 I'm Darren Hefty with Hefty Naturals. When your crops experience stress, you lose yield at harvest, and your crops are most vulnerable to heat and drought during the critical reproductive stages. Shield your crops from the worst summer can bring with a foliar application of heat shield. Fields treated with heat shield exhibit crop canopies up to 10 degrees cooler than untreated, and 2023 trials showed a 14 bushel increase in corn. Reduce stresses and shield your yield with heat shield from Hefty Naturals.
