Clik Extra Spray On Elanco **

ClikExtra (for fly control in sheep)

ClikExtra is made by Elanco.

It contains 65g/l of Dicyclanil (stronger than Clik, longer protection than Clik)

It is for the longer term prevention of blowfly strike in sheep

It can be used on sheep with any length of wool, including off-shears

It comes in 5L and 20L. It is ready-to-use, water based.

ClikExtra is applied as a spray-on, through an applicator with a fan spray nozzle, ideally an Elanco one. Applicators are always washed out with water.

See label or website for application dose rate and directions, as they change depending on the area to be targeted for protection.

Protection period Up to 29 weeks

ESIÂ 63 days

Wool withhold Do not use less than 3 months before shearing

Re-treatment interval Do not use again within 9 weeks

Dicyclanil is an Insect Growth Regulator (IGR) so it will prevent maggots that are laid on the sheep from growing, so they cannot cause damage to sheep, and in turn starve and die

It will not kill existing maggots, therefore another product must be used on existing strikes  - best is Extinosad Aerosol or Extinosad Eliminator liquid.

Any fly product can have reduced efficacy in certain conditions. Heavy rain and high fly pressure during the protection period can reduce length of protection.

There is known resistance to Dicyclanil, so producers should be aware of this, and therefore expect that the stated protection period may be reduced.

They should also consider using other active ingredients across a fly season if re-treatment is needed (such as Avenge or Jetaway, but be careful with withholds)

Significant soiling with dags, urine, mud, dust can reduce efficacy, as can scouring post application. A light crutch before treatment is recommended where significant dags are present.

Clik can also be used at mulesing and marking time, to protect wounds from flystrike during the wound healing process. See label for directions. Be sure to apply on the edges of the wound, overlapping 25mm out into the wool (products like Trisolfen or Extinosad aerosol or spray bandage go on the wound itself)
