Weed control is one of the most important steps in agricultural production. The sales of herbicides ranks first among the global market share of pesticides. However, the use of a large number of chemical herbicides has caused environmental problems such as water quality degradation and soil pollution, especially the constant occurrence of resistant weeds, which has brought great challenges to agricultural production. According to statistics, as of 2018, a total of 495 cases (biotypes) of resistant weeds have been reported worldwide, involving 255 types of weeds. In China, from the first report of weed resistance in 1992 to 2018, a total of 44 resistance cases have been reported, and the trend of resistant weeds is not optimistic.

With the increase of global environmental awareness and the need for sustainable agricultural development, the development of bio-herbicides with good environmental compatibility, high selectivity and strong biological activity is urgently needed. This trend has become inevitable for the development of contemporary pesticides. Although there are few mature bio-herbicide products on the market, bio-herbicides have become one of the important research and development areas for scientific research institutions and biological pesticide companies. In this article, we hope to help people better understand this market and better grasp the development trend of bio-herbicides by sorting out the current status of the global market, the major bio-herbicide companies and currently available products…READ MORE

Marrone Bio Innovations Inc. (USA): In 2018, Marrone Bio Innovations (MBI) submitted the registration package for its first bioherbicide, MBI-014, to the US Environmental Protection Agency (EPA), which brings prospect to the market. It is understood that MBI-014 is a water-dispersible microbial herbicide made from a new species of heat-killed bacteria, Burkholderia rinojensis (strain A396), and has a new mode of action. It has post-emergent herbicidal activities across a range of weeds, especially weeds in the pigweed family. At present, the company is still conducting a series of studies on its optimal dose, adjuvant package needed and further expansion of the spectrum of targeted weeds. The product is expected to be available around 2020.
