ASSESSING HERBICIDE SELECTIVITY AND EFFICACY WITH LOGARITHMIC SPRAYERS

Field test of the effect of adjuvants on the potency of a 28.5% nicosulfuron mesotrione mixture was done with a logarithmic sprayer on barley. Barley Tolerates mesotrione, but it seems to antagonize the effect of nicosulfuron. The use of logarithmic sprayers is relatively inexpensive compared to normal field experiment designs. The Effective Dose (EDx) levels can be assessed depending on the objectives of the experiment, e.g., tolerance of crops, and appropriate weed control. We illustrate how we can summarise logarithmic field experiments in a simple and succint ways.
