Ụlọ nkwakọba ihe maka ọgwụ

Trichodermin nwere spores na mycelium nke ero Trichoderma lignorum, yana ihe ndị na-arụ ọrụ n'ụzọ dị ndụ nke ero na-emepụta.

Trichoderma bụ fungi saprophytic nwere uto mycelial ngwa ngwa yana ike ime mgbanwe na gburugburu ebe obibi. Ha nwere ike ọnyà ụfọdụ fungi pathogenic na mgbọrọgwụ nke osisi ahụ, si otú a na-egbochi mbuso agha nke fungi na-emerụ ahụ (pathogens). Saprotrophs nwekwara ike itinye ngwa ngwa nri dị mkpa maka uto nke fungi pathogenic, nke na-eduga na ụkọ ha, na-egbochi mmepe na mmepụta nke pathogens.

Usoro nke ime ihe

Ọnụ ọgụgụ nke Trichoderma dị elu karịa nke fungi pathogenic, ya mere, ọ nwere ike igbochi mmepe nke fungi pathogenic. Trichoderma hymenoptera mgbe fatịlaịza n'ime ala maka awa 24 na-echebe ngwa ngwa nke mgbọrọgwụ nke ihe ọkụkụ, na-eke ihe mgbochi nchebe megide mbuso agha nke pathogens.

Ọtụtụ nchọpụta egosila na ọtụtụ Trichoderma spp nwere ike ịmepụta ogige bioactive ma nwee mmetụta mgbochi na fungi phytopathogenic fungi na nematodes. Ihe ndị a na-arụ ọrụ ndụ, nke na-ebibi mgbidi cell, nwere ike ịbawanye nkwụsi ike nke ihe ọkụkụ nke ọma, belata ọrịa nke osisi ma kwalite mmepe ha.
