I need to apply it how long before a rain to be effective? How soon after application does it need to rain to be effective? Is it ap 90 oz per acre?
Pre-Emergents like Pendulum 3.3 EC should be applied before the weeds start to germinate. We suggest that you contact you local Extension Office to get the best time for your area. The efficacy of this product will improve if followed by 1 1/2" of rainfall or its equivalent in sprinkler irrigation. If it is not activated by rainfall or irrigation within 30 days, erratic weed control may result. You apply it at 1.3 - 1.8 oz per 1000 sq ft or 3.6 to 4.8 pts per acre.
