 ITEM 1.  SECURITY AND ISSUER.

          The title of the class of equity  securities  to which this  statement
          relates is common  stock,  $.01 par value  (the  "Common  Stock"),  of
          Senesco  Technologies,  Inc., a Delaware  corporation (the "Company").
          The address of the  principal  executive  offices of the Company is 34
          Chambers Street, Princeton, New Jersey 08542.

 ITEM 2.  IDENTITY AND BACKGROUND.

          This   Statement  on  Schedule  13D  is  being  filed  by  Phillip  O.
          Escaravage,  the sole member of The Umbrella  Project,  L.L.C.,  a New
          Jersey  limited  liability  company   ("Umbrella").   The  address  of
          Umbrella's  principal place of business and principal office is 95 Old
          Dutch Road, Far Hills, NJ 07931.  Umbrella's  principal  business is a
          holding  company  which  invests  in a variety  of  business  entities
          conducting various  activities.  Mr. Escaravage is a citizen of Canada
          but a resident alien of the United States.

          During the last five years,  neither  Umbrella nor Mr.  Escaravage has
          been convicted in a criminal proceeding  (excluding traffic violations
          or similar  misdemeanors),  and Umbrella or Mr.  Escaravage  was not a
          party to a civil  proceeding of a judicial or  administrative  body of
          competent  jurisdiction  as a result of which  proceeding it was or is
          subject  to  a  judgment,  decree  or  final  order  enjoining  future
          violations  of, or  prohibiting  or mandating  activities  subject to,
          federal or state securities laws or finding any violation with respect
          to such laws.

 ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

          On  October  9,  1998,   Senesco,   Inc.,  a  New  Jersey  corporation
          ("Senesco"),  Nava Leisure USA, Inc., an Idaho  corporation  ("Nava"),
          Nava  Leisure   Acquisition   Corp.,  a  New  Jersey  corporation  and
          wholly-owned   subsidiary   of  Nava   ("NAC"),   and  the   Principal
          Stockholders (as defined therein),  entered into an Agreement and Plan
          of Merger,  providing for the merger of NAC with and into Senesco, and
          the issuance to the  shareholders of Senesco one newly issued share of
          Common Stock of Nava for each share of Common Stock of Senesco whereby
          the  shareholders  of Senesco  acquired  a majority  of the issued and
          outstanding shares of Common Stock of Nava (the "Merger").  The Merger
          was  consummated  on  January  22,  1999,  the  date  upon  which  the
          Certificate  of Merger filed with the  Secretary of State of the State
          of New Jersey was declared  effective.  Upon the  consummation  of the
          Merger,   Senesco  was  the  surviving   corporation  and  remained  a
          subsidiary  of Nava which  changed  its name to Senesco  Technologies,
          Inc., an Idaho corporation ("STI").

          Umbrella was a shareholder of Senesco and  beneficially  owned 933,476
          shares of Common  Stock of  Senesco.  As a result  of the  Merger,  on
          January 22, 1999,  Umbrella received 933,476 shares of Common Stock of
          STI (formerly  Nava),  consisting of 34.57% of the 2,700,008 shares of
          STI Common Stock issued and outstanding.

          On  September  7,  1999,  STI  granted  to Mr.  Escaravage  options to
          purchase  40,000  shares of STI Common  Stock,  on a post stock  split
          adjusted  basis (as described  below),  at an exercise  price equal to
          $3.85 per share. Mr. Escaravage received such options as consideration
          for his services as a Director of STI. All such options are  currently
          vested.

          On September 29, 1999, STI declared a two-for-one  forward stock split
          of  its  issued  and  outstanding  Common  Stock  and,  as  a  result,
          Umbrella's holdings of STI Common Stock increased to 1,866,952 shares,
          excluding any options to purchase shares of STI Common Stock.


                                   Page 3 of 6


          On September 30, 1999,  STI merged with and into the Company,  for the
          sole  purpose of  reincorporating  the  corporation  from the State of
          Idaho to the State of Delaware.

          Pursuant  to a Common  Stock  Purchase  Agreement  by and  between the
          Company and Umbrella, dated as of January 31, 2000, Umbrella purchased
          34,737  shares  of  the  Company's  restricted  Common  Stock  for  an
          aggregate  purchase  price  of  $100,000,   using  Umbrella's  working
          capital.

 ITEM 4.  PURPOSE OF TRANSACTION.

          Mr. Escaravage is the founder of Senesco and a current director of the
          Company.  The acquisition of the shares of the Company's  Common Stock
          reported  herein were made to acquire a voting interest in the Company
          and an equity investment interest in the Company.  Umbrella and/or Mr.
          Escaravage may from time to time,  depending  upon market  conditions,
          the  state of  affairs  of the  Company  and  other  factors,  acquire
          additional  shares  of  Common  Stock  of  the  Company,   subject  to
          applicable  laws and to the  availability  of shares at prices  deemed
          favorable.  Alternatively,  Umbrella and/or Mr. Escaravage may dispose
          of  shares  of  the  Company's  Common  Stock.   Umbrella  and/or  Mr.
          Escaravage will continue to consider their respective equity interests
          in the Company and they reserve the right to  formulate  such plans or
          proposals,  and to take such action,  as may seem appropriate in light
          of future circumstances.

          Except as set forth above,  neither  Umbrella nor Mr.  Escaravage have
          any present plans or intentions which would result in or relate to any
          of the following:

          (a)  The  acquisition  by any person of  additional  securities of the
               Company, or the disposition of securities of the Company;

          (b)  An  extraordinary  corporate  transaction,   such  as  a  merger,
               reorganization or liquidation, involving the Company;

          (c)  A sale or transfer of a material amount of assets of the Company;

          (d)  Any change in the present board of directors or management of the
               Company, including any plans or proposals to change the number or
               terms of  directors  or to fill  any  existing  vacancies  on the
               board;

          (e)  Any  material  change in the present  capitalization  or dividend
               policy of the Company;

          (f)  Any other material change in the Company's  business or corporate
               structure;

          (g)  Changes  in  the  Company's   charter,   bylaws  or   instruments
               corresponding  thereto  or other  actions  which may  impede  the
               acquisition of control of the Company by any person;

          (h)  Causing a class of  securities of the Company to be delisted from
               a national securities exchange or to cease to be authorized to be
               quoted  in  an  inter-dealer  quotation  system  of a  registered
               national securities association;

          (i)  A class of equity securities of the Company becoming eligible for
               termination of registration  pursuant to Section  12(g)(4) of the
               Act; or

          (j)  Any action similar to any of those enumerated above.

 ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

          (a)  Umbrella  is  the  record  holder  of  1,840,465  shares  of  the
               Company's  Common  Stock.  As the sole  member of  Umbrella,  Mr.
               Escaravage is the beneficial owner of the 1,840,465 shares of the
               Company's  common stock held of record by Umbrella.  In addition,
               Mr.  Escaravage is the direct and beneficial  owner of options to
               purchase 40,000 shares of the Company's  Common Stock,  which are
               currently  exercisable.  In


                                   Page 4 of 6


               the  aggregate,   Mr.  Escaravage  is  the  beneficial  owner  of
               1,880,465 shares of the Company's common stock,  including 40,000
               options  to  purchase  the  Company's   common  stock  which  are
               exercisable within 60 days,  representing 23.8% of the issued and
               outstanding  shares  of the  Company's  common  stock,  based  on
               7,872,626 issued and outstanding shares reported on the Company's
               proxy statement filed with the Securities and Exchange Commission
               on October 27, 2000.

          (b)  Mr.  Escaravage  has the sole power to vote and the sole power to
               dispose of 1,840,465  shares of the  Company's  Common Stock held
               solely by  Umbrella.  Mr.  Escaravage  also has the sole power to
               vote and the sole  power to dispose  of and  options to  purchase
               40,000 shares of the Company's Common Stock held solely by him.

          (c)  On  September  7, 1999,  the  Company  granted to Mr.  Escaravage
               options to purchase 40,000 shares of the Company's  Common Stock,
               at an exercise  price  equal to $3.85 per share,  with 50% of the
               options  vesting  on the  date of  grant  and 50% of the  options
               vesting  on June  30,  2000.  Such  options  were  issued  to Mr.
               Escaravage in consideration for his services as a director of the
               Company.

               Pursuant to a Common Stock Purchase  Agreement by and between the
               Company and Umbrella, dated as of January 18, 2000, Umbrella sold
               61,224 shares of the Company's Common Stock to an unrelated third
               party for an aggregate purchase price of $150,000.

               Pursuant to a Common Stock Purchase  Agreement by and between the
               Company  and  Umbrella,  dated as of January 31,  2000,  Umbrella
               purchased  34,737  shares of the  Company's  Common  Stock for an
               aggregate purchase price of $100,000.

               The percentage of the issued and outstanding  Common Stock of the
               Company beneficially owned by Umbrella was materially reduced due
               to (i) the sale by Umbrella of 61,224  shares of Common  Stock to
               an  unrelated  third  party,  and  (ii)  the  Company's   private
               placement of 1,471,700  shares of its  restricted  Common  Stock,
               completed in June, 2000.

          (d)  No other  person  is known to have the  right to  receive  or the
               power to direct the receipt of  dividends  from,  or the proceeds
               from the sale of, such securities.

          (e)  Not applicable.

 ITEM 6.  CONTRACTS,  ARRANGEMENTS,  UNDERSTANDINGS OR  RELATIONSHIPS  WITH  THE
          ISSUER.

          There  is no  contract,  arrangement,  understanding  or  relationship
          (legal or otherwise)  between Umbrella and the Company with respect to
          any securities of the Company,  including but not limited to, transfer
          of voting of any of the  securities,  finder's fees,  joint  ventures,
          loan or option  arrangements,  puts or calls,  guarantees  of profits,
          division of profits or loss, or the giving or withholding of proxies.
