Evaluation of Some Insecticidal Combinations and Neem (Azadirachta indica A. Juss) Extracts Against Jassids and Whitefly on Cotton and Their Effect on the Yield
Masood Khan Ktattak, Liaqatullah Khan, Mohammad Naeem Awan and Agha Shah Hussain

Abstract: The insecticidal combinations and the neem extracts at their recommended doses reduced 70.2-95.3% pest infestation 2days after the spray but gradually decreased to 6.5-39.6% infestation 17 days after the spray. Baythroid-TM 525EC ranked first in the initial as well as in its residual toxicity to the test insect pests, followed by Polytrin-C, Decis-D, and neem extracts (Ethanol, Hexane, Chloroform, and Water). Water extract of neem was inferior to other treatments in its toxicity and its effect on the yield of cotton. The highest yield 1915 Kg/hectare was obtained from the plots treated with Baythroid-TM.
