Therefore, successful farming relies on their control by coordinated management approaches. Among these, chemical herbicides are of key importance. Their development and commercialization began in the 1940's and they allowed for a qualitative increase in crop yield and quality when it was most needed. This book blends review chapters with scientific studies, creating an overview of some the current trends in the field of herbicides. Included are environmental studies on their toxicity and impact on natural populations, methods to reduce herbicide inputs and therefore overall non-target toxicity, and the use of bioherbicides as natural alternatives. 517 $aHerbicides 606 $aHerbicides 606 $aHerbicides$xEnvironmental aspects 610 $aPest control 615 0$aHerbicides. 615 0$aHerbicides$xEnvironmental aspects. 676 $a632.954 700 $aAlvarez-Fernandez$b Ruben$4edt$01366705 702 $aAlvarez-Fernandez$b Ruben 801 0$bNjHacI 801 1$bNjHacl 906 $aBOOK 912 $a9910138411103321 996 $aHerbicides$93389300 997 $aUNINA
