Combination drenches are an important tool to manage or delay drench resistance, achieve on-going productivity and prolong the productive life of the three main drench families.
Combinations are more effective than single active drenches because worms that are resistant to one active are killed by the other active(s)[12,13]. This greatly reduces the probability of resistant worms surviving the drench and minimises the risks of drench resistance[9,14,15].
The interactive animation below shows how combination drenches works.
