As temperatures rise across Ohio, soybean growers need to be especially mindful of herbicide applications during periods of heat stress. In this PCT Short, Jonah Johnson outlines key considerations to help minimize crop response and maximize application effectiveness.
Key topics covered include:
• Increased risk of crop stress when applying tank mixes containing surfactants and oils in hot conditions
• Understanding and anticipating temporary leaf speckling or crop response following applications
• Best practices for Liberty Ultra, including optimal performance under hot, sunny conditions
• Importance of proper carrier volume (15–20 gallons per acre) and AMS rates (1.5–3 pounds per acre)
• Meeting updated adjuvant requirements, including high surfactant oil usage and MSO rates
• Identifying soybean growth stages (R1–R2) and understanding how they impact herbicide label cutoffs
With reproductive stages approaching quickly, application timing and product selection are critical. Stay informed to protect crop health and maintain compliance with label requirements.
