SPATIO-TEMPORAL ANALYSIS OF CUCUMBER MOSAIC VIRUS DISEASE AND ITS SUSTAINABLE MANAGEMENT

Cucumber fields were surveyed in the vicinity of Sargodha to map the spatial and temporal CMV disease distribution. Infected samples were collected for pathogenicity tests, biophysical properties and serological assays. After confirmation of virus; data of disease prevalence, incidence and severity was recorded which showed strong positive linear relationship. There was gradual increase in disease after each temporal assessment. Bhatti Town (BT) showed more than 90% disease prevalence followed by College of Agriculture (COA) and Adaptive Research Farm (ARF). This experiment also demonstrated the significant contribution of NPK solution, Naphthalene acetic acid (NAA), benzothiadiazole (BTH) and elephant ear plant (EEP) extract in improving the cucumber performance against CMV disease. There was positive linear relationship between all disease parameters. All the treatments gave significant contribution for sustainable disease management. NPK was the efficient among rest of the treatments with more than 75% disease inhibition. The second most effective treatment was BTH followed by NAA and EEP with 63%, 55% and 39% disease control, respectively. The study provided useful information for estimation disease dynamics in varied spatio-temporal scales. It could be concluded that NPK and BTH are the suitable tools for sustainable management of CMV disease.
