TWI Corn | TWI Soybean | TWI Winter Wheat
Utilizing advanced agronomy, historical yield and loss data, and weather history and forecasts, TWI Corn 2013 covers the major weather perils growers may face throughout the corn growing season:

Early Drought protects against post-planting drought that can limit early crop growth and threaten crop viability.
Drought protects against depleted soil moisture that can cause wilting, pollination issues and decreased yields.
Daytime Heat Stress protects against hot days that can reduce crop growth and result in ineffective pollination.
Nighttime Heat Stress protects against warm nights that result in diminished kernel growth due to increased plant respiration.
Excess Moisture protects against excessive local precipitation, which can lead to standing water that starves the crop of oxygen and promotes disease.
Low Heat Units/Freeze protects against a cool growing season or early freeze events that can prevent corn from reaching full maturity.
