Diagnosis and methodological description proposal for scientific-technological articles relational to assessment of herbicides application
Chemical control is a viable tool and practically essential in the management of weeds control. However, insufficient details about application methods of pesticides have been observed in most scientific publications that deal with herbicides utilization. With the objective of verifying the presence or absence of basic information about herbicides application found in scientific papers, as well as to propose a criterion of minimum description needed with information that may guarantee better repeatability of methods and techniques used, it was conducted a survey in 200 papers published in national and international periodic. It was observed that minimum descriptions required about herbicides application technology have not been observed. Besides all papers showed the used application rate (L ha-1), outstanding with insufficiency the description of droplets spectrum formed by sprayer, with lack of information in 84.5% of evaluated works; work pressure (15.5%); spray solution concentration (20.5%); distance and position of nozzles in relation to the target (58.5%) and meteorological conditions, with median absence (temperature, air humidity and winds speed) of 62.6% in evaluated papers. In order to rescue the importance of criterion description about herbicides application technologies in scientific papers, it was elaborated a simplified methodological description, that offers to maximize the security and fidelity in information’s reproduced referred to weeds control.
