Provided herein is a microbial pesticide formulation composition that, by containing acetic acid, improves the activity of the biopesticidal filamentous fungus contained as an active pesticide component having a disease and/or pest and/or weed control effect, and, a plant growth regulating effect while being preservable for long periods of time. A method for producing such compositions, and a method for controlling pests and weeds, and a method for regulating plant growth with the use of the composition are also provided, among others. This is achieved with use of a pesticide formulation composition that includes: a biopesticidal filamentous fungus solid culture using a solid medium which is at least one selected from a grain seed, and a hull, bran, and a polished product of a grain seed； and acetic acid.本發明係提供一種具有對於病害蟲及/或雜草之防除作用，以及植物之成長調整作用之農藥活性成分之生物農藥絲狀菌，在藉由乙酸經高活性化之微生物農藥製劑組成物，可長期保存之微生物農藥製劑組成物、其製造方法及藉由該使用之病害蟲或雜草之防除方法、植物成長調整方法等。本發明的解決手段為藉由使用含有將選自穀物之種子、其外皮、麩、精白物中之1種以上作為固體培養基之生物農藥絲狀菌固體培養物、與乙酸而成之農藥製劑組成物，解決上述課題。
