ABSTRACT
Series of operations to determine the amount of solution applied per uni t area of land and the amount of chemical required for a known volume of diluent. A meristem wi th products of divisions arranged in an orderly fashion in parallel files. It consists of one layer of init ial cells and their derivatives. The l iquid or solid added to a chemical compound to facilitate its application. The type of antagonism that occurs when an an tagonist reacts chemically w i t h a herbicide to form an inactive complex. The loss of green colour (yellowing) in plant foli age resulting from the impairment or stoppage of the green colouring matter. The nature of two compounds that permits them to be mixed wi thout affecting the properties of ei ther. The type of antagonism that occurs when an an tagonist acts reversibly at the same site as the her bicide. The active acquisition of limited resources by an organism that results in a reduced supply and con sequently reduced growth of other organisms in an environment. The amount of active ingredient in a given volume of diluent or given weight of dry material. The herbicide that kills pr imar i ly by contact wi th plant tissue rather than as a result of translocation. The process of l imi t ing an infestation. The tissue region between the epidermis and vas cular system of a plant. The first leaf or pair of leaves (depending on wheth er the p lant is monocoty ledonous or d icoty ledonous) of the embryo of seed plants. (Also re ferred as Cotyledon Leaves). In the context of weeds, it is an expression of mech anism that confers plants the ability to resist or withstand herbicides from different classes. The point where stem and root join in a seed plant. The jointed stem of a grass which is usually hol low except at the nodes or joints. A thin, continuous, non-cellular, l ipoidal membrane (varnish-like layer) covering the entire plant sur face (shoot), formed by oxidation of plant oils. The chief structural component of cuticle, composed of polymerized long-chain fatty acids and alcohols, protecting the photosynthetic mechanisms of plant cell. The plants which lose their leaves dur ing the win ter.
