For control of certain weeds in clover-based Pasture, Field Peas, Lentils, Lupins and Oilseed Poppy.

GENERAL INSTRUCTIONS
For use as an early post-emergence spray in clover-based pasture, field peas, lentils and lupins. Conquest Defcon 500 SC Selective Herbicide may also be used as a pre-emergence spray on lupins in NSW, ACT, Vic, SA and Tas.
This product provides both contact and residual activity. Residual activity can be expected for up to 8 weeks after application under favourable growing conditions.
This product is taken up by the shoots of germinating seeds and seedlings. Susceptible weeds germinate but show immediate chlorosis followed by a mauve-pink discolouration. The chlorosis spreads with the aerial growth and the plants become necrotic and die back.
After application, some transient crop discolouration may occur. In lentils and lupins, this usually appears as yellow or white banding on the leaves, while in clover and field peas, white/pink colouration of the leaf veins and tips may occur. Some crop height reduction may also occur.
Provided the crop is not under stress from pre-emergent herbicide, disease, insect damage, nutrient deficiency, frost, extremes of pH, dry or excessively moist conditions, the development of the crop and all subsequent growth will not be affected.
Some pre-emergence herbicides, such as atrazine, can cause stress to certain crops resulting in an increase in crop damage when using this product. Field peas are particularly sensitive.

Mixing
Stir product or invert container several times before use as settling may occur after storage for some weeks. To ensure even mixing, half fill the spray tank with clean water and add the required amount of product. Agitate thoroughly then add the remainder of the water. Agitate thoroughly while carrying out spray operations. Reseal part-used container immediately after use.

Application
Ground: A minimum water rate of 50L/ha should be used, however, for optimum results water rates of 70- 100L/ha are recommended. Increase the water volume where weed infestation is heavy or the crop cover is dense. Complete coverage of weeds is essential. Higher water volumes (up to 100L/ha) will ensure improved activity of the product on the weeds but may increase the symptoms of crop damage.
