Experimental application of 2,4-D— 2,4-dichlorophenoxyacetic acid—to Bartlett pear trees for the control of drop at Davis was first made on July 3, 1947, to determine the effectiveness of the material in retarding drop, the necessary and critical concentrations and the influence upon ripening and storage quality.
