Corn borers are a significant pest affecting maize crops, causing considerable damage if not properly managed. Effective control methods include the use of various pesticides, which differ based on the pest’s life cycle and the stage of crop growth. Below, we outline the types of pesticides used for corn borer control and their application methods.
Corn Borer Control Pesticide :
- Emamectin Benzoate and Beta-cypermethrin:
- Usage: Suitable for early prevention or when pests first appear. This combination works well with herbicides.
- Dosage: Apply 50g per mu (approximately 0.067 hectares) of a 3.2% Emamectin Benzoate and Beta-cypermethrin mixture.
- Emamectin Benzoate and Lufenuron:
- Usage: Effective in killing eggs with a longer residual effect.
- Dosage: Use 20ml per mu of a 3% Emamectin Benzoate and Lufenuron solution.
- Emamectin Benzoate and Chlorfenapyr:
- Usage: Suitable for peak pest periods, showing noticeable effects within 1-2 hours of application. However, it is more costly.
- Dosage: Spray 30ml per mu of a 12% Emamectin Benzoate and Spinetoram suspension.
- Emamectin Benzoate and Indoxacarb:
- Usage: Best used during the trumpet stage or early tasseling stage of corn. Effective against resistant corn borers with a long residual effect.
- Dosage: Apply 15ml per mu of a 10% Emamectin Benzoate and Indoxacarb spray.
- Chlorantraniliprole:
- Usage: Most effective during the seedling stage, controlling corn borers and other pests.
- Dosage: Use 20ml per mu of a 5% Chlorantraniliprole suspension.
Optimal Application Timing:
- Seedling Stage:
- Timing: Early spring, when corn is in the heart leaf stage (before the large trumpet stage). This is the peak period for the first generation of pests, and early prevention is crucial.
- Corn Tasseling Stage:
- Timing: When larvae begin to move into the corn ears. Applying pesticides at this stage is essential to prevent significant damage.
Usage Precautions:
- Spraying Time: The best times for application are early morning or late afternoon, as corn borer moths are most active during these periods.
- Timeliness: Apply pesticides immediately upon detecting pests to prevent them from entering the corn ears and causing more extensive damage.
