The latest edition continues the tradition set by the original book, and covers weed science research that has been published since 1980. This book aims to reduce the instance of research duplication-saving scientists and supporting institutions time and money. Not only does the second edition of Weed Crop Competition review, summarize, and combine current research; it critiques the research as well. This text has the potential to accelerate advancements in weed crop c 606 $aWeeds 606 $aPlant competition 606 $aWeeds$vBibliography 606 $aPlant competition$vBibliography 615 0$aWeeds. 615 0$aPlant competition. 615 0$aWeeds 615 0$aPlant competition 676 $a632.5 700 $aZimdahl$b Robert L$0282942 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910877033503321 996 $aWeed-crop competition$92132522 997 $aUNINA
