Q: Will this kill primrose

9 months ago
1 Answer
  • A: Hello, thank you for your question. Although primrose is not included in the list of controlled weeds in the manual, herbicides with Diquat dibromide as the active ingredient, like Airmax Ultra PondWeed Defense, are known to be effective on water primrose. Multiple treatments may be needed for dense growth, and best results are achieved when the plant is actively growing and before it flowers.

Q: Will it kill fish

3 years ago
1 Answer
  • A: This can be used in fishing ponds. However, in this case, you should only treat about 1/4 to 1/3 of your pond at a time to assure you don't deplete all the oxygen in the water for the fish. Treatments should be spaced about 10 - 14 days apart.
