152 opportu ity to use sethoxydim annually in corn-soybean, corn-peanut, or corncotton otations. The wisdom of that would be questionable. However, rotatio of sethoxydim with nicosulfuron or primisulfuron for control of johnson rass could be beneficial in a system of continuous corn. Clearly, there w'll be a continued need for education as HTC's come into the marketp ace. HTC' may have a major impact in some cases by allowing one to expand product'on areas. An example is cotton production in the Blacklands of North Carolin. This area, characterized by organic soils, has traditionally been a major gain production region. Growers there are beginning to see cotton as a potenti lly more profitable enterprise than grain crops. Cotton grows well in these s ils, but weed control has been a major limitation because typical soil-ap lied herbicides are ineffective on soils with high organic matter. With th exception of pyrithiobac sodium, which will be available for the first t e in 1996, postemergence herbicides for broadleaf weed control in cotton ust be applied as directed sprays. Without assistance from soilapplied herbicides, the height differential necessary to direct herbicides often c nnot be obtained. The few people who have grown cotton in the Blackla ds have had to resort to hand labor to clean up the crop, which of course reatly reduces the profit potential. With bromoxynil and posteme gence grass herbicides applied to bromoxynil-tolerant cotton, growers have be n able to adequately control weeds without hand labor. When glyphos te-tolerant cotton is commercialized, growers will have additional tools f r weed management in this new production area. Vari but use the gro toleran transge for the accord! with an rotatio us benefits of HTC's may make weed management easier in some regards, of HTC's will not necessarily reduce the management skills needed by er. The grower will have to address the potential for drift to noncrops. He will have to be vigilant in identifying fields planted to ic crops so the proper herbicide is applied. He will have to be alert population shifts that likely will occur and deal with them gly. And in some cases, he will have to plan his management program eye on controlling volunteers of herbicide-tolerant crops in al crops. HTC' of corn and soybean likely will not lead to major changes in product on systems for these crops. Potentially, having the option to use somethi g such as glyphosate postemergence may increase some growers' confide ce in no-till. However, growers have already adopted no-till systems, and for the most part, weed control has not been a major limitation. Availab lity of HTC's such as glyphosate-tolerant soybean or glufosinatetoleran corn could encourage more growers to follow a total post emergence system. However, economics and time commitments necessary for other enterpr ses on the farm will drive that decision more than simply availability of HTC' • One could argue that post emergence systems are more IPM oriented, and wit more and better postemergence options, growers might be more inclined to move in that direction and use economic thresholds in their management decisio s. This is unlikely. In both corn and soybeans, there already are options for postemergence control of most weeds but very few growers have used economi thresholds in their management decisions. Most fields are suffici ntly infested that the question is not whether an application is needed ut rather what to treat with. In the small percentage of fields where populat ons are marginal enough to make one question the need for treatment, the var ability in those low weed populations is so great that the intensity of scou ing necessary to accurately use thresholds seldom can be economically justifi d. In c ntrast to corn and soybean, HTC's could encourage changes in cotton product'on systems. In addition to expanding the area of production, as discuss d above, HTC's likely will lead to more no-till cotton. Although cotton creage planted no-till is increasing, fear of weed control failures continu s to scare some growers away from no-till cotton.
153 The impact by growers, a HTC's compare ultimately wi program using and various f performance 0 Over time, re locally adapt nematode and will be a pro f HTC's will obviously depend upon how well they are accepted d that in turn will depend upon the economics of systems using with standard systems. At this point, it is unclear how that 1 settle out. A grower must consider the cost of an overall HTC's compared with standard systems. Increased cost of seed es for use of the technology must be included. The agronomic HTC's relative to standard cultivars must also be considered. istance to particular herbicides will be moved into a number of , high yielding cultivars with various desirable traits such as isease resistance. In the short term, agronomic performance lem in some situations.
