COMPOSITIONS FOR TREATING CITRUS DISEASE AND PROMOTING YIELD INCREASE IN ROW CROPS

Isolated bioactive priming peptides and bioactive priming compostions comprising bioactive priming polypeptides and/or inducer compounds are provided that are useful when applied to plants in agricultural formulations. Methods of using the isolated bioactive priming peptides and/or compositions are also provided which are applied exogenously to the surface of a plant or a plant cell membrane or endogenously to the interior of a plant or to a plant cell. The isolated bioactive priming peptides and/or bioactive priming compositions when applied to a plant， a plant part， or a plant growth medium or a rhizosphere in an area surrounding the plant or the plant part increase growth， yield， health， longevity， productivity， and/or vigor of a plant or a plant part and/or protect the plant or the plant part from disease， and/or increase the innate immune response of the plant or the plant part and/or improve the quality and/or quantity of juice obtained from a plant or plant part.
