Selective and Non-Selective Herbicides. Selective herbicides kill one type of plant but not another–for example, grass weeds but not broad-leaved weeds. This selectivity may be due to differences in herbicide absorption, translocation or physiological differences between weeds and the turfgrass. Nonselective herbicides
Nonselective, Contact herbicide. Rapid (within hours). Effective on seedling annuals. Top kill only on perennials and larger established annuals. Odor can persist for days. Eye & skin irritant. Scythe (pelargonic acid). Page 5. Scythe. Contact burn. Fast – within 30 min on a sunny day. Page 6. Nonselective, Postemergent.
SPRAY DRIFT RESTRAINTS. DO NOT apply with spray droplets smaller than a MEDIUM spray droplet size category according to nozzle manufacturers specifications that refer to the ASABE S572 Standard or the BCPC Guideline. DO NOT apply when wind speed is less than 3 or more than 20 km per hour as measured at
Herbicides are the chemicals which are employed to kill or control vegetation. Common salt, ash, smelter waste etc. have been used for centuries to control weeds, but selective control of weeds in agriculture was first conceived in 1896 in France, when Bordeaux mixture sprayed on grapevines for protecting it from downy
Selective Herbicide. A herbicide for control of woody plants, annuals and perennial broadleaf weeds in forests, grass pastures, rangeland, and CRP acres including non-irrigation ditch banks and fence rows within these areas. ACTIVE INGREDIENT: *Triclopyr BEE: (3,5,6 Trichloro-2-Pyridinyl) oxyacetic acid, butoxyethyl
plants. Extreme care should be taken to avoid spray contact on the foliage of desired vegetation. • Preemergence and/or pre-plant applied herbicides for residual control of weeds in selected ornamental plants. • Postemergence selective weed control in specific ornamental plants. • Products applied for burndown of existing
Herbicide activity can be either selective or non-selective. Selective herbicides are used to kill weeds without significant damage to desirable plants. Nonselective herbicides kill or injure all plants present if applied at an adequate rate. Herbicides provide a convenient, economical, and effective way to control weeds.
Selective Herbicide. Dispersible granules for both preemergence and postemergence control of many annual and perennial grasses and broadleaf weeds; conifer and hardwood site preparation and release; general weed control in noncrop industrial sites; and can be tank mixed with other herbicides for use in forestry and
25 Aug 2009 Burr Ridge, IL 60527. SUBJECT: Application for Pesticide Notification (PRN 98-10). Request Primary Brand Name "Patriot Selective Herbicide". EPA Reg. No. 228-391.

gence herbicides are applied as weeds will emerge in these areas. Length of control with preemergence herbicides de- creases with increases in rainfall, irrigation, organic matter content and clay content. Preemergence herbicide may be. “selective" or “nonselective" with respect to types of plants controlled. EXAMPLES:
