124 PEDIGREE OF A PESTICIDE. D.R. Spak and N.M. Hamon, Bayer Environmental Science, Research Triangle Park, Raleigh, NC. ABSTRACT This presentation takes the audience through a 10 to 20-year journey from the discovery through to the commercialization and growth of a new agrochemical. It attempts to explain the dramatic consolidation in the industry, addressing costs, competition, the challenging regulatory environment, patents and intellectual property and the influence of biotechnology on the market. The presentation shows the science and complexity of identifying a new active ingredient and the exhaustive testing required to get it to the market place. Also addressed is the innovation required to keep older chemistry competitive. 106
125 HOW GOLF COURSE SUPERINTENDENTS VIEW NEW HERBICIDE COMPOUNDS. S. Zontek, United States Golf Association, Glen Mills, PA. ABSTRACT One of the basic prerequisites of a good golf course is a weed-free turf. It is basic. The game of golf is played on grass, not weeds. Golfers (usually) cannot distinguish between most weed grasses growing in the desired turfgrass stand. They can distinguish between weeds like crabgrass (Digitaria sanguinalis (L.) Scop.), goosegrass (Eleusine indica (L.) Gaetn), dandelions (Taraxacum officinale Weber), dallisgrass (Paspalum dilatatum Poir) and Poa annua, during the period of the year when it produces seedheads. Therefore, golf course superintendents are interested in controlling the weeds. Golf course superintendents tend to embrace new herbicide chemistries. They understand that a well conditioned golf course is a positive reflection on their work and their programs. The reverse is also true. No golf course superintendent likes complaints as in not being able to find a golf ball that lands in the rough due to a thick mat of clover or the seed pods from dandelions. Also, grassy weeds present uniformity as well as playability issues in roughs. Right or wrong, today’s golfers desire roughs which are consistent. Weeds in rough present a stand of grass that can (and is) inconsistent both in terms of appearance and playability. Therefore, controlling weeds is a priority for golf course superintendents for practical as well as perceptive reasons. A well presented golf course, free of weeds with a healthy stand of turfgrass, is pleasing to most golfers. Equally, the reverse is true. This presentation will be an attempt to discuss the latest herbicide chemistries on how they are being used by golf course superintendents in the Eastern Transition Zone and Mid- Atlantic Region of the United States. Herbicide compounds to be discussed are the latest suggested usage for the older chemistries of broadleaf and annual grassy weed controls as well as how superintendents are using the latest chemistries of weeds including the ALS inhibitors. 107
