Biological fungicide Rizoderma to be launched in Argentina
Jul. 28, 2014
Argentinian scientists announced the introduction of the first "bio-input" to treat fungus diseases developed in Argentina. Rizoderma (Trichoderma harzianum) is a biological fungicide that allow the control of nearly 40% of the soil phytopathogens that affect wheat and other winter crops.
The product is applied directly on the seed and will be launched to the market by Rizobacter company. The company was a partner on the joint development with the Institute of Microbiology and Agricultural Zoology of Argentina's National Institute of Agricultural Technology (INTA).
According to the company field experiments in pampas region, yields increase was 190 kilos per hectare after a bio-fungicide application. Different than other chemically synthesized products, this bio-input does not eliminate the beneficial flora in the soil.
Laura Gasoni, an expert at INTA, who headed the research and studied the issue for two decades, said that the function of the new product is not "to destroy the pathogen completely, but limit the damages". Similarly, the tests confirmed the control of phytopathogenic Fusarium to “an acceptable level", she said.
Comparing to other similar inputs available in the Argentine market, the specialist said that those are not biofungicides, but biofertilizers that are intended to favor the vegetal growth.
According to the expert, the product has a direct action that allow "the avoidance of the pathogen attack by different action mechanisms". She also suggested to make an adequate seeds treatment previous to the planting and that "assures a major emergence of plants and better yields".
The studies have proven the biofungicide is able to be complemented with other chemical products of common use on wheat cultivars. "In most cases, incompatibilities were not found", affirmed Gasoni.
Currently, Gasoni highlighted that the research continues in the field to extend the product efficiency. She mentioned "There are projections to extend the biological control to other crops like soybeans". For that, "it would be necessary to isolate a beneficial organism specific for the phytopathogen control and soon to develop an product that includes it".
