Therefore, it is important to guarantee a successful soybean crop every growing season. Bacterial blight can be found in most soybean fields every year in the Midwest. [2] Yield losses due to Pseudomonas syringae pv. glycinea have been reported as anywhere from 4% to 40% depending on the severity of the conditions. [1]
Bacterial diseases; Bacterial blight Pseudomonas amygdali pv. glycinea: Bacterial pustules Xanthomonas axonopodis pv. glycines = Xanthomonas campestris pv. glycines: Bacterial tan spot Curtobacterium flaccumfaciens pv. flaccumfaciens = Corynebacterium flaccumfaciens pv. flaccumfaciens: Bacterial wilt Curtobacterium flaccumfaciens pv. flaccumfaciens
Compared to 23 common soybean diseases, sclerotinia stem rot was the second most problematic disease in the United States from 1996 to 2009. [ 8 ] [ 9 ] For soybeans, crop yields are inversely correlated with the incidence of Sclerotinia stem rot; an estimated of 0.25 metric ton per ha is lost for each 10% increment of diseased plants.
The impact factor relates to a specific time period; it is possible to calculate it for any desired period. For example, the JCR also includes a five-year impact factor, which is calculated by dividing the number of citations to the journal in a given year by the number of articles published in that journal in the previous five years.

Pseudomonas syringae is a rod-shaped, Gram-negative bacterium with polar flagella.As a plant pathogen, it can infect a wide range of species, and exists as over 50 different pathovars, [2] all of which are available to researchers from international culture collections such as the NCPPB, ICMP, and others.
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
The primary bacterial diseases include bacterial blight, bacterial pustule and downy mildew affecting the soybean plant. [ 34 ] The Japanese beetle ( Popillia japonica ) poses a significant threat to agricultural crops, including soybeans, due to its voracious feeding habits.
While these journals still did not receive an impact factor until the next year, they did contribute citations to the calculation of other journals' impact factors. [ 4 ] [ 5 ] In July 2022, Clarivate announced that journals in the ESCI obtain an impact factor effective from JCR Year 2022 first released in June 2023.
