Abstract

Numerous application techniques have been described for glyphosate herbicide ranging from the conventional knapsack sprayer CKS to aerial application for weed control. In Malaysia glyphosate herbicide has been applied in spray volumes ranging from 100 to 1100 litres per hectare using conventional knapsack sprayer and from 20 to 50 litres per hectare using control droplet applicators CDA from control of Imperata cylindrica L. Beauv and general weed control respectively. The flexibility of glyphosate herbicide to numerous applications systems and techniques is due to its completely water soluble formulation its translocated mode of action and other favourable features. In 1988 Monsanto Malaysia evaluated an ultra low volume technique for applying glyphosate based herbicides for general weed control. Trial results and experiences from several rubber and oil palm plantations have shown a high level of consistency in efficacy and efficiency of glyphosate based herbicides when applied through this ultra low volume technique. Called the SOLO ULV technique this equipment delivers spray volumes from 10 to 50 litres/ha and can improve the efficacy and efficiency of glyphosate based herbicides significantly. The equipment and technique also reduces labour requirement by half and water requirement by 90 percent. It is easy to operate and reliable with regular maintenance. A large data base exists to show acceptable levels of exposure of glyphosate when applied through the mistblower. Notwithstanding the fact it is always good practice and common sense to wear suitable and practical protective clothing whenever applying pesticides.
