Tools of the Trade: Herbicide Drift
Last week we discussed vapor drift. Physical drift, also known as particle drift, is the movement of the sprayer droplets away from the target area. It is surprising how sheets drying in the sun and herbicide drift are related. We have all witnessed the show around the nozzle with sunlight dancing in the mist. But have you considered how droplets moves? Multiple factors affect particle movement, but the two most important are droplet size and air movement.
