Recognize the problem

The armyworm caterpillar opens holes in the inner leaves of corn. In some cases, their waste can be seen on the leaves. when the plant is large, the armyworm is located in the cob, entering by the ear silk and causing damage to the grains which can lead to rot.

Background

During the night, gray moths or butterflies can be seen. The moths lay eggs, from which the armyworm is conceived.

If we always apply the same type of insecticide, the armyworm becomes resistant and the insecticide will no longer kill it.

always apply a similar kind of bug spray, the armyworm becomes safe and the insecticide will at this point don’t kill it.

Management

Before spraying insecticides, confirm if there are a large number of armyworms in the field.

For control, application of insecticides like Avtar. The application should be done when plants show 3-6 leaves.

In one cycle, you can spray Avtar; in the following one, you need to change to chlorpyriphos, so you don’t utilize consistently similar insecticide in continuous cycles.

Take care when using these chemicals because they are broad-spectrum insecticides and are therefore also harmful to natural enemies.

When utilizing an insecticide, consistently wear protective clothing and follow the instructions on the item label, such as dosage, the timing of application, and pre-harvest interval.
