Field Efficacy and Phytotoxicity Evaluation of Metiram 70 WG Against Tikka Disease in Groundnut

摘要

A field experiment was conducted during Kharif-2017 comprising six treatments which replicated four times under farmer's field. During the current study an attempt was made to evaluate different doses of Metiram 70 WG for effective management of Tikka leaf spot disease of Groundnut. The results from field experiment showed that, spraying of Metiram 70 WG @ 2500 g/ha was found effective in registering the lowest leaf spot severity of 14.81 Percent Diseases Index (PDI) which was on par with Metiram 70 WG @ 2000 g/ha of both market sample (15.03 PDI) and test sample (16.47 PDI). Data pertaining to percent disease control over untreated check was observed higher in Metiram 70 WG @ 2500 g/ha (78.32 ). The highest pod yield was documented in plots applied with Metiram 70 WG @ 2500 g/ha (3016.06 kg/ha) followed with Metiram 70 WG @ 2000 g/ha of both market sample (2934.82 kg/ha) and test sample (2957.75kg/ ha). In perusal of information generated in the present investigation it is envisaged that, spraying of Metiram 70 WG @ 2500 or Metiram 70 WG @ 2000 g/ha were found to be effective dose of fungicides in the management of the disease under field condition as well as successfully suppressed the secondary spread after resorting curative measures.
