![]() ![]() Monocultures may therefore also lead to soil exhaustion when the soil becomes depleted of these nutrients.Ī couple of centuries ago, farmers produced multiple crops to feed their families and maybe put aside some surplus as a safeguard for the coming year. Growing the same crop year after year reduces the availability of certain nutrients and degrades the soil. Intensive use of agricultural chemicals also diminishes the amount of worms and insects available to birds as food. This means larger amounts of pesticides and herbicides, which can pollute rivers and streams, are needed compared to more diverse farming systems. Within the plant, Delaro Complete Fungicide is transported systemically throughout plant tissue for enhanced coverage.Raising a single crop has drawbacks as it increases the risk of disease and pest outbreaks because monocultures lack other plant and animal species that limit the spread of disease and control pests through predation. It then expands protection across the plant's exterior by moving via surface moisture, such as dew. Delaro Complete Fungicide diffuses in and on the waxy surface of the plant. These powerful ingredients work together to provide consistent control of most major corn and soybean diseases and increased plant health all season long. The third, trifloxystrobin, is a group 11, or strobilurin, that shows preventative activity on many diseases, and also offers benefits to plant health. The second, prothioconazole, is a group 3, or triazole, which has a very broad and deep spectrum of disease control and activity. The first, fluopyram, is a group 7, or SDHI, which has activity on important soybean diseases including white mold, brown spot and offers plant health benefits. ![]() What is Delaro ® Complete Fungicide and how does it work?ĭelaro Complete contains three active ingredients. For growers, a fungicide decision is a matter of considering production needs, risk management, timing of various agronomic practices and an eye to commodity prices. Also, timely fungicide applications, including foliar fungicides, help protect corn plants from fungal diseases throughout the season. Rainfall, followed by cool and then warm, humid weather, is conducive to development of this disease.Ī well-thought-out disease-management program, including best management practices, proper seed protection and selection, and fungicide applications using multiple modes of action should be implemented to sustainably manage corn diseases.Ī seed treatment provides great protection against early fungal diseases, especially in cool and damp spring conditions, and helps plant seedlings get off to a vigorous start. Rhizoctonia root rot can discolor and decay the outer layer of the main root and stem at the soil line and below. These early diseases can rot seed, reduce emergence, slow growth and stunt plants, thereby reducing yield. Several different soilborne or seedborne fungi in corn can cause seed and seedling rots, also called pre- and postemergence damping-off. Other significant stalk rots include Fusarium stalk rot, Gibberella stalk rot, Diplodia stalk rot, charcoal rot and bacterial stalk rot. The pith also becomes shredded, turning dark gray to brown. The stalk surface usually has a glossy shine. Black streaks and blotches, sometimes covering the entire stalk, appear on the surface of the lower stalk late in the season. ![]() The stalk rot phase of corn anthracnose is distinctive. Major diseases affecting the leaf include: Certain other pathogens must have a living host to overwinter, and spores must be carried on wind currents for new infections.įoliar diseases that establish prior to tasseling, or become severe within two to three weeks after tasseling and pollination, can result in significant yield loss. Fungal and bacterial inoculum can overwinter in crop residue on the soil surface and/or be spread by wind and water. Numerous corn diseases, including those caused by fungi and bacteria, exhibit symptoms in the leaves. Use our scouting guide to catch key diseases and consider using a fungicide with three modes of action, such as Delaro ® Complete fungicide. Knowing what these diseases look like is the first step in prevention and protection. Management for field corn, sweet corn and seed corn plant diseases is achieved through an integrated approach of best management practices and use of foliar fungicides and fungicide seed treatments. Managing these diseases early is essential to keeping your corn crop healthy and protecting your yields. Corn has to survive a number of disease threats throughout the season, such as gray leaf spot, northern corn leaf blight, tar spot and common and southern rust. ![]()
