Compare this tree with those in figs. 18 and 20. ule, in the proportion of 80 pounds sulfur, 10 pounds hydrated lime and 10 pounds lead arsenate, have not given as good results as have sprays. Oil dusts containing 5 per cent oil by weight, developed in the course of Illinois work on control of oriental fruit moth, have for seven seasons given good control of plum curculio, as shown in table 5. One of the best dusts for use on peaches for the control of curculio is made by thoroughly mixing the following ingredients: 30 pounds dusting sulfur 30 pounds dusting talc 25 pounds dusting lime 10 pounds lead arsenate 5 pounds lubricating oil of 80-100 viscosity.
