Title

APPLICATION OF SYSTEMIC FUNGICIDES VIA RICE ROOT AND INVESTIGATION ON THEIR EFFECTIVENESS AND DURABILITY FOR CONTROL OF RICE BLAST DISEASE

Pages

  47-56

Abstract

 The effectiveness and durability of four SYSTEMIC FUNGICIDES, BENOMYL (BEN), FTHALIDE (FTH), PYROQUILON (PYR) and TRICYCLAZOLE (TRIC) for control of RICE BLAST DISEASE was investigated by in vivo and in planta tests. Fungicides used once for rice root treatment as suspension in irrigation water. In greenhouse, treated rice plants were exposed to disease infection, in blast nursery, at different times and disease incidence was evaluated one week later. In field experiments, treated rice plots were compared for leaf blast. panicle blast, and yield with control (untreated) plots. The results indicated that HEN, PYR and TRIC could be taken up and systemically translocated in rice plants and be effective to control blast disease of foliage. In greenhouse, HEN could control disease up to 50% at I day after treatment (DAT) and to 100% at 2 DAT but in spite of rapid uptake and efficacy, had shorter lasting efficacy so that controlled disease up to 14 DAT and then reduced its efficacy. PYR and TRIC could control disease at 4 DAT but had long lasting efficacy and controlled disease up to 28 DAT. In comparison, only partial disease control could be obtained by FTH during 4-21 DAT. In the field, PYR and TRIC significantly controlled leaf blast but in the cases of panicle blast and yield were not significantly different with control. Once application of BEN could not provide considerable control of disease, probably because of its shorter lasting efficacy, and was not significantly differel1twith FTH and control.
