Use of adjuvants in sprays increases coverage gains

Application technology in agriculture can be defined as the set of knowledge that allows the correct placement of a biologically active product on the soil or plant. The application efficiency depends on several factors such as temperature and relative humidity, machine and applicator (spray tip and application speed) and the solutions to be applied (types of formulations and use of adjuvants).

The use of adjuvants in spraying has become a very common tool in the field to make this application more efficient. It is a product added to assist or modify the action of a phytosanitary product or a tank mixture to ensure the effectiveness and safety of the application process.

Adjuvants are classified into different types, according to their functions and the set of components and their balance within the formulation. For each need, the most suitable one must be chosen, with the help of specialized professionals.

Surfactants are used when there is a larger leaf surface to be covered and there is a need for product emulsification. The stickers accelerate or increase the absorption of the spray solution into the leaves. Humectants reduce the rate of droplet evaporation. Spray conditioners are recommended when there is a risk of degradation of assets due to water characteristics. Drift reducers reduce the formation of very fine droplets and/or increase their size. And defoamers reduce foam formation or eliminate it if necessary.

Fertiláqua has adjuvants that bring together the appropriate balance of functional components for Brazilian agriculture, with the benefits of surfactants, emulsifiers, humectants, adhesives and antifoams and the reduction of drift potential, resulting in more efficient spraying.

“Tests we carried out on several producers showed that the coverage gain, in different environmental conditions, increased by an average of 85% with the use of adjuvants. Spraying was carried out in the states of São Paulo, Paraná, Goiás and Santa Catarina”, explains Eduardo Cancellier, market development coordinator at Fertiláqua.
