Abstract
  • The perennial weed is an insidious enemy that like a bad habit seems harmless until so entrenched that casting out is difficult. The first few patches seem lacking in ambition and content with their lot. They grow for years more or less unnoticed. Then all at once covered. When they reach this stage of almost complete possession of a field, control is expensive and may be beyond the means of the owner. As a result, on several thousand acres in Oregon, crop produc­tion has been abandoned and the weeds and the mortgage are the only growing things on the farm. Yet control is easy and costs little if undertaken when the first small patch appears. It is the purpose of this bulletin to discuss control measures and to suggest battle formations for community wars on weeds. Those who do not recognize their enemies on sight, and wish to be able to do so, may find pictures and descriptions of some of the worst of the perennials in separate leaflets, listed on page 71. Although annual weeds do plenty af damage, no attempt is made here to discuss them. This bulletin is limited to perennial weeds.
