in taste, appearance and nutrient content of blueberries and raspberries as a result of spraying with glyphosate were investigated. No unambiguous conclusions can be reached with respect to changes in taste or flavour. The quality of the berries and their degree of ripeness are more important for their taste than the effect of glyphosate. Overrripe berries tend to possess a taste of mold, which masks the taste of the herbicide spray (Roundup). Blueberries andand raspberries of high quality, harvested 1-3 days after spraying, will hardly possess off-tastes. Berries harvested 5-6 days after spraying may have a tang, especially raspberries and berries of low quality. The vegetation does not change the first 1-3 days after spraying. 5-6 days after spraying the raspberries will turn lighter in colour, from red to yellow. They are then too anappetizing to be harvested. The blueberry plants drop their leaves easily, and the stem of the berry comes off with the berry when it is harvested. It is therefore easy to avoid picking the older berries, which might have a tang after the spraying. Any tang of the berries after spraying is not connected with the glyphosate content of the berrries, but might be due to other components of Roundup, possibly detergents. There is no change in nutrient content of the berries as a result of spraying
