Enter your drench efficacy (%) results in the fields below. Where you have no data, leave the field empty.
The data (above) for single-actives will be used to predict % efficacy of combinations (below). ‡ Blank result cells indicate insufficent data to calculate a prediction.

*Closantel. Bear in mind that the amount of closantel per dose is not the same for all products containing closantel, so results of efficacy testing (and predictions based on these results) can vary between products, even if the label dose rate is used.
**Derquantel and oxyclozanide do not come in single active formulations.
‡ There are other drench products with two actives that are not listed here because they are mixtures, not combinations. These include either triclabendazole (which targets liver fluke) or praziquantel (which targets tapeworm). With such mixtures, only one of their actives works against roundworms. Therefore, the efficacy of these mixtures against roundworms is the same as their single-active component for roundworm.
Testing systems are very useful, but imperfect. When combined with biological systems, test results provide approximations and may vary from one test to another. For this and other reasons, WormBoss recommends regular DrenchChecks in between 2–3 yearly DrenchTests.
