SIA-BRA: A database of animal stable carbon and nitrogen isotope ratios of Brazil. Repository: BDPA Publication year: 2022
Liquid culture production of microsclerotia and submerged conidia by Trichoderma harzianum active against damping-off disease caused by Rhizoctonia solani. Media and culturing protocols were identified that supported the formation of submerged conidia and microsclerotia (MS) by Trichoderma harzianum Rifai strain T-22 using liquid culture fermentation. Li... ... Repository: BDPA Publication year: 2015
