The field experiment was conducted at Student’s Instructional Farm, Acharya Narendra Dev University of Agriculture & Technology, Kumarganj, Ayodhya during Rabi, 2017-18. Reduction in larval population recorded at 7 days after second spraying revealed that all the treatments were effective and significantly superior to control. The treatments viz., Rynaxypyr 20 SC @ 18 g a.i./ha, 2% Urea + Rynaxypyr 20 SC @ 18 g a.i./ha, Emamectin benzoate 5 SG @ 11 g a.i./ha, Flubendiamide 480 SC @ 60 g a.i./ha and 2% Urea + Flubendiamide 480 SC @ 60 g a.i./ha gave 100 per cent reduction in larval population followed by 2% Urea + Emamectin benzoate 5 SG @ 11 g a.i./ha that gave 88.23 per cent reduction in larval population. The highest benefit of ` 38400/ha was recorded by Rynaxypyr 20 SC @ 18 g a.i./ha followed by 2% Urea + Rynaxypyr 20 SC @ 18 g a.i./ha (` 37920/ha). The next best treatments were Flubendiamide 480 SC @ 60 g a.i./ha and 2% Urea + Flubendiamide 480 SC @ 60 g a.i./ha with financial benefit of ` 32100/ha and ` 22800/ha, respectively. Similarly, Emamectin benzoate 5 SG @ 11 g a.i./ha and 2% Urea + Emamectin benzoate 5 SG @ 11 g a.i./ha recorded financial benefit of ` 18000/ha and ` 13800/ha, respectively. It is interesting to note that insecticides alone recorded higher financial benefits as compared to their combination with 2% urea, due to increased cost. Thus, addition of 2% urea with insecticides is not a good option. [ABSTRACT FROM AUTHOR] |
