ABSTRACT:
Fungal pathogen is applied to weeds in such a manner that misting or an extended dew period is not necessary to germinate and grow the fungus. In particular, an oil-in-water invert emulsion containing a special additive is applied to the weeds at the same time or immediately after application of the fungal pathogen, wherein the special additive is (a) wax or (b) lecithin in combination with a calcium salt. Lecithin particularly is effective as an emulsifying agent for forming the emulsion, and for forming invert emulsions for applying chemical herbicides to weeds.
