Broadcast Equipment Spike ® 20P herbicide pellets may be applied with airplane or helicopter equipment with a positive metering device. You may also apply it with a Solo backpack blower that can cover swaths up to 70 feet. For more details, talk with your Corteva Agriscience representative. You may also use Spike 20P to control individual trees or scattered stands of brush as well. How Spike 20P Works • Pellets adhere to soil and won’t break down under sunlight and heat before water activates them. • Spike 20P is then absorbed by the brush root system and moved up to leaves. • By inhibiting photosynthesis, Spike 20P causes brush to defoliate slowly, turn brown and die, encouraging grasses to grow. • Brush may refoliate and defoliate for up to two years, gradually depleting its food reserves. • Brush is completely dead, roots and all. 16
