Lack of agrochemicals puts soybean looper a threat in Southern Brazil
Feb. 18, 2015
Soybean growers in southern Brazil are facing difficulties to control the soybean looper because of the lack of efficient products against this pest. This assessment is made by Professor Jerson Carús Guedes from the Department of Crop Protection of the Federal University of Santa Maria.
"With the control of Helicoverpa armigera (corn earworm) relatively efficient, the soybean looper manifested itself strongly during January and continues to be difficult to control in February", explained by the expert.
"These difficulties are related to the small number of effective insecticides against this big caterpillars and elevated populations of this pest; and the late applications or inappropriate application times of the day (high temperature and low humidity) associated with the soybean development bring more difficulties to control it ", he highlighted.
The scholar explains that, besides this pest, with the reproductive period of soybeans "it is the moment to worry about bugs over soybeans, which are as harmful as earworms, and even more subtle, as they are less visible and its damages are not so perceptible at this moment. The bugs control should be done since the first bug is detected.”
