An emulsifiable concentrate containing 320 g/L prochloraz, 40 g/L proquinazid and 160 g/L tebuconazole for disease control in wheat, barley and oats, rye and triticale.
CROPS AND TIMING
VAREON can be used on all winter and spring varieties of wheat, barley and oats, rye and triticale.
Best results are obtained when applied before disease is established in the crop. A further application may be made after 3 weeks. Applications to crops where symptoms are present are likely to be less effective.
RATE AND APPLICATION
Apply VAREON at 1.25 l/ha. Apply in 150-300 l water/ha using a MEDIUM spray quality (as defined by BCPC). Low volumes are not advised in dense crops at later growth stages.
DISEASE RESISTANCE
When fungicides with the same mode of action are used repeatedly over several years in the same field, naturally occurring less sensitive strains may survive, propagate and become dominant in that field. A pathogen is considered resistant to a fungicide if it survives a correctly applied treatment at the recommended dose and timing, under normal weather conditions. Development of resistance within a pathogen can be avoided or delayed by alternating or mixing products having a different mode of action. The Fungicide Resistance Action Group has produced guidelines on the management and avoidance of fungicide resistance. Details of these can be obtained from your supplier or DuPont.
Resistance to DMI fungicides has been identified in Septoria leaf blotch (Mycosphaerella graminicola), which may seriously affect the performance of some products. For further advice on resistance management, contact your agronomist or specialist advisor.
MIXING
Ensure sprayer is clean before use. VAREON containers should be shaken well before use.
VAREON mixes easily with water and should be added directly to the spray tank during filling. Half fill the spray tank with clean water. Add the required quantity of VAREON, add the remained of water and begin agitation. Wash out container and add washings to the spray tank. Continue agitation during filling and when spraying.
