A computer program developed by Embrapa will help farmers control the optimal amount of pesticide to be applied to the crop . It is the system drops - version 2.2, which helps to calibrate the deposition of chemicals for use to be more efficient , avoiding damage to crops and preventing waste.

" The Drops is designed to assist farmers to obtain the appropriate parameters for deposition of pesticide on desired targets ," explains researcher Aldemir Chaim Embrapa Environment ( Jaguariúna , SP ) , who conceived the program with support from Embrapa Information Technology ( Campinas , SP ) .

Among the features incorporated in this version stand out a tool to cut certain area of the selected sample , the possibility to save the experiment in a format compatible for use of the results in spreadsheet ; resources to save and restore the entire experiment , with all images of the samples , and a tool for removing unwanted samples .

For targeted sampling is recommended to use water-sensitive business card available in the market . This card , with scanned image is processed by the program that offers various deposition parameters . With this, the farmer can decide on the best combination of nozzles, the solution volume , speed of application etc . , That give the maximum deposition in the desired target .

The calibration of deposition of spray droplets is important for the application of chemicals such as for organic products . The technology is recommended by Embrapa as a strategy for control of Helicoverpa armigera caterpillar that has surprised researchers by producers and their destructive , causing damage mainly to crops of corn, soybeans and cotton .

Drops The program is free and is available on the Web AgroLivre . Was also produced a manual of use , which advises on the technical specifications necessary for the operation of the software .
