The bulletin reports on the first four years of the Maine Potato Ecosystem Project, a long-term, multidisciplinary study of alternative crop management strategies. The study site is a 15-acre tract on the northern boundary of the University of Maine's Aroostook Farm in Presque Isle, Maine, divided into 96 main plots that are grouped into four blocks. Each block is an area where soil survey data show similar soil characteristics. Thus, given the same production inputs, the crop output is expected to be the same on each plot within a block. Within each block there are 24 plots to which the …

B837: New Approaches To Chemical Control Of White Pine Weevil Damage, John B. Dimond, Richard L. Bradbury
Bulletins
There has been little recent research on control of damage by the white pine weevil, and available insecticides have been few and have become obsolete. Tests in Canada suggested that the insect growth-regulating chemical diflubenzeron was effective, and we have successfully repeated those tests in Maine using several formulations of Dimilin and several ground application systems. Aerial trials have not succeeded; the probable reasons for their failure are discussed. We present a general description of the weevil and its damage, approaches to control of damage, and specific recommendations for use of ground applications of Dimilin, which has recently become registered …
