Abstract: Methods and compositions for increasing the availability of soluble phosphate and fixed nitrogen for legume:Rhizobium symbioses involving co-inoculating legume seeds with a phosphate-solubilizing soil fungus, Penicillium bilaii, and Rhizobium spp. prior to planting. The two types of microorganisms do not appear to compete for nutrients in the rhizosphere of legumes and the P. bilaii provides a source of available phosphorus for use by the plant without adversely affecting the nitrogen fixation ability of the Rhizobium spp.; and indeed such ability is enhanced. The invention is used to increase the efficiencies of nodulation, nitrogen fixation and legume crop production.

Abstract: Commercial mycoherbicide compositions for the control of round-leaved mallow weeds (Malva pusilla Sm.), the active ingredient being the spores of the fungus Colletotrichum gloeosporioides f.sp. malvae, ATCC 20767, these spores having been produced by a two-phase multi-staged liquid fermentation process, then separated from the mycelial biomass and concentrated into a spore slurry. The active ingredient of the mycoherbicide compositions, i.e., spores, can be packaged as a concentrated spore slurry or alternatively, dried and then packaged. Both the liquid and dry forms of the myco-herbicide are packaged in gas- and water-impermeable containers. The spores are stabilized prior to packaging or drying by the addition of a stabilizing agent or alternatively, stabilized after drying by adjusting their final water content. The initial, i.e.
