4. Bacterial Canker

Bacterial canker is a serious disease affecting many fruit trees, particularly citrus. It causes lesions on leaves, stems, and fruit.

Symptoms: Raised, corky lesions on fruits, leaves, and twigs
Control: Copper-based sprays, pruning infected parts, quarantine measures

5. Tomato Wilt Diseases

Several pathogens can cause wilt in tomatoes, including Fusarium and Verticillium. These diseases block the plant’s vascular system, leading to wilting and eventual death.

Symptoms: Wilting, yellowing leaves, brown discoloration in stem cross-sections
Control: Resistant varieties, crop rotation, soil solarization

Common Crop Pests

Now, let’s turn our attention to some of the most problematic pests that farmers encounter:

1. Aphids

Aphids are small, soft-bodied insects that feed on plant sap. They can reproduce rapidly and often transmit plant viruses.

Symptoms: Curled or distorted leaves, sticky honeydew on leaves
Control: Insecticidal soaps, natural predators, neem oil

2. Scale Insects

Scale insects, including armored scales, are small, immobile pests that attach themselves to plant parts and feed on sap.

Symptoms: Small, bumpy scales on stems and leaves, yellowing leaves
Control: Horticultural oils, pruning affected parts, biological control

3. Mites

Mites, such as spider mites and the olive mite (Aceria oleae), are tiny arachnids that can cause significant damage to crops.

Symptoms: Stippling on leaves, webbing (for spider mites), leaf bronzing
Control: Miticides, predatory mites, increasing humidity

4. Fruit Flies

Fruit flies are a major pest for many fruit crops, laying eggs in ripening fruit and causing significant economic losses.

Symptoms: Small punctures on fruit, premature fruit drop
Control: Traps, bait sprays, sanitation practices

5. Lace Bugs

Lace bugs are small insects that feed on the undersides of leaves, causing stippling and discoloration.

Symptoms: Yellow or white stippling on upper leaf surfaces
Control: Insecticidal soaps, neem oil, proper plant care
