Summary. In herbicide studies close correlation between results given by the square quadrat method and by a point quadrat method for assessing the number and frequency of weed species was found. Marked correlations between the density obtained by the square quadrat and the cover and yield indices obtained by the point quadrat method were observed. Treatment discrimination using the point quadrat was as good as that obtained with the square quadrat and it is concluded that the point quadrat method is suitable for assessing weed control in low‐growing vegetation.
