The parasite may or may not penetrate the mycelium of the fungus it is parasitizing. This statement is ________.

The parasitic fungus secretes enzymes that digest the mycelium walls of the pathogenic fungus. This statement is ________.

The mechanism by which a fungal parasite attacks the pathogenic fungal structures includes wrapping around the mycelium. This statement is ________.

Biological control involves the use of chemical agents to combat pathogens. This statement is ________.

The parasitic fungus can penetrate the hyphae of the host fungus and grow inside these hyphae, as happens to the fungus R. solani with many algal fungi and the fungus Didymella exitialis. This process is known as _____________.

In some cases, hyphae of the parasitic fungus can wrap around the mycelium of the host fungus and secrete enzymes to digest it. This process is known as ____________.

The success rate of biological control of the disease decreases if the environmental conditions are suitable for the pathogen and not suitable for the parasite. True or False?

The use of fungal parasites in biological control is limited due to the high costs of preparing the inoculate and adding it to the field soil. True or False?

Lack of practical knowledge about using fungal parasites in biological control is one of the reasons for its limited use. True or False?
