Apply from May to October (June to August for woody weeds) when soil is moist and weeds are actively growing. For tree stumps, the best time for treatment is Autumn or Winter, avoiding April, May or June when the sap is rising. This 1Ltr pack treats up to 340 square metres. Always read the label on your purchased product before use. Use pesticides safely.
