EFFECT OF HERBICIDAL APPLICATION ON INCIDENCE OF INSECT PESTS AND NATURAL ENEMIES
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 5
Abstract
The incidence / population of various insect pests and natural enemies were recorded at weekly interval on rice cultivar CSR 30 under transplanted condition with different herbicidal treatments during Kharif 2013 and 2014. The overall seasonal population of plant hoppers varied from 185.5 to 197.8 and 15.42 to 16.70 plant hoppers/10hills during 2013 and 2014, respectively. All the treatments were on par with each other. The seasonal mean incidence of stem borers varied from 3.93 to 4.82 and 4.67 to 5.49 per cent in different treatments during 2013 and 2014, respectively. There was no significant difference in the incidence of stem borer in different treatments during both the years. The incidence of rice leaf folder fluctuated during both the seasons with overall mean incidence of 5.98 to 6.51 per cent in 2013 and 3.87 to 4.17 per cent damaged leaves in 2014 and none of the herbicide neither increase nor decrease leaf folder incidence. There was no significant difference in the spiders population in different herbicidal treatments during 2013 and 2014. The average grain yield in different treatments was statistically at par with each other during both the years.
