Abstract:Weekly measurements of twig growth in inches and leaf growth in area were made throughout the growing season, on tagged twigs on several apple trees. Foliage was colIected at each of the dates of measurements and analyses made for lead arsenate. These results are correlated with the increase in leaf area and twig growth. At the end of the spraying season the leaves on the tagged twigs were collected, separated into groups according to the dates when they first appeared and analyses made for lead arsenate. These results are correlated with the growth of leaf area.
