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
Diseases caused by P. syringae tend to be favoured by wet, cool conditions—optimum temperatures for disease tend to be around 12–25 °C (54–77 °F), although this can vary according to the pathovar involved. The bacteria tend to be seed-borne, and are dispersed between plants by rain splash. [18]
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. [14] [15]
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.
Each bacterial chromosome entry in BacMap now contains graphs and tables on a variety of gene and protein statistics. All of the bacterial species listed in BacMap now have bacterial 'biography' cards, with corresponding information on the microbe’s taxonomy, phenotypic traits , other descriptions and electron microscopy or other high ...
Halo blight of bean is a bacterial disease caused by Pseudomonas syringae pv. phaseolicola. Halo blight’s pathogen is a gram-negative, aerobic, polar-flagellated and non-spore forming bacteria. This bacterial disease was first discovered in the early 1920s, and rapidly became the major disease of beans throughout the world.
