Information @ a Glance

Contents on the CD Rom

• Acephate is an organophosphate foliar spray insecticide of moderate persistence with residual systemic activity of about 10-15 days at the
  recommended use rate.
• Acephate and its primary metabolite, methamidophos, are toxic to Heliothis spp that are considered resistant to other organophosphate insecticides.
• Acephate is an important systemic organophosphorus insecticide with toxicity attributed to bioactivation on metabolic conversion to
  methamidophos  which acts as an acetylcholinesterase inhibitor.
• Acephate is quickly absorbed, translocated, and transformed in pine seedlings and cotton plants.
• The chemical was metabolized via cleavage of the amide bond to form methamidophos and an unknown, but insecticidally active compound, which were identified in the roots, stems, and leaves.
• Methamidophos was also found in cotton leaves following a single application of acephate.
• Acephate is rapidly absorbed into the leaf tissue of cotton plants when applied foliarly, with nearly 40% of the applied acephate present in the
  internal extract and 25% remaining on the leaf surface 24 hours after application.
• The un recovered acephate probably was trans located from the leaves or bound in un extractable form in the leaf tissue.
• Acephate should be used at the bud and pin stages on processing beans. Once pins are present on fresh market snap beans and trap catches are
  above 2 per night, a 7-10 day schedule should be maintained for corn borer control.
• It is used for control of a wide range of biting and sucking insects, especially aphids, including resistant species, in fruit, vegetables  vine, and hop cultivation and in horticulture.
• It controls parasites of cattle, goats, hogs, horses, poultry, and sheep, where tolerances have been set for milk, eggs, fat, and meat.
• Acephate is used for household use or golf course spray.
