Application of plant growth promoting Rhizobacteria in combination with Biopesticides in controlling major insect pests of cauliflower

Abstract

The present investigation was conducted to know the effect of PGPR and biopesticides viz., T1 (Absolute control), T2 (Application of chemical pesticides), T3 (Inoculation of PGPR), T4 (Application of Trichoderma), T5 (Inoculation of PGPR + Neem cake), T6 (Application of Trichoderma +Neem cake), T7 (Inoculation of PGPR +Trichoderma + Neem cake). The experiment comprised of 7 different treatment combinations and four replication. Results from the study indicated that combined Inoculation of PGPR +Trichoderma + Neem cake along with seedling treatment gave significantly higher plant height (25.83cm), number of clean leaves (18.75/plant), incidence of aphids in leaves (0.25), survival percentage (94.66%),shoot dry weight (9.03g), root dry weight(3.47g), head weight (473.43g). Therefore, it may be concluded that combined Inoculation of PGPR +Trichoderma + Neem cake along with seedling treatment was the most effective treatment combination for higher growth and yield in Cauliflower.
