CROP SPECIFIC INFORMATION
Rates of Use
Apply ALTO ELITE at 2.0 litres/ha.
A maximum total dose of 4.0 litres/ha ALTO ELITE can be applied to crops of winter wheat, winter and spring barley, winter and spring field beans and combining peas.

 

Powdery Mildew (winter wheat, winter and spring barley) Apply ALTO ELITE at the start of mildew development. A repeat application of ALTO ELITE can be made if necessary. Septoria spp. (winter wheat) ALTO ELITE controls septoria (S. tritici and S. nodorum). Where infection may occur following a “rain-splash event”*, apply ALTO ELITE as soon as possible afterwards to prevent visible symptoms developing. It is important to protect both the second leaf and flag leaf. * “Rain-splash event” is defined as 10 mm or more of rain in up to three consecutive rain days i.e. days with 1 mm or more of rain; 5 mm of rain in any one day may be sufficient where stem elongation is incomplete or in short or thin crops. ALTO ELITE provides prolonged protection from re-infection but a repeat application may be made if necessary. Yellow Rust (winter wheat, winter and spring barley) Apply ALTO ELITE when yellow rust is first detected, before 1% of any leaf is infected. ALTO ELITE provides prolonged protection from re-infection. A repeat application may be made if necessary. Brown Rust (winter wheat, winter and spring barley) Apply ALTO ELITE when rust is first detected. ALTO ELITE provides prolonged protection, but a repeat application may be made if necessary. Eyespot (winter wheat and winter barley) When applied between GS 30-34 to control other diseases, ALTO ELITE gives a useful reduction of eyespot. Where high levels of eyespot are probable and to ensure that both ‘Rye’ and ‘Wheat’ types of eyespot are well controlled and that there is no build up of the ‘Rye’ type, consider using in a programme with another eyespot controlling fungicide.

Rhynchosporium (winter and spring barley) Apply ALTO ELITE as soon as the disease becomes active. A repeat application of ALTO ELITE can be made if necessary. Net Blotch (winter and spring barley) Apply ALTO ELITE as soon as the disease becomes active. ALTO ELITE only gives moderate control. Where disease pressure is particularly high, consider using in a programme with another net blotch controlling fungicide. A repeat application of ALTO ELITE can be made if necessary

 

ALTO ELITE contains 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.

 

Chocolate Spot ALTO ELITE at 2.0 litres/ha applied at early flower (GS 203) will give moderate control of chocolate spot if active disease is present. A repeat application should be made 2-3 weeks later if the disease is still active.

 

ALTO ELITE provides prolonged protection. Apply ALTO ELITE when rust is first detected. A repeat application may be necessary. Where bean rust continues to develop and further control is necessary, an alternative product must be used.

 

Grey Mould Apply ALTO ELITE at 2.0 litres/ha at early flower (GS 203) if active disease is present. A repeat application should be made 2-3 weeks later if disease is still active.

 

TIMING OF APPLICATION
The most effective control of diseases is achieved by applying ALTO ELITE when disease is first active.
ALTO ELITE may be applied before caryopsis watery ripe stage (GS71) on winter wheat, before beginning of anthesis (GS60) on winter and spring barley and six weeks before harvest on winter and spring field beans and combining peas.

MIXING AND SPRAYING
Good spray cover of the target is essential. Ensure the sprayer is in good condition and that the correct nozzles are fitted and working correctly.
Add half the volume of clean water to the spray tank. Add the recommended quantity of ALTO ELITE. Agitate while topping up the spray tank and continue agitation during spraying.
Wash out all spray equipment with water immediately after use.

 

Apply as a MEDIUM quality spray as defined by BCPC*. A pressure of 2-3 bars should be used. * For details see Nozzle Selection Handbook published by The British Crop Protection Council.

 

The boom height should be adjusted so that the output from alternate nozzles meets just above the crop.

 

Apply ALTO ELITE in 200-400 litres of water/ha. The higher spray volume is recommended where the crop is dense to ensure good penetration to the lower leaves and stem bases.
