Trichoderma harzianum fungus has been in use in Brazilian agricultural systems as a micro-biological fungicide for the last 10 years. Now, Koppert do Brasil has announced that the product Trichodermil SC 1306 can also be applied as a microbiological nematicide to the sugarcane crop, for combating fungi and phytopathogen nematodes directly.
The registration of Trichodermil SC 1306 with the double fungicide and micro-biological nematicide function was released through the approval of the Ministry of Agriculture, Livestock and Supply (MAPA). The alteration in the recommendations for the product use occurred through the publication of a notification No. 77 in the Official Union Gazette on September 18, 2017.
According to Luciano Olmos Zappelini, production and development manager at Koppert do Brasil, the extension in the use of the micro-biological fungicide/nematicide is a result of “repeated experimental fields, as well as the practicability of agronomic essays against the target Pratylenchus zeae.”
“Through innovation in research in the face of different modes of action of the biological agent Trichoderma harzianum, strain 1306, it was concluded that some metabolites and enzymes have direct action over the phytopathogen nematode populations, among them the Pratylenchus zeae,” he explained.
Trichodermil SC 1306 was the first product to be registered in Brazil based on the fungus Trichoderma harzianum and was obtained by Koppert as a microbiological fungicide in 2007. Field data has shown the effectiveness of the product in the control of various targets, such as Fusarium, Rhizotonia and Sclerotinia on diverse grain crops, fruits and vegetables.
“Its mode of action occurs in different ways, among them is the fungi phytopathogen control, as Trichoderma has a high competence in colonizing soils and root systems. The Trichoderma has the ability of parasitising scleroids, hyphae and fungi that cause diseases in the soil, enabling and contributing significantly to the reduction in the incidence of plague. The nutrient solubilization in the soil makes them available to plants and is attributed to Trichoderma action at the rhizosphere,” he concluded.
