Captan is labeled for ornamentals, lawns, vegetables, and fruit, sometimes alone or in mixes with other pesticides. The chemical and its uses are then described.Ĭaptan (Hi-Yield Captan Fungicide, Bonide Captan Fruit and Ornamental)-One of the best all-around, general-purpose fungicides to manage a huge variety of plant diseases, but it is not very good against powdery mildews and rusts. The following chemicals are listed first by their common name (in bold), then by trade names used for the home garden market (in parentheses).
#BONIDE INFUSE SKIN#
Some people can develop skin rashes if repeatedly exposed to some products. Many products can be toxic if accidently splashed into the eyes, inhaled, swallowed or absorbed through the skin. Some of the products below may be dangerous in their concentrated form to humans, domestic animals, and/or aquatic organisms such as fish.
Please read and follow the precautionary and safety statements on all pesticide labels including those listed as organic. Use fungicides as part of an integrated program for disease management. These products may help control diseases but are not a replacement for cultural practices such as crop rotation and the use of resistant varieties. None of these fungicides can cure heavily diseased plants. Although myclobutanil and tebuconazole are locally systemic, they must be applied soon after (or before) infection for maximum benefit. Captan, copper-based products, chlorothalonil, and sulfurs must be present before fungi begin the infection process. Many fungicides work by protecting healthy plant tissues. Understanding the disease cycle, proper timing, coverage and selection of the right fungicide are needed to get good control using fungicides. Liquid fungicide formulations usually already include such compounds. It is usually a good idea to add these materials to powders or dusts to be sprayed on plants. Some fungicides work better (stay on the plant longer or spread over the leaf surface) if a spreader sticker is mixed with the solution. You can use a product to control a disease that is not listed on the label as long as it is effective and the plant is on the label. Never use a product on a plant that is not listed on the label. Sometimes a rate range is given so use the higher rate when disease pressure is high and the lower rate when you expect disease pressure to be low. You can use less, but only if it is still effective at the lower rate. If the label says to use a certain amount of product, you cannot use more of it. However, there are some specific exceptions. No matter what anyone else says, always follow label directions. The ingredient list on the label will tell you what is in the product. Some products, such as a generic flower or fruit spray, may contain more than one type of chemical, usually an insecticide and a fungicide together.
The differences are in the formulation (such as a liquid or powder), in how much active ingredient there is per unit of weight (10%, 50%, etc.), or in how it is applied (as a spray or drench, for example). For example, chlorothalonil is packaged as Fung-onil, or Multi-Purpose Fungicide for the home market, and as Bravo or Exotherm Termil for commercial markets. Manufacturers and retailers use trade names. Plant pathologists usually refer to them by their general or common name such as chlorothalonil. Others, such as captan, tebuconazole, and chlorothalonil, are synthetically produced and not used for organic gardening.įungicide names can be very confusing at first. Some of the fungicides, such as the sulfur and copper-based products, can be used for growing organic produce. In the Host and Disease Descriptions section of this book, materials available in home garden formulations and packaging are identified with the symbol H. These products can still be used by home gardeners. Some of these labels, however, do not specify for home owners only or for residential use and therefore cannot be recommended by Washington master gardeners. Several companies cater to the home gardener by packaging in small quantities and selling through local variety stores or garden centers. Yet many of these fungicides are difficult for the average home gardener to obtain in small quantities. Most fungicides are not restricted in use or categorized as highly toxic. Many fungicides are registered for use on commercially produced plants, but only a few are readily available to home gardeners. Pscheidt, Extension Plant Pathology Specialist, OSU
