Cuprablau Z

Special features that make it competitive:

• Broad spectrum fungicide
• Bactericidal action
• Long – term resistance
• Does not affect population of beneficial organisms under normal field conditions
• Beneficial side effects – improved maturation of annual grapevine wood and improved grape berry skin hardening which minimizes the risk of infection, that results in grape decay
• Highly recommended for conventional, integrated and organic farming pest control

Formulation: Wettable Powder (WP), green to bluis green

Contains: 350 g / kg Copper (Cu) from Copper Oxychloride (COC).

Use

Cuprablau Z is a preventive contact fungicide used to control diseases of most important agricultural crops such as  apples, grapevines, potatos, tomatos,...

Spectrum of activity

Cuprablau Z is a fungicide used to control the following diseases:

Vineyards:

-       Downy mildew (Plasmopara viticola) - recommended concentration is 0.3%.

At the same time it controls rot brenner (Pseudopeziza tracheiphila) and black rot

(Guignardia bidwellii).

Orchards:

-          Apple and pear scab (Venturia spp.); apple canker (Nectria galligena); collar rot (Phytophthora cactorum) and bacterial disease called fireblight (Erwinia amylovora).

Recommended treatment: first pre-spring spray in A - C phenophase with recommended concentration of 0.8 %; second spray in C3 with recommended concentration of 0.25 %.

-          Pear fire blight (Erwinia amylovora).

Recommended treatment: in order to achieve best results, sprayings should be done in 7 - day intervals with recommended concentration of 0.06 %, when trees are starting to blossom and until they reach full blossom.

Shot hole on drupes (Clasterosporium carpophilum) - recommended concentration is  0.8 %.

Recommended treatment: early autumn spray - when the trees start losing their foliage; second spray - after the trees have lost their foliage, which also acts preventively towards the occurrence of blossom blight (Monilia laxa) next year; spring spraying has to be done during germination in A - C phase.

-       Peach leaf-curl (Taphrina deformans) - recommended concentration is 0.8 %.

Recommended treatment: first spray can be done in autumn, after the trees have lost their foliage, or twice in winter - no later than during the bud swelling phase, which minimizes potential occurrence of shot holes and partly of peach scab.

-       Peacock spot on olive (Cycloconium oleaginum) - recommended concentration is 0.3 %.

Recommended treatment: early spring spray - before the trees start to blossom.

Hop:

-       Downy mildew (Pseudoperonospora humuli) - recommended concentration is between 0.25 % and 0.30 %.

Recommended treatment: before the blooming phase, based on prognostic service instructions; compulsory spray has to be done at the beginning of the blooming phase and before the blooming phase is finished; if done after the blooming phase, special prognostic service instructions have to be followed.

Field crops and garden vegetables:

-       Potato and tomato blight (Phytophtora infestans) - recommended dose  is between

3 to 4 kg/ha. At the same time it controls tomato leaf and glume spots (Septoria lycopersici).

Pre – harvest interval

14 days for hop, potato and tomato (outdoor and in the greenhouse),

28 days for grapevine,

for orchards is ensured with the time of use.

Compatibility

Cuprablau Z is compatible with most commonly used fungicides and insecticides. However, the fungicide cannot be mixed with pesticides that cause acid reaction.

Phyto - toxicity

When used in recommended doses at recommended times Cuprablau Z does not cause any burns or phyto – toxicity on the crops.

Environment protection

When used, we have to make sure that it does not contaminate waterways, lakes, wells and water sources by spraying the area which is at least 20 metres away from them.
