Abstract:
A field experiment was conducted at Agricultural college and Research Institute, Madurai during, 2019-20 to evaluate the bio-efficacy of herbicide mixtures on weed and productivity of cotton. Statistical design used in the experiment is Split plot and replicated thrice. Treatments tested were, three weed detection techniques as main plot and the different herbicide mixtures were allotted to sub plots. The herbicide mixtures were quantified and applied based on the weed spread area. Comparing all the herbicide mixtures, the experimental investigation concludes that application of 75% dosage of Quizalofop ethyl @ 50 g a.i ha-1 + Pyrithiobac Sodium @ 62.5 g a.i ha-1 at 15 DAS as early post emergence herbicide followed by Post emergence application of Fluazifop at 140 g a.i ha-1 + Fenoxoprop at 40 g a.i. ha-1 at 40 DAS, saved the quantity of herbicide, also exhibits higher bio efficacy with the detection of weeds through drone camera (M3).
