Triziman was presented by UPL in Brazil as a new generation fungicide that combines three active ingredients: azoxystrobin, ciproconazole, and mancozeb. It fosters a multi-site action, interfering in mitochondrial breathing, and acts as an inhibitor of ergosterol biosynthesis with two systemic active ingredients.
According to UPL, the product presents a “complete fungicide action” due to its inhibition of the spore germination, penetration and development of the foliar tissue, and its sporulation. “Because of its differentiating action, it becomes an excellent option for the resistance management and control of Asian soybean rust (Phakopsora pachyrhizi),” explained Rafael Pereira, senior innovation manager at UPL.
Professor Erlei Reis of the University of Passo Fundo and part of the Eagle Team, said the number of fungicide users that have adopted the technology of a multi-site use has increased. However, all soybean producers need to comprehend the uses of this technology to efficiently control the Asian Rust on soybeans.
“The use of multi-site came in England in the decade of the 70s, when the disease control on potatoes, tomatoes, and grapevines threatened producers. In the following decade, the first cases of resistance were found that did not have more efficiency. So they started to sell mixtures with Mancozeb. Looking at the past scenario, I understand that the situation will just be normal when 70% of the soybean area in Brazil is treated properly with the recommended  quantity of applications, product rotation, and correct management, among other care techniques,” said Erlei.
Luis Carrelga, professor at the Rio Verde University, highlighted the importance of good practices of management for soybeans: “It is important to understand that the resistances of the site-specific products are there. Carboxamides, strobilurines and triazole are products that do not employ more control of 80%, nor mixtures or singles. So to have a smaller population of resistant crops, we have to put other things for efficiency. And the best that we have today are the multi-site fungicides. This acts on a specific point of the fungi, and this shrinks the risk of resistance. We do not have to avoid the resistance because it has already happened, but the multi-site has to be recommended and used to stabilize the problem of resistance, and see that it does not worsen.”
