COMPARATIVE EVALUATION OF DIFFERENT APPLICATION RATES AND TIMES OF FURADAN (CARBOFURAN) 3% G IN SUGARCANE CROP FOR MANAGING BORERS ATTACK AND YIELD ENHANCEMENT

The experimental study was conducted to assess furadan 3% g (carbofuran) borers control level, impact on yield and the level of residue in sugarcane tops and juice . the experiments were conducted in 2 consecutive years 2011-12 & 2012-13 at research farm of sugarcane research institute, faisalabad. five dosages in split applications (32, 40, 48, 48 and 32 kg/acre) were evaluated with different application timings. sugarcane setts of t5 were sprayed with bifenthrin 10% ec before sowing. in 1^st year minimum damage by top borer (2.04%), stem borer (1.17%) and root borer (1.82%) was recorded by t3 (48kg/acre) along with minimum cumulative inter-node damage (5.04%) was found statically significant to all other treatments and the yield was also highest in t3 i.e. 103.88 t ha^-1. in 2^nd year experiment showing the same trend and the minimum damage by top borer (2.05%), stem borer (2.52%) and root borer (1.08%) found in t3 (48kg) which is statistically significant than the other treatments and the highest yield (108.39 t ha^-1) was also recorded in t3. the residues in cane tops and juice were below the detectable limits.
