MANAGEMENT STUDIES ON ROOT ROT OF <em>PROSOPIS</em> <em>CINERARIA</em> CAUSED BY <em>FUSARIUM</em> <em>SOLANI</em>

Abstract

Screening of seven systemic and non-systemic fungicides in in vitro studies revealed the superiority of all  the fungicides in controlling mycelial growth of Fusarium solani which causes root rot of Prosopis cinerana, though their efficacy varied Topsin-M showed 11% inhibition at 50 ppm whereas Emisan and Bavistin did so at 100 ppm concentration Bavistin and Topsin-M also retained their supremacy in seed treatment and pre sowing drenching Soil amendments with crop residues or oil cakes indicated  mustard cake amendment as most effecuve followed by cotton cake and saw dust Biological antagonist Trichoderma viride controlled the disease to 50% under in vivo condition
