Abstract
Sudden and unpredictable heavy rain showers are common in the wet tropical climate of Malaysia. Application of herbicides in Malaysia are at risk to washout by rain. Based on rainfall data collected over the last 15 years it is estimated that freshly applied herbicides are subjected to a 50 per cent daily chance of washout by rain. Herbicide washouts result in economic losses for plantations in terms of loss of labour chemicals and bioefficacy. Several herbicides including paraquat glufosinate-ammonium glyphosate and sulfosate were evaluated for rainfast properties. Results revealed that paraquat was found to be rainfast in 15 minutes i.e. it will not be rainwashed even if rain falls at 15 minutes after spray. Glufosinate-ammonium and glyphosate were not rainfast and poor weed control was recorded even when rain fell at 6 hours after spray. In a separate experiment sulfosate was found to be more rainfast than glyphosate.
