I would suggest therefore, that the Extension Service specialists in these 1 northeastern states get together and make regional recommendations on weed control practices for suburban residents. This will not only assist agents, but also be of great help to the manufacturers and distributors of materials. In conclusion 1 we in Extension, want you to feel that we are all a part of the same team. All of us wan-:"to help home gardeners make the best use of agricultural knowledge. As we continue our work with home gardeners, 1 1m sure we are acquiring a large number of satisfied customers. I know of no other group who are more grateful for our h~lp than satisfied homeowners. They frequently express sincere thanks for our unbiased opinions. Although this group is relatively new 1 I feel certain that they will be an important asset to use in our future research and extension programs for agrioultural chemicals used on and off the farm.

PROMISINGNEWCHEMICALSFORWEEDCONTROL Stanford N. Fert1S !t INTRODUCTION: The development of promising new compounds for weed control and new uses for many of the older ones continued at a rapid pace during 1960. The greater selectivity to crops, the results on previously resistant weed species, changes in application techniques, combinations of' herbicides for more effective results and even stimulation of crop growth over that expected from the removal of weed competition made 1960 an exciting year. Also to be recalled are the surprises, the compounds to which we pinned great hopes in 1959 but which failed this year. There is no doubt but what "MotherNature tl with all her variables of temperatures, rainfall, humidity, soil type, seed germination, etc., will continue to exercise a degree of skepticism on our Judgment of what looks good and/or bad. The following is an attempt to summarize some of the more promising developments for the 1960 growins season. Granulars and Combinations - New and promising developments continue in the areas of aquatic weed control, vegetable and nursery crops, brush control and air application, particularly with respect to sranular compounds. With improvements in eqUipment and formulation, increased usage can be au:ticipated. . Combinations of herbicides. show increased effectiveness over the use ·.of a s iugle compound for the control of a number of perennial weed problems. Some of these wll1 be discussed later in this ~aper. Others, includillg CIPC plus Randox, dalapon plus Dinitro and 4(2,4-00) plus dalapon have been covered by previous reports. NEWCHEMICALS WITHPROMISINGUSES: Amiben The liquid amine fo:r:mulation as a pre -emergence treatment looks very promil!ling for aDllual broad-leaved and annual grass control a.t :5 to 4 pounds per acre on carrots, black-eyed peas" lima beans, pumpkin, snap beans and soybeans. At rates of 2 pounds per acre favorable results have been obtained on cucumbers. The weed control was excellent, as· was the stand of plants, weight of plants, numbers and we:1gbt of fruits. The granular formulation has looked promising on crucifers, peppers, sweet potatoes, tomatoes and ornamentals I at rates of :5 to 8 pounds per acre. y Professor ot Agronomy, Cornell Univere ity I Ithaca, NewYork.
