Identification of weeds resistant to paraeforce(r)‎ and aminoforce(r)‎ herbicides

Abstract EN

Field experiment was conducted in the dry season between December 2012 to April 2013 at Bakori, Bakori local government, Katsina (11033'N, 7036'E).

The experiment consisted of 8 treatments which include 4 different formulations each; viz: ParaeForce(R)(Paraquat) at 150mL / 20L and 200ml / 20L and AminoForce(R) at 100ml / 15L and 125ml / 15L applied a day before sowing and 4 weeks after sowing and a weedy control.

A randomized complete block design was used to lay out the treatments (RCBD).

Ten families with total amount of seventeen species were documented including Ipomoea vagans, Doctylocterium aegyptium, Cyperus rotundus, Cynodon dactylon, and Eleusine indica.

Exhibited significant (0.05) resistance to ParaeForce(R) + AminoForce(R) at 150mL / 20L, followed by 100mL / 15L, with 29, 31, 17.17, and 7.67 weed count at 4, 8 and 16 WAS, respectively, representing 91.70, 87.12, and 49.15 % weed control efficiencies.

Sequential application of ParaeForce(R) + AminoForce(R) at 200mL/20L followed by 125mL/15L recorded significantly (≥0.05) low weed count with 13.33, 40 and 6.0 at 4, 8 and 16WAS which represent 86.28, 77.58 and 33.55% weed control efficiencies.

This study recommended application of ParaeForce(R) and AminoForce(R) at 200mL/20L followed by 125mL/15L as alternative way of reducing weed resistance to ParaeForce(R) + AminoForce(R) Field experiment was conducted in the dry season between December 2012 to April 2013 at Bakori, Bakori local government, Katsina (11033'N, 7036'E).
