How to Spot and Stop Plant Enemies: A Complete Guide

Types of Plant Diseases

Plant diseases are abnormal conditions that impair the normal functioning of plants. They can be caused by living organisms (biotic) or non-living factors (abiotic). In this part of the article, you will learn about some common types of plant diseases, their symptoms, causes, and treatments.

Biotic Plant Diseases

Biotic plant diseases are caused by living organisms that infect plant tissues and interfere with their metabolism or structure. These organisms can be fungi, bacteria, viruses, or nematodes. They can spread through various ways, such as wind, water, insects, animals, or contaminated tools. They can also be influenced by environmental factors, such as temperature, humidity, light, or soil pH.

Some common biotic plant diseases are:

• Fungal diseases: These are caused by fungi that produce spores that germinate on or in plant tissues and form hyphae (thread-like structures) that grow and feed on them. Some common fungal diseases are powdery mildew, leaf spot, blight, and rust. They usually cause spots, patches, or coatings on leaves, stems, flowers, or fruits. They can also cause wilting, rotting, or distortion of plant parts.
  • Powdery mildew: This is caused by various species of fungi that form white or gray powdery patches on leaves, stems, flowers, or fruits. It can affect many plants, such as roses, grapes, squash, cucumbers, and tomatoes. It can reduce photosynthesis, flowering, and fruiting of plants.

• Leaf spot: This is caused by various species of fungi that form circular or irregular spots on leaves or other plant parts. The spots can be brown, black, yellow, or red in color. They can also have a halo or a margin around them. It can affect many plants, such as beans, peas, lettuce, spinach, and strawberries. It can reduce photosynthesis and transpiration of plants.

• Blight: This is caused by various species of fungi that cause rapid and extensive browning or wilting of plant tissues. It can affect many plants, such as potatoes, tomatoes, onions, carrots, and celery. It can cause severe losses in yield and quality of plants.

• Rust: This is caused by various species of fungi that form orange, yellow, brown, or black pustules or streaks on leaves, stems, or fruits. It can affect many plants, such as wheat, barley, oats, corn, and roses. It can reduce photosynthesis, respiration, and translocation of plants.

• Bacterial diseases: These are caused by bacteria that enter plant tissues through natural openings (such as stomata or wounds) or vectors (such as insects or nematodes) and multiply rapidly inside them. Some common bacterial diseases are fire blight, bacterial wilt, bacterial canker, and bacterial leaf spot. They usually cause wilting, rotting, oozing, or cankering of plant parts.
  • Fire blight: This is caused by a bacterium called Erwinia amylovora that infects the flowers, shoots, and branches of plants in the rose family, such as apples, pears, quinces, and roses. It causes the infected parts to turn brown or black and look like they have been scorched by fire. It can also cause ooze to exude from the infected parts.

• Bacterial wilt: This is caused by various species of bacteria that infect the vascular system of plants and block the flow of water and nutrients. It can affect many plants, such as cucumbers, melons, squash, tomatoes, and eggplants. It causes the infected plants to wilt suddenly and irreversibly.

• Bacterial canker: This is caused by a bacterium called Clavibacter michiganensis subsp. michiganensis that infects the stems, leaves, and fruits of tomato plants. It causes the infected parts to develop dark brown lesions with yellow halos. It can also cause cracks or splits on the fruits.

• Bacterial leaf spot: This is caused by various species of bacteria that infect the leaves of plants and cause small water-soaked spots that enlarge and turn brown or black. It can affect many plants, such as peppers, lettuce, cabbage, and spinach. It can reduce photosynthesis and transpiration of plants.

Types of Plant Pests

Plant pests are living organisms that feed on or damage plant parts or products. They can be insects, mites, worms, rodents, birds, or mammals. In this part of the article, you will learn about some common types of plant pests, their symptoms, causes, and treatments.

Insect Pests

Insect pests are insects that chew, suck, bore, or gall plant tissues and interfere with their growth or reproduction. They can also transmit diseases or produce toxins that harm plants. They can spread through various ways, such as flight, crawling, hopping, or hitchhiking on other animals. They can also be influenced by environmental factors, such as temperature, humidity, light, or plant diversity.

Some common insect pests are:

• Aphids: These are small, soft-bodied insects that suck sap from plant tissues. Some common aphid species are green peach aphid, black bean aphid, cotton aphid, and rose aphid. They usually cause curling, yellowing, or distortion of leaves, stems, or flowers. They can also transmit viral diseases or produce honeydew that attracts ants or fungi.

• Spider mites: These are tiny arachnids that suck sap from plant cells. Some common spider mite species are two-spotted spider mite, red spider mite, and citrus red mite. They usually cause stippling, bronzing, or webbing on leaves or fruits. They can also cause defoliation or fruit drop of plants.

• Caterpillars: These are the larval stage of butterflies and moths that chew on plant tissues. Some common caterpillar species are cabbage worm, tomato hornworm, corn earworm, and armyworm. They usually cause holes, notches, or skeletonization on leaves, stems, flowers, or fruits. They can also cause webbing, frass (droppings), or silk on plant surfaces.

• Thrips: These are tiny insects that pierce and suck sap from plant cells. Some common thrip species are western flower thrip, onion thrip, and melon thrip. They usually cause silvering, streaking, or scarring on leaves, flowers, or fruits. They can also transmit viral diseases or cause deformities or drop of plant parts.

• Whiteflies: These are small, white-winged insects that suck sap from plant tissues. Some common whitefly species are greenhouse whitefly, sweet potato whitefly, and silverleaf whitefly. They usually cause yellowing, curling, or wilting of leaves. They can also produce honeydew that attracts ants or fungi or transmit viral diseases.

Non-Insect Pests

Non-insect pests are living organisms other than insects that feed on or damage plant parts or products. They can be mites, worms, rodents, birds, or mammals. They can spread through various ways, such as digging, burrowing, gnawing, pecking, or grazing. They can also be influenced by environmental factors, such as food availability, population density, or predation pressure.

Some common non-insect pests are:

• Nematodes: These are microscopic worms that live in soil or water and feed on plant roots. Some common nematode species are root-knot nematode, cyst nematode, sting nematode, and lesion nematode. They usually cause galls, knots, or lesions on roots, as well as reduced growth, yield, or quality of plants. They can also facilitate the entry of other pathogens or pests.

• Slugs and snails: These are mollusks that have soft bodies and produce slime trails. They feed on plant tissues by rasping them with their radula (a tongue-like organ with teeth). They can affect many plants, such as lettuce, cabbage, strawberry, and hosta. They usually cause irregular holes or notches on leaves, stems, flowers, or fruits. They can also cause slime trails or droppings on plant surfaces.

• Moles: These are mammals that have cylindrical bodies and powerful forelimbs for digging. They feed on earthworms and other soil organisms by tunneling through the soil. They can affect many plants, such as lawn grasses, bulbs, tubers, and roots. They usually cause raised ridges or mounds of soil on the ground. They can also cause damage to roots or underground parts of plants.

• Birds: These are vertebrates that have feathers and wings. They feed on plant parts or products by pecking, plucking, or tearing them. They can affect many plants, such as corn, sunflower, berry, and grape. They usually cause holes, punctures, or tears on leaves, stems, flowers, or fruits. They can also cause noise, droppings, or nests on plant surfaces.

For example, fungicides, bactericides, insecticides, miticides, nematicides, or molluscicides. These methods are usually fast and effective, but they can also have negative effects on beneficial organisms, human health, or the environment. They can also cause resistance or residues if used improperly or excessively.
  • Biological methods: These are methods that use living organisms or their products to control or suppress diseases or pests. For example, natural enemies (such as predators, parasites, or pathogens), biopesticides (such as Bacillus thuringiensis or neem oil), or biostimulants (such as compost tea or seaweed extract). These methods are usually safe and eco-friendly, but they can also have variable results depending on environmental conditions, compatibility, or availability.
  • Cultural methods: These are methods that use physical or mechanical means to prevent or reduce diseases or pests. For example, washing off, pruning off, handpicking, trapping, repelling, deterring, or using barriers. These methods are usually simple and inexpensive, but they can also be labor-intensive or time-consuming.
• Apply the treatment at the right time, dosage, and frequency: You should apply the treatment when the disease or pest is most vulnerable and when the plant is least stressed. You should also apply the treatment at the recommended dosage and frequency according to the label instructions and safety precautions. You should avoid underdosing or overdosing that may reduce effectiveness or increase toxicity.
• Monitor the results and adjust the treatment if needed: You should monitor the results of the treatment by observing the symptoms, signs, and patterns of the disease or pest. You should also measure the impact of the treatment on the plant growth, yield, or quality. You should adjust the treatment if needed by changing the method, timing, dosage, or frequency. You should also consider integrating different methods to achieve better control or suppression.
• Dispose of the waste properly according to the regulations: You should dispose of the waste generated by the treatment properly according to the regulations. For example, you should dispose of empty containers, unused products, or infected parts in a sealed bag or bin. You should also clean and sterilize your tools, equipment, or clothing after use. You should avoid contaminating the soil, water, air, or other plants or animals with your waste.

Specific Examples on How to Treat Plant Diseases and Pests

General Strategies on How to Prevent Plant Diseases and Pests

To prevent plant diseases and pests, you should follow these strategies:

• Select resistant varieties: You should select varieties of plants that are resistant or tolerant to common diseases or pests in your area. You can find out the resistance or tolerance level of different varieties by checking the labels, catalogs, or websites of seed or plant suppliers. You can also consult your local extension office or plant clinic for recommendations. You should avoid planting susceptible varieties that are prone to diseases or pests.
• Maintain good hygiene: You should maintain good hygiene by removing weeds, debris, and infected plants that may harbor or spread diseases or pests. You should also sanitize tools or equipment that may be contaminated by diseases or pests. You should use bleach, alcohol, or heat to disinfect tools or equipment before and after use. You should also wash your hands and clothes after handling diseased or infested plants.
• Practice crop rotation: You should practice crop rotation by changing the location or type of plants every season or year to avoid the buildup of pathogens or pests in the soil. You should avoid planting the same crop or related crops in the same spot for more than two years. You should also avoid planting crops that share the same diseases or pests in the same area. You should plant crops that have different growth habits, nutrient requirements, or pest resistance.
• Use mulches: You should use mulches such as straw, bark, or compost to cover the soil and suppress weeds, retain moisture, and improve fertility. Mulches can also prevent soil erosion, reduce soil compaction, moderate soil temperature, and enhance soil biodiversity. Mulches can also create a physical barrier between the soil and the plant parts, reducing the contact or splash of pathogens or pests.
• Create diversity: You should create diversity by planting different species or varieties of plants that can attract beneficial insects, repel pests, or enhance each other’s growth. You can use techniques such as intercropping, companion planting, polyculture, or permaculture to create diversity. Diversity can also increase the aesthetic appeal, nutritional value, and ecological stability of your garden.

  • Example response: Hello, this is Bing. It sounds like you want to grow tomatoes in containers on your balcony. That’s a great idea! Tomatoes are one of the most popular and rewarding crops to grow in containers. You can enjoy fresh and tasty tomatoes from your own balcony with some simple steps. Here are some tips on how to grow tomatoes in containers:
  • Choose the right variety: You should choose a variety of tomato that is suitable for container growing. Some varieties are specially bred or adapted for containers, such as ‘Patio’, ‘Balcony’, or ‘Tiny Tim’. These varieties are compact, dwarf, or determinate, which means they have a limited growth habit and produce fruits over a short period of time. They also have fewer problems with diseases or pests.
  • Choose the right container: You should choose a container that is large enough to accommodate the root system and the foliage of the tomato plant. The container should have a capacity of at least 5 gallons (19 liters) for one plant, or 10 gallons (38 liters) for two plants. The container should also have drainage holes at the bottom to prevent waterlogging or root rot.
  • Choose the right soil: You should choose a soil mix that is rich in organic matter, well-drained, and slightly acidic. You can use a commercial potting mix that is designed for vegetables, or make your own mix by combining equal parts of peat moss, perlite, and compost. You can also add some fertilizer to the soil mix, such as a slow-release granular fertilizer or an organic fertilizer such as fish emulsion or seaweed extract.
  • Choose the right location: You should choose a location that is sunny, warm, and sheltered. Tomatoes need at least 6 to 8 hours of direct sunlight per day to produce fruits. They also prefer temperatures between 65°F (18°C) and 85°F (29°C) to grow and ripen. They also need protection from strong winds, heavy rains, or frost that can damage their stems, leaves, or fruits.
  • Choose the right care: You should care for your tomato plants by watering, fertilizing, pruning, staking, and harvesting them regularly. You should water your plants deeply and evenly, but not too frequently or excessively. You should check the soil moisture by inserting your finger into the soil up to the second knuckle. If it feels dry, you should water your plants until water drains out of the bottom of the container. You should fertilize your plants every two weeks with a balanced liquid fertilizer that is diluted to half strength. You should prune your plants by removing any suckers (side shoots) that grow between the main stem and the branches. This will allow more air and light to reach the plant and prevent diseases or pests. You should stake your plants by inserting a wooden or metal stake into the soil next to the plant and tying the stem loosely to the stake with a soft string or cloth. This will support the plant and prevent it from falling over or breaking under the weight of the fruits. You should harvest your fruits when they are fully ripe and have a uniform color. You can gently twist or cut them off the stem with a sharp knife or scissors.

By following these tips, you can grow tomatoes in containers on your balcony successfully and easily. You can enjoy fresh and delicious tomatoes from your own balcony throughout the season. Happy gardening!
