Pesticides may not only change the genetic structure of a plant population, but also cause damage, sterility, and malformed outgrowths (morphoses) of the autonomic and reproductive organs. For example, up to 70% of barley plants treated with pesticides were observed to have ear malformation. Using 2,4-D and foxim on barley increased the number of plants with morphoses by a factor of 18-24 [3].

The accurate analysis of genetic variation in nematodes has major implications for parasite identification and for investigating population genetic structures (Lejambre, 1993 Grant, 1994). Conventional DNA methods have been valuable and their application has provided a wealth of molecular data (reviewed by McManus and Bowles, 1996), but little attention has been paid to their capacity to resolve sequence variation (reviewed by Gasser, 1997). For instance, PCR-RFLP analysis using (multiple) restriction endonucleases is useful, but sequence variation may go undetected as...
