In an advanced stage of development there are for example: Bacillus subtilis for seed treatment and control of Sphaerotheca fuliginea on zucchini squash; Trichoderma spp. for soilborne pathogens; and Gliocladium roseum for the control of Botrytis cinerea in greenhouse cultivated strawberry.  abiological control  aBrazil  aCutacuttmu forrendiellu  aMicrocyclw tllei  aPreimmunization  aTristeza virus  tWorld Journal of Microbiology & Biotechnologygv.12, nº 5, p.505-510, 1996
