APPLICATION TIMING AND CROP STAGING:

Bertha Armyworm: Apply when the insects are at a vulnerable stage (early larval instars). Consult provincial guidelines for treatment threshold and advice.

Diamondback Moth Larvae: Apply when the insects are at a vulnerable stage (early larval instars). Consult provincial guidelines for treatment threshold and advice.

Flea Beetles: Begin scouting for feeding damage within a week of emergence. Apply to crop at first signs of feeding. SILENCER® 120 EC can also be used to spray a 15 m strip around the field edge to reduce insect migration.

Grasshoppers: Apply the low rate (26 ml/ac) up to the 3rd nymphal stage (1 cm long), or when insect numbers are low. Apply the high rate (34 ml/ac) when grasshoppers are larger, up to but not including winged adults (up to 2.5 cm in length) or when insect numbers are high.

Potato Insects (except Colorado Potato Beetle): Apply when insects or feeding damage appears.

Timing of applications should be based on the presence of vulnerable pest developmental stages and significant populations as determined by local monitoring. Consult the label for complete crop list and insect timing.
