Rotam do Brasil announced the launch of Rotaxil, a fungicide to combat white mold, a disease that affects several crops in the country. It is a product based on the liquid formulation procymidone, indicated for foliar applications (R10) and (R1+10 days) just before flowering. It aims to give preventive protection to plants against white mold. 
 
According to the soybean division of the Brazilian Agricultural Research Company (Embrapa), the use of active principles procymidone and carbendazim when combating white mold with on-stage applications of R1 and R1+10 days controls 99% and 98% of the disease, respectively. The experiment was conducted on commercial soybean crops with a historic incidence of fungus in the municipality of Pitanga in the state of Paraná.
 
The presence of white mold was recorded to be higher, with an average of 41.3% in the treatment without control. “This work and others that we have analyzed, and will release soon, confirm that Rotaxil reduces significantly the production of Sclerotinia sclerotiorum, contributing to the management of the disease in the soybean crop,” noted Luciano Kajihara, senior specialist for Technical Development and Research at Rotam do Brasil.
 
During the 2017/2018 seasons, the white mold was worrying producers in the South and Cerrado in Brazil. The disease is caused by the fungus Sclerotinia sclerotiorum and presents high yield loss potential between 30% and 70%, especially when management measures are not correctly taken.
 
This is a host disease in more than 400 species of plants and has the propensity to appear in higher areas, above 600 meters of altitude, in conditions of high moisture and temperatures ranging between 10°C and 21°C. Besides this, owing to the difficulty in eradicating the survival structures of the pathogen, the control requires a joint and preventive adoption of crop management, biological control and chemical control of the pathogen. 
 
“The fungus is capable of infecting any part of the plant; however, the most vulnerable stage of the soybean crop was the stage of full flowering. So, it is important to conduct prevention at stage R1, according to our program guides,” explained Kajihara.
