Abstract:
Series laboratory and greenhouse experiments were conducted to investigate the effects of
bacteria, Potassium Phosphate Dihydrate and citric acid on early developmental stages of Striga
hermonthica and explore their potential for deployment as a component of an integrated
management strategy. In vitro experiments, results revealed that germination of S.
hermonthicasignificantly decreased after inoculation with bacterial cultures alone or in
combination with Potassium Phosphate Dihydrate and citric acid. Striga seeds treated with
KH2PO4 alone or in combination with ISO10, BMP, Flavobacterium or Flavobacterium +BMP
reduced germination by 50-83% as compared to the corresponding control. Moreover, the
application of KH2PO4 (30 and 50µM) alone or in combination with Iso10 andISO10 and
BMP+Flavobacteriumsignificantly (P?0.5) increased shoot and root dry weights compared to the
corresponding control. With-respect to Striga dry weight result showed that all treatment reduced
Striga dry weight. In among treatments, KH2PO4(30 and 50µM) and bacterial isolateISO10 each
alone and their combinations gave the best results in reducing Striga dry weight. |
