WormKill - the basics
WormKill is a sheep worm management program for the summer rainfall area of north eastern NSW with annual rainfall approximately 650mm or above and north of a line from Sydney to Mudgee. (See map).
The program was first launched in 1984 but has evolved since then, particularly because drench resistance has become worse.
