International Journal of Current Microbiology and Applied Sciences(2018)
Abstract
The investigation was carried out at Horticulture research farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during Rabi-summer, 2014-15 and 2015-16. The mean data revealed that among the treatments, during first season DIFACE 600 ml/ha (Difenthiuron50% WP + Acetamiprid 20% SP) recorded the mean of lowest population 3.29 and 3.35 thrips/3 leaves per plant as against 9.33 and 9.43 thrips in untreated check, respectively after first and second spray. During second season (Rabi-summer 2015-16) after 1st and 2nd spray almost similar trends were observed and minimum mean population of thrips (1.57 and 1.97) were recorded in DIFACE 600 ml/ha treatment. In both seasons, field experiment revealed that among the various treatment Fenpropathrin 30% EC @ 340 ml/ha recorded maximum mean coccinellid and spider population.
