In view of the ecological hazards of chemicals, pot experiments were conducted to determine the efficacy of Trichoderma sp. against Macrophomina phaseolina. Greenhouse evolution of the interaction between M. phaseolina isolates and Trichoderma sp. (isolated revealed a very highly significant (p=0.0000). M. phaseolina isolate x antagonist isolate interaction for all the following parameters: preemergence damping-off, postemergence damping-off, survival, plant height, and dry weight. This interaction implies that a single isolate of antagonist can be highly effective against an isolate of M. phaseolina, but may have only minimal effects on other isolates of M. phaseolina. Therefore, isolates of antagonist should be tested against as many isolates of M. phaseolina as possible, as this will improve the chance of identifying antagonist isolates effective against several isolates of M. phaseolina.

PL

Doświadczenia szklarniowe nad współdziałaniem pomiędzy izolatami M. phasedina i izolatami Trichoderma sp. wykazały bardzo wysoką istotność (p = 0,0000) współdziałania izolatu M. phaseolina z isolatem grzyba antagonistycznego dla wszystkich następujących parametrów: zgorzel przedwschodowa, zgorzel powschodowa, przeżywalność, wysokość roślin i sucha masa. To współdziałanie sugeruje, że pojedynczy izolat grzyba antagonistycznego może być wysoce efektywny wobec izolatu M. phaseolina, ale może on mieć tylko minimalny efekt w stosunku do innych izolatów M. phaseolina. Właściwości izolatów antagonistycznych powinny więc być przebadane przy wykorzystaniu możliwie dużej liczby izolatów M. phaseolina, ponieważ to rozszerzy możliwość zidentyfikowania ich efektywności wobec pewnej liczby izolatów tego patogena.
