An emulsifiable concentrate containing 90 g/litre metconazole. A fungicide for the control of a wide range of diseases in winter and spring wheat, durum wheat, winter and spring barley, triticale, rye, oilseed rape, peas, field beans and lupins; and a spring plant growth regulator in oilseed rape.
 
DIRECTIONS FOR USE
uventus is a broad spectrum fungicide with curative and protectant activity, which can be used on all commercial varieties of winter and spring wheat, durum wheat, winter and spring barley, triticale and rye. Juventus can also be used on oilseed rape, field beans, combining and vining peas and lupins. When applied to oilseed rape in the spring, Juventus can provide plant growth regulation in the form of a reduction in crop height.
 
Restrictions/Warnings
Do not apply to oilseed rape crops that are damaged or stressed from factors such as previous product use, adverse weather conditions (e.g. drought, frost or waterlogging), nutrient deficiency or pest attacks.
Juventus is formulated specifically for use on oilseed rape and legumes. The addition of further adjuvants is not advised.
Juventus should not be applied with pyrethroids to flowering oilseed rape.
Ensure the sprayer is free from previous chemical residues that may harm the crop. Use of a detergent cleaner is advised before and after use.
Avoid spray drift on to neighbouring crops and field margins.

 (C = full control MC = moderate control GR = good reduction R = reduction).
Time of Application Apply as soon as diseases start to develop in the crop and repeat as required.
Application at an early stage of mildew development (not more than 3% infection on any green leaf) will give moderate control. Where mildew has become established, the use of a specific mildewicide will improve control and help prevent the development of resistant strains.
For optimum results on yellow rust apply before any leaf has more than 1% infection or as a preventative treatment on susceptible varieties after the flag leaf has fully emerged (GS 39).
Good reduction of ear Fusarium may be achieved when applied between full ear emergence and anthesis complete (GS 69).
For control of brown rust treat susceptible varieties as soon as rust is seen and spray more resistant varieties before any of the top three leaves have more than 1-2% infection.
Spray as soon as net blotch is seen on any of the top three leaves. A further treatment will be necessary where disease is well established Rate of Application 1.0 l/ha
 
OILSEED RAPE(All varieties of oilseed rape may be treated. Disease control Juventus provides control of Alternaria, and a reduction of phoma leaf spot, phoma stem canker (Phoma lingam) and light leaf spot.)

Time of Application Apply as soon as diseases start to develop, and repeat as required.

Rate of Application 0.8 l/ha.

Crop height reduction When applied to oilseed rape in the spring, Juventus can provide plant growth regulation in the form of a reduction in crop height.

Time of Application Apply during stem extension in the spring, once the oilseed rape crop is actively growing (GS 31-51).

Rate of Application 0.8 l/ha.

PEAS, BEANS LUPINS

(All varieties of peas and field beans may be treated. Consult processor before using on vining peas grown for processing. Safety to lupins has not been established. If possible, a small area of the lupin crop should be treated before treating the whole crop. Disease control Juventus can be used for the reduction of Ascochyta and Mycosphaerella species, the reduction of Botrytis and the control of rust on peas. )

Resistance Management
Juventus contains metconazole, a DMI fungicide. Resistance to some 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 in DMIs contact your agronomist or specialist advisor, and visit the FRAG-UK website.
Cereal Powdery mildew strains with decreased sensitivity to triazoles are common in the UK. Where these occur or develop, Juventus may not give satisfactory control.
For crop/pathogen situations where repeated spray applications are required, alternation or mixtures with an effective non cross-resistant fungicide are recommended. Fungicide use does not replace the need for non- chemical cultural control methods e.g. resistant crop varieties, good agronomic practice, plant hygiene.
 
Mixing
Never prepare more spray solution than is required.
Three quarters fill the tank with water and start the agitation. To ensure thorough mixing of the product, invert the container several times before opening. Add the required quantity of Juventus to the spray tank while re-circulating. Fill up the tank with water and continue agitation until spraying is completed.
On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add washings to spray tank at time of filling and dispose of container safely.
Application
In cereals apply Juventus in 200 to 300 l/ha water In oilseed rape and legumes apply Juventus in 200-400 l/ha water.
Apply as a MEDIUM spray, as defined by BCPC. In dense crops use the higher volume to achieve adequate penetration and good coverage of the crop To ensure optimum spray coverage and minimize spray drift, adjust the spray boom to the appropriate height above the crop, in according to guidance provided by the sprayer and/or nozzle manufacture.
Sprayers should be thoroughly cleaned out immediately after use.
Qualified approval Juventus may be applied in reduced water volumes as specified in the table below, although efficacy at this reduced volume has not been evaluated. Application of this product at reduced-volume is at user’s risk with regard to biological efficacy.
