GUEDES, Jerson V. C. et al. Application systems and insecticides to control Anticarsia gemmatalis in soybean. Rev. bras. eng. agríc. ambient. [online]. 2012, vol.16, n.8, pp.910-914. ISSN 1415-4366.

The application of insecticides to control Anticarsia gemmatalis in soybean is through hydraulic nozzles. Among the innovations stands out the air-assisted boom sprayer and the application of low oil volume by a rotary discs atomizer. In an experiment conducted with soybean during the 2009/2010 growing season, the control efficiency of A. gemmatalis using application systems and insecticides was assessed. The experimental design was a two-factor, with the factor A being the application systems, as follows: A1 - spraying with rotary discs atomizer; A2 - spraying with hydraulic nozzles and A3 - spraying with air-assistance; and factor D was composed of insecticides, as follows: D1 - Cypermethrin and D2 - Lufenuron + Profenofos. There was no interaction between insecticide and application systems and the insecticide Lufenuron + Profenofos presented a superior residual effect than Cypermethrin. The low oil volume spray system with rotary discs atomizer and system hydraulic nozzles with air-assisted boom sprayer are more efficient than hydraulic nozzles to control Anticarsia gemmatalis in soybean.

Keywords : chemical control; low oil volume; air assistance.
