RESISTANCE PREVENTION

Risk of resistance? YES but rather low, mainly in Australia.

It has been shown that houseflies & blowflies resistant to cyromazine (another IGR vastly used for blowfly strike prevention) have some degree of cross-resistance to dicyclanil. However, resistance of blowflies to cyromazine is still quite unusual. It has been reported for Lucilia cuprina in a few locations in Australia, but so far not in the UK, other EU countries, South Africa or New Zealand. In those cases of cyromazine field resistance reported in Australia resistance factors were very low (about 2.3 for cyromazine, 1.3x for dicyclanil) and the concerned products were still providing protection according to registered label claims.

COMMENTS

SrikeForce-S  Spray-on/Pour-on for sheep from JUROX is a ganeric version of CLIK (introduced by NOVARTIS AH in the late 1990s).

Dicyclanil is an insect development inhibitor introduced by NOVARTIS AH in the late 1990s. It has a very specific efficacy againts dipteran larvae. So far it is exclusively used in sheep, and not at all in other livestock, pets or agriculture.

For those visitors that have reached these depths of parasitipedia.net here's a personal message. I was very heavily involved in the discovery and development of dicyclanil and CLIK in the 1990s during my years in NOVARTIS AH.
