Gorse and Broom are the most common pest plant on South Island farms. They take over useable land and provide excellent cover for animal pests to live in. Take control of your gorse and broom by employing the services of D M Holdings. Our qualified, experienced operators have the best equipment available with which to tackle any sized gorse/broom job.

Using one of our 4wd mounted rigs, our ATV spray rigs or knapsacks, we can access any location safely, with minimal ground impact. We choose to use Envirodye in our spray mix, so results can be visible from the time we start, and you, the client can see value for your money.

      Aquatic and water way spraying

      D M Holdings can spray river weeds, river beds or banks, as well as drains or ditches for plant pests.

      We can spray willows on rivers or invasive weeds such as Glyceria Maxima from our own vessel or from vehicles on the bank.

      Drains and ditches need to be kept free from grasses and weeds to ensure water flows freely when heavy rain strikes. Contact us to arrange an onsite appraisal of your plant pest issues.
