How to treat phytophthora root rot in soybean



A destructive fungal infection called the Phytophthora root rot, which is widespread and causes inconsiderable losses of soybean output every year, is the reason of its infection. The root-rot disease’s oomycete, which thrives in wet soils with poor drainage, makes its way to the roots and stems of soybeans through heating, which then leads to the rotting of the plant. An integrated approach that blends cultural methods with resistance genes and chemicals is required for an efficient management of genetic recombination of the virus in plants (PRR). The ultimate goal of this blog is to provide a list of comprehensive activities that the farmers may take to lower the effects of Phytophthora root rot in the process.

Pick varieties that are non-hazardous

Genetic engineering supplies resistance traits of soybean cultivars, which are immune to Phytophthora sojae (the first and major stage of PRR). In most cases, they depend on their quality resistance to different races of the disease for the evaluation of their varieties. It is critical for farmers to select crop species that carry the line of resistance to diseases that are grouped in the same race as those that exist in their area. There are two types of resistance that can be found in soybeans: R-gene, a gene that renders crop race specific resistance and partial resistance, which is a broader protection but less efficient than the first one. 

Provide the Drainage channels with the current road. 

Because Phytophthora sojae is trophic in wet conditions, improvement of drainage reduces excess moisture and thereby reduces the probability of infection. Excess water may be drained out from the soil by setting up techniques like installing tile drainage systems or construction of a raised bed. 

Administer Water and Fertilizer Management

It is essential to have effective irrigation management in order to prevent PRR. In order to keep the soil from becoming saturated, it is very important to avoid over-irrigation, particularly during times of severe rainfall. In addition, the application of a balanced fertilization, with a special emphasis on the regulation of nitrogen levels, has the potential to improve plant health and reduce the likelihood of disease. Plants that are in good health are better able to withstand attacks from pathogens and more quickly recover from diseases.

Apply Biological Control Agents

Biological control agents offer a natural alternative to chemical fungicides and can enhance plant resistance against diseases like PRR:

  • Trianum Shield: Based on the fungus Trichoderma harzianum, Trianum Shield promotes healthy root systems by colonizing plant roots and protecting them against pathogens. It can be used as a seed treatment or applied directly to the soil.
  • Trichoderma Harzianum: This product directly targets pathogens with its aggressive colonization and by enhancing plant immune responses and is a phytophthora root rot fungicide. It is particularly effective in combating root rot diseases.¬†
  • Bacillus Subtilis Fungicide: Featuring Bacillus subtilis, thats forms a protective barrier on plant surfaces, which inhibits the growth of fungal pathogens. It can be applied to foliage or soil to suppress the development of PRR. Discover fungicide for phytophthora root rot.

Final Thoughts

A method that incorporates multiple facets is necessary for the effective management of Phytophthora root rot in soybeans. The impact of this disease can be considerably mitigated by growers by the implementation of resistant varieties, the enhancement of soil drainage, the implementation of crop rotation, the prudent management of water and fertilization, the utilization of fungicidal seed treatments, and the meticulous monitoring of fields. The most important thing is to maintain vigilance and take the initiative when putting these tactics into action in order to guarantee the well-being and productivity of soybean crops.
