What is zero application?
In view of better production and crop health in the cultivation of soybeans, one of the main grain crops in Brazil, producers follow the plan to apply fungicide during cultivation, seeking better control of pests and diseases.
A common practice among soybean growers is to carry out four fungicide applications throughout the soybean cycle, the first being before the crop canopy closes, on average at the V6-V8 phenological stage, the second application at the beginning of flowering (R1), the third application in R3 and the last scheduled in R4-R5.
However, there has been discussion regarding an additional application of fungicide before the inter-row closing application of the crop, between 20 and 30 days after planting (V3-V4), called zero application. This practice aims to preventively control the attack of diseases, at a time when crops are more susceptible to the impact of various pathogens, such as those that cause leaf spots, powdery mildew and Asian rust, for example.
