Experiment Title Studies on variability of Alternaria leaf spot/ Corynespora leaf spot disease
Research Type AICRP on Cotton
Experiment Background  The naturally infected leaves showing the symptoms of Alternaria leaf spot/ Corynespora leaf spot diseases will be collected from the Research farm and as well as from the farmer’s field.  The samples will be collected and brought to the laboratory and these leave samples will be thoroughly washed with the tap water.  Morphological characters of Alternaria leaf spot/ Corynespora leaf spot disease will be studied by observing slides under a microscope.  Isolation and culturing will also be done as per standard methodology.  Sending isolates to PI (ICAR-CICR, SIRSA) for further identification and registration. Alternaria/ Corynespora isolated from the leaf blight samples with confirmed pathogencity for diverse analysis at species level will be send to Cotton Pathologist at Department of Cotton, Tamil Nadu Agricultural University, Coimbatore 641 003.

Objective

To study the variability of cotton pathogens

For Corynespora leaf spot disease, we have studied the following aspects:

  1. To study the different temperature on morphology and cultural characteristics of pathogen
  2. To evaluate the efficacy of different bioagents under in vitro condition
  3. To evaluate the efficacy of different fungicides under in vitro condition
  4.       Evaluation of different growth media on Corynespora cassiicola under in vitro test
  5.      In vitro evaluation of different plant extracts on the growth of Corynespora cassiicola
  6. In vitro evaluation of different pH on the growth of Corynespora cassiicola
