169 Potential ~pact of Herbicide-Resistant Crops on Specialty and Minor Crops Leonard P. Gianessi 1 This papet'coversthe potentialimpactsof geneticallyengineeredherbicideresistant cultivarsfor min9r crops.The paperfocusesprimarilyon vegetablessincegeneticallyalteringtree and vine crops tojtolerateherbicidesis not likely to gain muchattention. The paper also discusses impactson min01crops of the developmentof herbicideresistantfieldcrops such as soybeans. The minot crop problemis fairlywell known. Thereis an absenceof herbicidesfor most vegetablecrops. lOver70%of vegetablecrops lackeither preemergenceor postemergence herbicidesthat provide effectivebroadspectrumweedcontrol. As a result,vegetablegrowers are forced to use expensive handlabor or plastic to controlweeds. What's the potentialof biotechnologytojprovidemore optionsfor minor crop vegetablegrowers? I Why aren't there moreherbicidesfor minor cropsright now? It's due to the high cost of registrationand ~e potentialrisk of damagingcropsthat are worththousandsof dollars an acre. The costs are high, the risksare high and the marketis small. Herbicidemanufacturershavelittle interestin marketingherbicidesfor minorcrops even if farmershavea demonstratedneed. Will bioengineeredplants offer a way out of thisproblem? National!erbiCidesalesdata demonstratethe disparityin herbicidemarkets. Soybean growers spend $ .5 billion a year on herbicides. Con. growersspendaboutthe same. Com, soybeansand co onjustify the millionsof dollarsrequiredto developa new herbicideand gain registration. Th~ nationalmarketfor potatoherbicidesis $32 million. Thus, an herbicidethat would be a goodlfit for potatoesis unlikelyto be developedunlessit also has com, soybeanor cotton use. All dther vegetablestotal$91 millionin herbicidesales. That's about 30 different crops. These ardvery smallmarkets. Some ha~e said that the U.S. doesn't really need anothersoybeanherbicide. There are 26 herbicideactiveingredientscurrentlyused in soybeans. There is not a lot of handweedingor use of plastic in soybeans. Meanwhile,carrots,lettuceand peppershave three to six herbicides registeredand itiuse. Soybeangrowershave numerouspre and post-emergenceherbicide options. For jUs~ about any weedinfestingsoybeans.there are numerousoptionsfor control. However, U.S. ~rowers are going to have anothermajor herbicideaddedto the soybeanweed control arsenal./ Monsantohas developedglyphosateresistantsoybeans. Throughbiotechnology,soybean plants have beeriengineeredto resistglyphosate. Soybeanplantswithoutthe resistancegene are killed by glyphcrate applications. By plantingthe resistantsoybeanplants,growerswill be able to go over the toprsoybean plantswith glyphosatefor_weedcontrol. One of thereasonswhy soybeangrowersare likelyto adoptthe use of glyphosateis potentialreduction of herbicidecosts. Currently,soybeangrowersaroundthe country spend $22 to $32 an acre fpr their herbicides. The use of glyphosatecouldpotentiallyreducethis cost to $8 i 1 Senior Research ~sociate, National Center for Food and Agricultural Policy, 1616 P Street, NW, Washington, DC 20036. !
