ProAct™ Plant Health Regulator is the next-generation of foliar applied Harp-N-Tek™ protein products. It has been designed specifically to boost yield in field crops such as cotton, corn, soybeans, and rice. Similar yield increase responses with Harp-N-Tek foliar applications have been seen in sugar beets, dry edible beans, cucurbits, tomatoes, and other crops.
Dozens of widely respected independent consultants and agricultural scientists have worked with ProAct and documented the yield increases. Producers using ProAct also have seen how ProAct turns on a crop’s natural growth and defense capabilities. These innate systems work from the “inside out” to produce a healthier crop better able to handle stresses.
ProAct fits traditional crop management systems because it has a wide window of application and is a compatible tank mix partner with almost all post-emergence herbicides, fungicides, insecticides, plant growth regulators, and fertility amendments. Because ProAct strengthens plant health, tank mixing ProAct with other products that tend to induce plant stress has been a beneficial strategy.
Average yield increases with ProAct have included 69 pounds/acre in cotton, 7 bushels/acre in corn, 2.48 bushels/acre in soybeans, and 5.7 bushels/acre in rice. These yield increases provide a significant return on investment, typically 3-1 to 5-1 or more.
