CROP GENETICS ANNOUNCES ENCOURAGING RESULTS OF 1991 CORN FIELD TRIALS; InCide REDUCED DAMAGE TO CORN BY 26 PERCENT TO 72 PERCENT

CROP GENETICS ANNOUNCES ENCOURAGING RESULTS OF 1991 CORN FIELD TRIALS;
 InCide REDUCED DAMAGE TO CORN BY 26 PERCENT TO 72 PERCENT
 HANOVER, Md., Nov. 14 /PRNewswire/ -- Crop Genetics International (NASDAQ: CROP) reported today that in Nebraska field trials its InCide(TM) corn borer bioinsecticide demonstrated significant insect control in 12 corn hybrids.
 Under insect infestation levels considered "moderate" by Nebraska standards, Crop's unique technology reduced the amount of damage caused by the corn borer from 26 percent to 72 percent depending upon the corn hybrid. The hybrids tested came from a select range of germplasm that is the source for many of the Midwest and Central Plains commercial corn varieties. Crop said that it studied the agronomic characteristics of each corn hybrid inoculated with its InCide bioinsecticide and is correlating the observed effects with the inbred parents of the hybrids in order to predict which other corn varieties may be compatible with its InCide system.
 Crop's InCide corn borer bioinsecticide consists of a naturally occurring microorganism which can exist in the vascular system of corn plants like a vaccine. Crop's scientists have genetically engineered the microorganism to produce a biotoxin which is harmless to humans and animals but fatal to corn borers that feed on plants inoculated with the InCide vaccine. The corn borer causes about $500 million damage each year to American corn Crop. Crop's InCide bioinsecticide system is designed to provide consistent, season-long protection from the insect, thereby increasing U.S. grain yields and eliminating the need for external application for insecticides.
 Dr. Mark Beach, director of bioinsecticides at Crop, said he and his scientific colleagues were pleased with the Nebraska field results not only because of the demonstrated bioinsecticide activity but also because they are now better able to predict the compatibility of corn varieties with Crop's InCide technology. Beach further explained, "In determining the compatibility of the InCide system with particular corn hybrids, we compared a range of agronomic characteristics, including germination rates, growth parameters, bioinsecticide activity, and yield in both the presence and absence of corn borer infestations with the known pedigree of that hybrid."
 "We have now completed four years of field testing of our genetically engineered bioinsecticide with the approval of the Environmental Protection Agency and the United States Department of Agriculture," reported Dr. James Davis, vice president of research and development of Crop. In the first two years of testing, Crop focused on the safety aspects of its InCide system. He said Crop tested a working prototype of its InCide corn borer vaccine in Maryland in 1990 and again in Nebraska this year, with similar results. "With the genetic improvements in the vaccine that are currently underway in our laboratories" continued Davis, "we hope to test an enhanced version of the bioinsecticide in 1992, especially in those hybrids we have determined may be most compatible with the InCide system."
 Four other hybrids tested by Crop in Nebraska showed reductions in insect damage of 10 percent to 20 percent but the reductions were not statistically significant at the 95 percent confidence level. Crop also conducted field trials in Maryland, but the level of corn borer infestation was generally too low for measurement of insect control.
 Crop Genetics International is developing biological pesticide systems to control insects, diseases and weeds in agriculture and forestry. The company's research is focused on the creation of novel Crop protection products that are effective and compatible with the environment. The company's INSTAR(TM) division is developing manufacturing processes for viral insecticides; its x-tend(TM) group is focused on developing weed control systems that combine biological and synthetic herbicidal agents; its InCide technology is designed to use genetically engineered plant inoculants to protect corn, rice and other major row Crops from insects and fungi; and its Kleentek(R) business markets disease-free sugarcane seed.
