In four months, the new model of climate monitoring, the Agriculture of the State of Rio de Janeiro (Pesagro), reduced by 42% the use of pesticides in tomato crops in the mountainous region, reported today (25) the Chairman of the Board, Silvio Galvão.

The devices collect information on the amount of rainfall, relative humidity and the average time that the vegetation remains on the surface with water. Every 15 minutes, the data are processed and made available to farmers on the Internet, said Galvão.

"The project is pioneering in Brazil. Though there are other countries broadcast stations, the idea of ​​monitoring equipment is unique in crops. Our job, as research firm, is to benefit the public, propose the consumption of healthier foods, since the producer by the monitoring system, applies the required dosage of pesticides in tomato plantation. Currently, the focus is on tomatoes, but for 2014 we go to the bean, cauliflower, cotton and coffee, "said agronomist. The tomato is one of the cultures in which one uses more pesticides.

Brazil is one of the largest buyers of the world's pesticides and poisoning by these substances are increasing among rural workers

According Galvão, a 42% decline in the use of pesticides also reduces the cost of producing a crop, besides reducing pollution in the environment and the waste product in the fruit. Every thousand feet of tomato, it takes $ 300 with the purchase of pesticides and 4,800 liters of clean water at planting.

In this initial phase, the project has ten stations, with the ability to monitor and interpret data in a radius of five kilometers each. From April, ten more shall come into operation on properties in the municipalities of Paty's Ensign, Brooms and Duas Barras, in southern Rio. The project cost is still considered high, around R $ 24 thousand per year for data analysis, equipment, professional, and £ 2000 for maintenance.

At the moment, the interest is in the farmers' associations, in search of cheaper model. Our goal is to get to the second half with 50 stations [weather]. The work of the technical or agricultural agronomist will be preserved and equipment, just to improve work in the field, "said Silvio Galvão.

Currently, Brazil is one of the largest buyers of the world's pesticides and poisoning by these substances are increasing among rural workers, concluded Galvão.
