ABSTRACT
Eurasian watermilfoil has become a most troublesome aquatic weed. Due to its rapid growth rate, fragmentation, migration, and establishment, milfoil is a serious and real threat to our water resources. Eurasian watermilfoil is a perennial having a wide range of environmental tolerances. The historic pattern of watermilfoil growth, like that of most exotics, seems to be an explosive development following introduction, a stabilized growth at a relatively high incidence, and ultimately a gradual subsidence to a lower level in equilibrium with native vegetation. Eurasian watermilfoil can withstand considerable wave action and daily tidal fluctuation of several feet, but grows best in sheltered coves. It is found in numerous areas of Yugoslavia and in many different habitats. Plant overpopulation disables fish production, limits the use of irrigation and drainage canals, disrupts recreation boating activities, and in some areas interferes with hydroelectric power production. The primary purpose of milfoil control is to alleviate social and economic problems associated with watermilfoil infestation.
