    Symptom Identification and Management of Cotton Seedling Diseases
    Publication (PDF, 1.2MB)
    Authors: Jiahuai Hu, Randy Norton
    Seedling diseases, also known as damping-off (seedling death), are caused by several common soil-inhabiting fungi acting alone or collectively during pre-emergence and postemergence of cotton seedlings. Seedling diseases are common but often a minor problem in cotton production areas of Arizona in most years. However, significant stand loss to seedling diseases can occur sporadically in some fields without good crop rotation history.

    Weather Influences Desert Insect Pests
    Publication (PDF, 179KB)
    Authors: John C. Palumbo
    Local weather patterns can have a significant impact on the abundance of insect pests in vegetable crops, particularly in the southwestern U.S. where weather extremes are the norm. Components of weather, mainly temperature, moisture, and wind can either promote insect population growth or cause populations to decline. As we approach the normal cool, dry weather of winter, growers can expect insect activity to decrease. Why is that?
