  • Biopesticides Becoming More Than Just a Niche Product

    Growers are all too familiar with the vicious cycle of pests that develop a genetic resistance to chemical applications. As soon as researchers and growers find a chemical that works, genetic systems adapt and the pests find a way to survive. Then the costly cycle starts all over again. The solution to ending this cycle lies in the use of biopesticides as part of an Integrated Pest Management ...

  • Floating vegetative mats may help clean fishery wastewater

    The feasibility of using floating vegetation to remove nutrients from fishery wastewater is being tested by Agricultural Research Service (ARS) scientists. The researchers' long-term goal is to develop a system to treat the wastewater, return it to ponds for reuse, and use the nutrients to produce biomass or plant material. The floating mats act as filters to remove the nutrients from the water. ...
