SOMERESEARCHANDWEEDCONTROL METHODS WITHASPARAGUS l , , ;,! W. H. Lachman lif·'r .' " .: 215 , \ The study of ~eed problems in asparagus beds is quite var~ed in nat~~e and scope since many different weeds invade all aspaiagus plantations. These may vary from gras~es to broad-leafed sort. and from annuals, ~~ennial~ to perennial types. Oft-en quack gra.s (Agropyron repens) is the 'invader along with other insidious pests such as milkweed (Asclepias. syriaca), horsetail: (Equhetum arvense) and bindweed (Con:\rolvulvus arven8i6) not to mention young asparagus seedlings self-sown by the crop ltself. ...' Weed control in asparagus 18 a problem which h.s been 8tudl.~d at ~~e, Massachusetts Statton for many years (4,5).
