![]() Timing is key with any disease management plan and typically varies depending on the disease you want to control. It can help manage pre- and post-harvest fruit rots, spot the symptoms of pear blister mite and pear rust mite, as well as many other vegetable and tree fruit diseases. ![]() Regular and proper scouting techniques allow you to note significant changes and symptom development early enough to keep vegetable and tree fruit diseases at bay. There’s plenty of help available for seasoned and beginning vegetable farmers, whether you’re growing brassicas, potatoes, or any other fruit or vegetable crop. Fruit and Vegetable DiseasesĪs with all other types of crops, early identification is key for successful management and control of fruit and vegetable diseases. Soybean sudden death syndrome has pretty striking symptoms, but other diseases, such as brown stem rot or injury from chemicals can mimic it. Stem canker doesn’t show symptoms until well into the reproductive stages of growth. There are some late-season diseases to look out for in soybean crops. The quality and size of your yield depend on the severity of the disease. Small grains such as wheat may display symptoms of diseases such as head scab, black chaff, and Stagonospora glume. Recent developments have led to improved management practices, such as using disease resistance species. Yield-limiting plant diseases do not become problematic until the reproductive stages of development, which means there is little benefit to early season fungicide applications.įorage grasses are susceptible to a variety of leaf, stem, floral, and root diseases. Some common diseases to look for in corn include gray leaf spot and corn ear rot. To make the right decisions about the controls to use, you need to have first-hand knowledge of the condition of the crops or forages in the field. You can also turn to professional crop advisers or agronomy scouts for further guidance. There is plenty of information available for producers to increase their knowledge base, such as the Penn State Agronomy Guide. It’s also essential to have control procedures available. Successful disease control requires correct identification and knowledge of the cause and life cycle of the disease. Field Crop and Forage Plant DiseasesĪ wide variety of diseases attack field and agronomic crops and forages. Plant pathogens include fungi, fungal organisms, viruses, bacteria, phytoplasmas, viroids, parasitic higher plants, and nematodes.īeing able to quickly and accurately diagnose plant health gives you the best possible chance to solve any issues before losing the plant. These pathogens can spread from plant to plant and affect all parts of the plant, including roots, tubers, leaves, shoots, stems, crowns, fruit, and vascular tissue. These diseases are not infectious and include nutritional deficiencies, salt injury, ice, sun scorch, or soil compaction.īiotic diseases are caused by living organisms, otherwise known as plant pathogens. Plant disease is “anything that prevents the plant from performing to its maximum potential.” We classify plant diseases as either abiotic or non-infectious diseases and biotic or infectious diseases.Ībiotic diseases are those caused by external conditions rather than living agents. You’ll also find tips on integrated pest management and herbicide summaries. In this section, find information on plant disease identification and control, including rot, freeze damage, rust, blight, mold, scales, bacteria, viruses, fungus, wilt, mildew, gall, mites, moths, and cankers. However, cultural practices alone will not eliminate diseases from the garden.Preventing and controlling plant diseases is key to growing healthy plants. Heavy fertilization encourages the development of new growth that, if left unprotected, is fair game for fungal pathogens seeking a host. There is some logic to this theory as blackspot and powdery mildew tend to attack new plant growth first. Some hypothesize that excessive fertilization in early spring and late fall (when weather conditions support disease formation) can initiate the process. Planting young new roses at times when environmental conditions are ripe for disease development, without protecting those plants against attack, tends to invite the disease process. The gardener’s job is to balance plant selections so that management of fungal diseases in their roses can be attained within the maintenance parameters the gardener has available. There are many roses on the market that have exhibited tolerance to disease however, there is an even larger population of roses that are highly susceptible to fungal diseases.
