Abstract: A method for control of chemical products application made by aircrafts characterized by comprising the following steps step (101), starts by a pre-processing routine to initialize the application variables; step (102), the user informs which plots the chemical product application was supposed to be done; next, the system will load, from the desktop web application (4) to the application (1) through the internet (3), each plot polygon area, based on previously georeferenced imported files; step (103), load the application's sprays polygons from the GPS input files (6), the raw GPS log files, of the embedded GPS in the vehicle, is acquired from the GPS device by using a flash drive directly connected to the device's USB port and the user must use the export function of the GPS embed system to copy the files to the flash drive and after that the user upload the GPS input files (6) to the application (1) from the desktop web application (4); step (104), load from the GPS input files (6) the chemical product application and traveled path; step (105), collect the information about company, pilot/driver information; step (106), load, into memory for the financial report, the list provided by the user containing each applied product, dosage and costs; step (107), start processing the application report (7) with all needed information collected from the desktop web application (4) by the user and loaded into memory at the application (1); step (108), read, from the GPS input files (6), the application beginning/ending date and time; step (109), load, from the GPS input files (6), the application's average spray width; step (110), calculate the vehicle traveled distance by the traveled path from the GPS input file (6); step (111), calculate the chemical product application's average speed based on the GPS input file (6); step (112), generates, a new polygon based on the union between all the applied plots informed by the user that is the supposed goal target area for the application and all next calculations are done based on this resulting polygon; step (113), calculate the area in hectares for the resulting polygon from step (112); step (114), generates a new polygon resulting by the union between all chemical product application sprays; step (115), calculate the area of the resulting application spray polygon; step (116), calculate the resulting polygon for the overlap application spray areas; step (117), calculate the resulting polygon of no application area; step (118), calculate the successfully applied polygon; step (119), calculate the external application polygon; step (120), generate the financial report through the calculation of four indexes (hit, uniformity, failure and waste), using as a basis the calculations performed in steps (113), (115), (116), (117), (118) and (119) where: - hit rate is equal to the internal applied area (112) minus the internal area with dose error (116) divided by the total area of the plots (113); - uniformity index is equal to the internal applied area (112) minus the internal area with dose error (116) divided by the internal applied area (112); - failure rate is equal to the unapplied area (117) divided by the area of plots (113); - waste rate equals the applied external area (119) divided by the total applied area (114); Where internal applied area is the fraction of the total applied area located within the limits of the field (s) and internal area with dose error is the area applied internal to the field where there was a band overlap error (when the actual band width greater or less than recommended), featuring an area with underdosage or overdose of products; total plot area is the total plot area(s) based on the georeferencing of the property; unapplied area is the area inside the field that has not received application; external applied area is the fraction of the total applied area located outside the boundary(s); and total applied area is the total applied area recorded in the aircraft's GPS log; step (121), process the final report (7); step (122), save the final report (7) into the application database (2); step (123), generate a new identification hash code and a QRCode based on this hash code for the report (7); step (124), save all the resulting calculated polygons into application database (2) files in the server's file system; and finally step (125), save the final calculated information in the application database (2). t0 2", 4 c RELCMN SHEE
