1. Aphids (Greenfly and Blackfly): These small insects feed on the sap of plants, causing damage to leaves and buds. Aphids multiply rapidly and can attract ants due to the honeydew they produce.

2. Slugs and Snails: These mollusks are notorious for devouring tender plant shoots and leaves, particularly during damp weather. Their feeding activity can result in significant damage to young plants and seedlings.

3. Caterpillars: Various caterpillar species, such as cabbage white butterfly larvae and sawfly larvae, can feed on foliage, causing defoliation and weakening plants. Some caterpillars may also bore into fruits or stems.

4. Vine Weevils: The larvae of vine weevils feed on the roots of plants, leading to root damage and potential plant death.

5. Slender-bodied Beetle Larvae (Wireworms): Wireworms are the larvae of click beetles and can damage root crops such as potatoes, carrots, and onions by tunneling into tubers and roots.

6. Red Spider Mites: These tiny arachnids suck sap from the undersides of leaves, causing stippling and yellowing of foliage. They thrive in warm, dry conditions and can be particularly problematic in greenhouse environments.

Diseases:

1. Powdery Mildew: Powdery mildew is a fungal disease characterized by white powdery patches on leaves and stems. It can affect a wide range of plants, especially during warm, dry weather conditions.

2. Downy Mildew: Downy mildew is another fungal disease that manifests as yellow or brown patches on the undersides of leaves, often accompanied by a downy growth. It commonly affects crops such as lettuce, spinach, and brassicas.

3. Leaf Spots: Various fungi cause leaf spot diseases, resulting in dark, circular lesions on leaves. These diseases can weaken plants and reduce yield, particularly in wet and humid conditions.

4. Clubroot: Clubroot is a soil-borne disease that affects brassicas, causing swelling and distortion of roots, stunted growth, and yellowing of leaves. It can persist in the soil for several years, making crop rotation essential for management.

5. Botrytis (Gray Mold): Botrytis is a fungal disease that affects a wide range of plants, particularly in cool, damp conditions. It causes grayish-brown mold on affected plant parts, leading to rot and decay.

6. Apple Scab: Apple scab is a fungal disease that affects apple and pear trees, causing dark, scabby lesions on leaves and fruits. Severe infestations can result in reduced fruit quality and yield.
