The invention is also directed to an environmentally friendly broad spectrum systemic plant function regulator composition having a mixture of extracts of plants and which substantially lacks glyphosate on a weight basis. The herbicide composition can be in effective on plants having 5-enolpyruvyl shikimic acid-3- phos phate synthase from Agrobacterium . The invention is also directed to a process of making the herbicide and plant function regulator compositions and to methods of using them. w o 2011/083363 A : llll II II 11III II I III III II II II III II I II (84) Designated States (unless otherwise indicated, for every SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, kind of regional protection available): ARIPO (BW, GH, GW, ML, MR, NE, SN, TD, TG).

FIELD [0002] The application is generally directed to plant herbicides and plant extracts that regulate plant growth. More particularly, the application discloses- an herbicide composition suitable for use in conventional or organic agriculture, or other uses in an environmentally friendly manner, methods of using the herbicide composition, and methods of making the herbicide composition. BACKGROUND [0003] Broad spectrum herbicides are widely used in agriculture to inhibit the growth or spread of unwanted competing plants, termed weeds, to prepare fields for seeding, and to favor transgenic plants having resistance genes. Herbicides can be used before the weeds emerge (pre-emergence) or after the weeds germinate (post-emergence). Herbicides are further classified as systemic or contact herbicides. Contact herbicides act primarily on the part of the plant to which the herbicide is applied. Systemic herbicides are transported within the plant vascular system(s) and affect most or all the plant, including the root. In general, contact herbicides have a more rapid effect than systemic herbicides, but are generally less effective in killing perennial plants. [0004] Moreover, synthetic herbicides cannot be used in organic agriculture. Major agricultural nations have regulations governing materials suitable for use in agriculture. In the USA, the Department of Agriculture provides the National List of Allowed and Prohibited Substances for organic agriculture and other countries have regulations for similar purposes. [0005] Prominent synthetic herbicides include systemic compounds such as glyphosate (ROUNDUP®), which dominates the market, atrazine, sulfonylureas such as chlorsulfuron, aryloxyphenoxypropanoates such as diclofop, and contact herbicides including glufosinate, paraquat, and diquat. The widespread use of these herbicides has led to serious problems, including evolution of resistant weeds, drift of herbicide spray into unwanted areas onto desirable plants, and contamination of ground water. Toxic effects in mammals have led to a program for phase-out of paraquat in Europe and restriction on use in Japan. [0006] Natural products have been used in agriculture.
