Seed treatment with fungicide reaches efficiency above 98% without phytotoxicity

According to phytopathologist Rita de Cássia Santos Goussain, the fungicide, Certeza N, from Ihara Brasil showed a control efficiency above 98% during a blotter test.

In the assay, the fungi complex of Cercospora spp., Colletotrichum truncatum, Corynespora cassiicola, Fusarium spp., Macrophomina phaseolina, Phomopsis spp., Rhizoctonia solani and Sclerotinia sclerotiorum successfully achieved controlled.

In addition, Goussain also pointed out that the ″phytotoxicity of the product was not observed during a paper roll germination test (TPG), as well as in the length of seedlings, indicating that the ingredients, Thiophanate-methyl and Fluazinam, contained in the product can be used for the treatment of soybean seeds targeting these fungi.″

The fungicides ″guarantee protection against fungi present in the seeds and the soil, as various fungi are known to be pathogens of soybean seeds,″ she added.

″However, before seed treatment (TS), it is important to detect which fungus is present and find out the history of occurrence in the planting area. One should also be aware of the fungicides registered for TS in soybeans with proven efficiency,″ she further added.

Several groups of fungicides are registered for use against the main targets of treatment for soybean seeds in Brazil, including Benzimidazole, Fluazinam, Metalaxyl, Fludioxonil, Triazole, Thiram and Dimethyldithiocarbamate.

According to Ihara, Certeza's differential is the Ultra High-Performance Sticker (UHPS) technology, which ″gives offers adhesion to seed and resists washing off by rain. As a result, it provides greater control efficiency and a longer protection period.″
