Barley, Chickpeas, Faba Beans, Field Peas, Lentils, Lupins, Wheat: Apply by ground rig only in a minimum of 50 L water/ha. Water rate selection should be based on soil type and stubble load. Stubble loads above 40 to 50% ground coverage can reduce weed control below acceptable levels. Water volumes greater than 70 L/ha are recommended in order to reduce the impact of stubble in direct drill or minimum tillage systems. Potatoes: Apply by ground rig only in a minimum of 100 L water/ha.
