Calm in corn: The corn borer retreats, though control must not cease

In the NOA, despite being an endemic area, the absence of the leafhopper reached 65% of the localities (compared to 54% in the previous survey), while in 21% the minimum level was recorded (1 to 4 adults per chromatic trap). An 11% of the traps were located in plots with early maize. The other endemic area, the NEA, is going through a period of stability, with 75% of the localities without the presence of the vector and 15% with captures at the minimum level. There have been variations in the intermediate categories, making monitoring more crucial ahead of the late plantings. 45% of the traps were located in plots with early maize, which is atypical in this region. In the Litoral, the absence of Dalbulus maidis reached 91% of the traps (compared to 75% in the previous report), while captures in the remaining 9% were at the lowest level, a highly relevant data considering that 95% of the traps were over maize crops. Similarly, in the Central-North region, the absence of the vector ...
