DIRECTIONS FOR USE
Mixing
To ensure even distribution of contents immediately before measuring, gently invert the container a few times. Half fill the spray tank with clean water and add the measured quantity of ROVER 500 whilst agitation is in progress. Complete filling of the water and continue agitation throughout the spraying application.
 
Spray Quality
Apply as a medium spray as defined by BCPC.
 
Cleaning
On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely. Thoroughly rinse the sprayer and measuring equipment immediately after use.
 
APPLICATION RATES AND TIMING
Crops:Winter and Spring Wheat
Diseases controlled:Leaf spot (Septoria tritici) and Glume blotch (Leptosphaeria (syn. Septoria) nodorum). Note: Activity against Septoria may be reduced in the presence of serious mildew infection
Timing:ROVER 500 contains chlorothalonil, a protectant fungicide best applied before disease onset or at the first sign of an attack.
A single application in the early spring at growth stage 30- 32 if conditions favour the development of Septoria tritici, may prevent the spread of the disease within the crop.
A later application from growth stage 33-65 may be used to protect the flag leaf and ear. For best results apply between growth stages 33-39.
Application rate:Apply ROVER 500 at 2 litres per hectare
Application volume:200 to 400 litres of water per hectare as a MEDIUM spray (as defined by BCPC) at a pressure of at least 2.0 bar
 
Crops:Barley
Diseases controlled:Leaf scald (Rhynchosporium secalis) [moderate control]
Timing:ROVER contains chlorothalonil, a protectant fungicide best applied before disease onset or at the first sign of an attack.
A single application as soon as disease is first detected in the crop.
A second application may be made before growth stage 51 (beginning of heading) if severe Rhynchosprium pressure occurs or if there is a risk of leaf spotting.
Application rate:Apply ROVER 500 at 2 litres per hectare
Application volume:200 to 400 litres of water per hectare as a MEDIUM spray (as defined by BCPC) at a pressure of at least 2.0 bar
 
Crops:Field Beans
Diseases controlled:Chocolate Spot (Botrytis)
Timing:Apply at early to mid flower and repeat two to three weeks later. Always make the first application before or as soon as disease is first seen and before it enters the ‘aggressive’ phase of infection. A two spray programme is essential.
The product must only be applied to field beans between BBCH61 (flowers open on first raceme) and BBCH69 (end of flowering). The product must only be used on beans that will be used as an animal feed item.
ROVER 500 will give moderate control of Chocolate Spot. However under conditions of severe disease pressure ROVER 500 may only give a reduction of Chocolate Spot
Application rate:Apply ROVER 500 at 2 litres per hectare
Application volume:200 to 400 litres of water per hectare as a MEDIUM spray (as defined by BCPC) at a pressure of at least 2.0 bar
