The use of adjuvants has become a fundamental part of rural producers’ daily lives. As explained by Ubyfol's technical market development manager, João Alves Silva, this practice aims to provide conditions to minimize losses at the time of application, such as reducing drift and foam, in addition to providing better spreading on the leaf surface.
In addition to reducing losses from the products that will be applied, the use of a multifunctional adjuvant contributes to better efficiency of the active ingredients contained in this spray solution. This results in better conditions for the cultivated plant to express its productive potential and consequently increase productivity.
The reduction in losses associated with better contact and distribution of the active ingredient on the target surface (due to more perfect spreading) provides greater efficiency in this application. “This, depending on what is being used, will result in increased control of pests, diseases and/or weeds as well as better absorption by the plant of possible nutrients that are being applied at that time”, explains the manager.
Some attributes are desirable in an adjuvant: spreading effect, drift reduction and foam reduction. These products generally have one or two of these characteristics in their formulation. Ubyfol's R&D (Research and Development) team managed to bring three of them together in a single formulation. The adjuvant is multifunctional and has non-ionic and organosilicone surfactants in its chemical composition. Furthermore, it is recommended for all types of crops and spraying. “Disperse Ultra helps to reduce losses due to drift, favors greater contact between the droplet and the target as it has a high power to break the surface tension of that droplet, and consequently better spreading of the droplet. Furthermore, this formulation also has the effect of reducing foam formed in tank mixtures, reducing possible losses that this may cause”, says Alves.
In order to evaluate the spreading effect of Disperse Ultra, an experiment was carried out on sugarcane cultivation. Ubyfol obtained the following results for 3 different types of applications: one using only pesticides, the other with pesticides + Disperse Ultra and finally, pesticides + competing product on the market. “The wetting area with Disperse Ultra reached 1,19 square millimeters (mm²), while the application without any adjuvant resulted in 0,87 mm²”, details the manager. The evaporation time with the Ubyfol adjuvant was 69 seconds, while the application without this type of product evaporated in 48 seconds, and the competitor in 60.
Another research with the product was carried out in soybeans, analyzing the spread rate when applying insecticides to control bedbugs. 4 types of applications with chemicals on the market were evaluated. The percentage of insect control using Disperse Ultra reached 72% while the same insecticides without the adjuvant controlled 64%, that is, 19% more application efficiency.
These results prove that the adoption of this technology favors a better effect of the pesticides applied, guaranteeing greater agronomic benefits and increases in productivity.
