Plant Disease Research

Foliar spray of two chemical compounds viz., calcium chloride and ß-amino-n-butyric acid @ 25mM was found to induce resistance in rice plants artificially inoculated with D. oryzae grown under stress conditions of nitrogen and water. Calcium chloride was superior over ß - amino-n-butyric acid in reducing disease severity under both nitrogen and water stress conditions. The interaction between the chemical compound and N-level; chemical compound and irrigation condition was non significant indicating that both the stress conditions did not affect the efficacy of these chemical compounds in induction of resistance.
