The availability of biological agents in the abundant natural would be a huge potential . This needs to be kept in mind and disseminated to farmers , extension workers , and other agricultural stakeholders . Biological agents that we will discuss today is the fungus Trichoderma . Potential
antagonistic fungus Trichoderma as a preventative against fungal plant
diseases has made the more widely used by farmers in an effort to
control plant pests ( OPT ) . Besides its character as an antagonist also known that Trichoderma sp . Also function as decomposers in the manufacture of organic fertilizer . Trichoderma applications in plant breeding in order to anticipate the
pest attack as early as possible to prove that the level of farmers'
awareness of the importance of preventive protection has grown slowly .
Trichoderma sp are often used to control Fusariumoxysporum ( cause stem rot disease on vanilla plant ) , Phytophtora sp ( disease-causing stem rot on pepper plants ) and Rigidoporus lignosus ( white root disease-causing fungus on rubber plant ) . It also effectively control Phytium sp which is a soil -borne pathogens causing damping-off disease on beans .
This fungus has several advantages , among others :
1 . Easily isolated , developed , and wide adaptability
2 . Easily found in soil planting area , allows for growth at the moment the application easier .
3 . Can grow rapidly on a variety of substrates .
4 . Having a wide range mikroparasitisme .
5 . generally not patoen in plants .
Trichoderma fungi have the ability to increase the speed of plant growth and development , particularly its ability to cause the production of healthy roots and increase the depth of the roots ( deeper below ground level ) . The deeper root causes plants to become more resistant to drought , such as the corn crop and ornamental plants .
The mechanism of this antagonistic fungus can be understood as follows . When pathogenic microbes are in a period of dormancy , antagonistic fungus Trichoderma attack can cause damage to biological pathogen inoculum . This antagonistic mechanism may be predation , perparasi , and parasitism propagules . Another form of antagonism is the suppression of germination propagules through the competition of carbon , nitrogen , iron ions , oxygen and other important elements . While on the surface tanman antagonists include antibiosis , competition and predation .
Mikoparasitisme of Trichoderma Sp . is a complex process consisting of several stages in the attacking host. Initial interaction of Trichoderma Sp . that is by hifanya veering towards fungal host is attacked , this phenomenon indicates kemotropik response to Trichoderma Sp . due to the stimulation of the host hyfa or chemical compounds released by the host fungus . When it reaches its host mikoparasit , hifanya then twist or squeeze the host hyphae by forming structures such as hooks ( hook - like structure ) , this mikoparasit Juka sometimes penetrates the host mycelium partially degrade the host cell wall .
Mechanism of action of Trichoderma spp . ( one of which is T. koningii ) is a way of suppressing the development of JAP with antibiotics and mikroparasitisme formation , competition and colonization rizomorfa . The mechanism of destruction Roots Mushroom White ( JAP ) occurs through the process of lysis of mycelium and rizomorfa . Lysis is an enzymatic process by cellulose enzymes produced by T. koningii .
Trichoderma harzianum suppress the growth of fungi on plants kentang.Jamur phythoptora infestan trichoderma fungal isolates harsianum is local , so if using compost will support the breeding of this trichoderma fungi that can suppress the growth of Phythopthora dilahan potatoes .
Trichoderma is one type of fungus mikroparasitik / fungus is parasitic on the type sifat2 lain.Nah because of this that trichoderma can be utilized as a biocontrol agent against fungal jenis2 fitopatogen . Advantages and keunggulanya is easily monitored and can breed , so its presence in the environment to survive .
