               3.2.2 Restriction fragment length polymorphisms
               RFLP of DNA of chosen genes can be utilized to distinguish path-
               ogen species. This way to deal with species distinguishing proof
               depends on having a brilliant database on the inconstancy in
               piece-length polymorphisms that might be found among segre-
               gates of individual species, since conspecific segregates may
               contrast in the nearness or nonattendance of specific limitation
               destinations, thus changing the RFLP banding profile [12].

               3.2.3 Amplified fragment length polymorphism
               AFLP is an alteration of the RFLP system, which has been utilized
               for species identification and to look at genotypic assorted variety
               within population. The last quality helps to observe the realistic
               cause of pathogens related to new infection flare-ups, as for the
               situation. Although the AFLP examination is an incredible diag-
               nostic tool, it is difficult in representing, actually requesting,
               and not appropriate for routine use in symptomatic facilities [13].


               4. Innovative detection method

               Nourishment misfortunes because of yield contaminations from
               pathogens, for example, microscopic organisms, infections, and
               growths, are constant issues in horticulture for a considerable
               length of time over the globe. To limit the disease-actuated
               harm in crops during development, collect, and postharvest
               handling, just as to expand profitability and guarantee farming
               supportability, propelled malady recognition and avoidance in
               crops are basic. There are some immediate and backhanded
               sickness distinguishing proof strategies as of now utilized in horti-
               culture. There are numbers of lab-based techniques that are as
               follows: PCR, immunofluorescence (IF), fluorescence in situ
               hybridization (FISH), ELISA, flow cytometry (FCM), and gas
               chromatographyemass spectrometry (GC-MS), which are some
               of the direct detection methods. Indirect methods include ther-
               mography, fluorescence imaging, and hyperspectral techniques.
                  Although the decline in horticultural efficiency can be credited
               to an assortment of reasons, harm brought about by irritations
               and pathogens assumes a critical job in crop misfortunes all
               through the world. The misfortunes in crop yield because of
               pathogen contaminations extend somewhere in the range of
               20% and 40% [14]. All things considered, pathogen-incited misfor-
               tunes of maize, grain, rice, and soybean are evaluated to be
               around 12%, groundnuts and potatoes are assessed to be around
