    1. Stunted growth from mealybugs.
    2. Spots on leaves caused by the rose black spot fungus.
    3. Decay caused by the rice blast fungus.
    4. Malformed stems or leaves caused by the ash dieback fungus.
    5. Discoloration caused by the tobacco mosaic virus.
    6. The presence of pests (aphids)

    • scab.

    What are the three types of plant diseases?

    Some plant diseases are classified as “abiotic,” or diseases that are non-infectious and include damage from air pollution, nutritional deficiencies or toxicities, and grow under less than optimal conditions. For now, we’ll look at diseases caused by the three main pathogenic microbes: fungus, bacteria and virus.

    What is the most common plant disease?

    Most Common Plant Diseases and Solutions

    1. Powdery Mildew. Most powdery mildew are very host specific, mildew on cucumbers will not infect roses.
    2. Black Spot. This is a common fungal disease of roses.
    3. Bacterial Canker or Blight.
    4. Shot Hole.
    5. Black Knot.
    6. Rust.
    7. Late Blight / Early Blight.
    8. Apple Scab.

    How do you control crop disease?

    Nine Keys to Plant Disease Prevention

    1. Understand the mechanism of infection.
    2. Choose the right plants for your site.
    3. Use disease-resistant varieties.
    4. Keep a clean garden: roguing, rotating crops, and sanitizing tools.
    5. Create a well-balanced soil.
    6. Keep plants healthy: proper watering, mulching, pruning, and fertilizing.

    What are the common disease of crops and their symptoms?

    Here Are 10 Common Plant Diseases In North America:

    • Blight. Blight is easily recognizable by the sudden death of all plant tissue including leaves, stems, and flowers.
    • Canker. Canker is identifiable by a dead area on the stem that is often discolored.
    • Gall.
    • Leaf Curl.
    • Leaf Spot.
    • Powdery Mildew.
    • Root Rot.
    • Wilt.

    What is disease cycle?

    A disease cycle is the chain of events involved in the development of a disease, including the stages of development of the pathogen and the effects of the disease on the host plants. All infectious disease-causing agents go through a disease cycle.

    What are the causes of crop diseases?

    A pathogenic organism, such as a virus, viroid, bacterium, fungus, mycoplasma, parasitic flowering plant, or nematode causes infectious plant diseases. An agent that is infectious can replicate inside or on a host plant and spread from one vulnerable host to the next.

    What is general control of crop plant disease?

    A variety of chemicals are available that have been designed to control plant diseases by inhibiting the growth of or by killing the disease-causing pathogens. Chemicals used to control bacteria (bactericides), fungi (fungicides), and nematodes (nematicides) may be applied to seeds, foliage, flowers, fruit, or soil.

    What causes crop disease?

    Infectious plant diseases are caused by living (biotic) agents, or pathogens. These pathogens can be spread from an infected plant or plant debris to a healthy plant. Microorganisms that cause plant diseases include nematodes, fungi, bacteria, and mycoplasmas.

    What are the two types of crop disease?

    Crop disease has traditionally been classified into two types: abiotic (also known as non-infectious) and biotic (infectious). Unfavorable environmental conditions frequently result in noncommunicable diseases.

    How to manage crop pests and disease?

    A guide to crop pest and disease management. Avoiding Pests and Disease – Some healthy plants have their internal pest and disease prevention tools. Plants will most attract diseases or pests when they are stressed by too much or too little water. Check soil moisture regularly to track the effectiveness of your watering strategy.

    What are root crop diseases and how to prevent them?

    Root crop diseases, which manifest as rotting, are a telltale sign of the presence of a virus. Some plants, however, may not show symptoms and may be latent carriers of disease. As a result, extreme vigilance is required in the fight against this type of infection.

    What diseases does crop rotation not control?

    Crop rotation does not control these all diseases because so many crops are susceptive. The common pests of foliage and flowering plants are spider mites, mealy bugs, fungus gnats, whitefly, and aphids.
