Compositions are provided that improve overall plant vigor and yield by combining agriculturally effective amounts of at least one environmentally friendly biological control agent and at least one insect control agent and or fungicide. A composition of the present invention is particularly effective in the presence of plant parasitic nematode and fungal species. Along with a benefit of reducing insect pressure, the inventive composition enhances the root system of a plant and improves the establishment of the biological control agent within the rhizosphere, thereby enhancing the effectiveness thereof. Use of a composition of the present invention leads to an overall reduction in crop losses caused by either plant parasitic nematodes or fungi and this reduction is much greater than would have been expected from application of either component alone. Methods for utilizing compositions of the present invention are also provided. Further the compositions according to this invention display synergistic insecticidal, nematicidal, acaricidal or fungicidal activity.藉由組合農業上有效量的至少一種環保有益生物控制劑和至少一種昆蟲防治劑及/或殺真菌劑提供可改善整體植物活力和產量的組成物。本發明組成物特別有效用於存在植物寄生性線蟲和真菌品種。本發明組成物除了具有降低昆蟲壓力的效益之外可強化植物的根部系統以及改善根際內生物控制劑的建立，因而加強其有效性。使用本發明的組成物可降低植物寄生線蟲或真菌導致的整體作物損失以及該降低遠大於單獨撒佈各別成分所預期的效應。亦提供運用本發明組成物的方法。根據本發明的組成物更展示出殺蟲、殺線蟲、殺蟎或殺真菌的協同活性。
