Ahmad Faiz M. A., . Effects of herbicide mixtures surfactants and spray volumes on the control of Imperata cylindrica (L.) raeuschel. pp. 179-189. ISSN 1511-1768

The effects of selected herbicide fixtures surfactants and spray volumes on Imperata cylindrica under immature rubber were compared. Mixtures of glyphosate at 1.08 kg ae/ha with either 2 4-D dimethylamine at 0.03 0.05 or 0.08kg ae/ha or fluroxypyr at 0.01 0.02 or 0.03 kg ae/ha resulted in reduced control. Mixtures of glyphosate at 1.08 kg ae/ha with glufosinate ammonium at 0.15 or 0.3 kg ai/ha produced comparable control while reduced control was obtained when mixed with paraquat at 0.2 or 0.4kg ai/ha. Glyphosate at 0.54 kg ae/ha improved control when mixed with imazapyr at 0.3 kg ae/ha while comparable control was obtained when glyphosate at 1.08 kg ae/ha was mixed with imazapyr at 0.15 or 0.3 kg ae/ha. Glyphosate at 1.08 or 2.16 kg ae/ha exhibited slight enhancement in control when mixed with the cationic surfactants Hyspray 52 Ethokem or Arsenal 62. Addition of the organosilicone surfactant Pulse 250 at 1.0 or 2.0 l/ha to glyphosate at 1.08 kg ae/ha or imazapyr at 0.5kg ae/ha improved control Spray volumes of 85 l/ha with the controlled droplet applicator or 480 560 and 640 l/ha with the knapsack sprayer using glyphosate at 1.44 kg ae./ha or imazapyr at 0.5 kg ae/ha showed almost comparable control.

Abstract

The effects of selected herbicide fixtures surfactants and spray volumes on Imperata cylindrica under immature rubber were compared. Mixtures of glyphosate at 1.08 kg ae/ha with either 2 4-D dimethylamine at 0.03 0.05 or 0.08kg ae/ha or fluroxypyr at 0.01 0.02 or 0.03 kg ae/ha resulted in reduced control. Mixtures of glyphosate at 1.08 kg ae/ha with glufosinate ammonium at 0.15 or 0.3 kg ai/ha produced comparable control while reduced control was obtained when mixed with paraquat at 0.2 or 0.4kg ai/ha. Glyphosate at 0.54 kg ae/ha improved control when mixed with imazapyr at 0.3 kg ae/ha while comparable control was obtained when glyphosate at 1.08 kg ae/ha was mixed with imazapyr at 0.15 or 0.3 kg ae/ha. Glyphosate at 1.08 or 2.16 kg ae/ha exhibited slight enhancement in control when mixed with the cationic surfactants Hyspray 52 Ethokem or Arsenal 62. Addition of the organosilicone surfactant Pulse 250 at 1.0 or 2.0 l/ha to glyphosate at 1.08 kg ae/ha or imazapyr at 0.5kg ae/ha improved control Spray volumes of 85 l/ha with the controlled droplet applicator or 480 560 and 640 l/ha with the knapsack sprayer using glyphosate at 1.44 kg ae./ha or imazapyr at 0.5 kg ae/ha showed almost comparable control.
