Farmers participatory on farm evaluation of IPM technology and chemical pesticides against major pests of Brinjal

SS Singh and Sanjay Sachan

The present field experiment was carried out during the summer seasons of 2013 and 2014, respectively (March to August each year) with F1 brinjal hybrid, Chhaya in farmers participatory on farm evaluation of IPM technology and chemical pesticides against major pests of brinjal at three locations of Dehradun (Uttarakhand). The results of the investigation revealed that treatment 1 received lowest incidence of mean shoot damage, mean fruit damage of shoot and fruit borer, red spider mite and bacterial wilt. The infestation of mean shoot damage varied from 2.06 to 36.20 during 2013 and 3.21 to 39.73 during 2014. Similarly mean fruit damage ranges from 5.26 to 44.35 and 4.08 to 47.26 during 2013 and 2014, respectively. Incidence of red spider mite was also recorded which varied from 4.15 to 74.59 per cent in 2013 and 2.87 to 78.26 per cent in 2014. The incidence of bacterial wilt was also found which ranges from 1.02 to 31.66 and 0.80 to 37.28 per cent during 2013 and 2014, respectively. The incidence of bacterial wilt was managed successfully in treatment 1 due to introduction of bacterial wilt tolerant hybrid i.e. Chhaya. The experimentations also envisaged that treatment 1 fetched maximum mean fruit yield i.e. 556.24 Q/ha in 2013 and 544.80 Q/ha in 2014 which was significantly superior over all other treatments during both years.
