Biological control of peach twig blight (Monilinia laxa) with Penicillium frequentans
In 1986 and 1988 various preparations of spores and or mycelium of the antagonist Penicillium frequentans, alone or in alternation with captan were applied to field‐grown peach trees inoculated with Monilinia laxa, the cause of twig blight. Some preparations of P. frequentans containing nutrients gave significant reductions in severity of disease (from 38 to 80%) over control, comparable to that given by captan. Combinations of P. frequentans and captan gave a level of control similar to or less than that given by the antagonist or chemical alone. Populations ofP. frequentans on shoots were monitored after application in 1986. When applied with nutrients, levels of P. frequentans on shoots remained higher than when the fungus was applied in the absence of nutrients. In a glasshouse experiment the effect of P. frequentans treatments on twig blight was influenced by the type and amount of M. laxa inoculum applied. Copyright © 1990, Wiley Blackwell.
