Complete Pest & Disease Management Guide

Common Pest Identification

White Bugs on Basil and Herbs

Most commonly aphids - small, soft-bodied insects that cluster on new growth. Look for sticky honeydew and yellowing leaves. Unlike whiteflies, aphids don't fly readily when disturbed.

Slug vs Caterpillar Damage

Slug damage: Irregular holes with ragged edges, silvery slime trails, damage overnight.
Caterpillar damage: Clean, round holes, dark droppings (frass), visible caterpillars during inspection.

Chewing vs Sucking Insects

Chewing insects (caterpillars, beetles) create holes and notches. Sucking insects (aphids, whiteflies) cause yellowing, wilting, and sticky honeydew without obvious holes.

Disease Recognition

Powdery Mildew on Zucchini

White, powdery coating on leaves, starting as small spots. Common on cucurbits (zucchini, squash, cucumbers) during humid conditions with poor air circulation.

Blight vs Other Leaf Spots

Blight creates dark spots with yellow halos that spread rapidly. Other fungal spots may be circular with defined borders. Blight is more aggressive and can kill plants quickly.

Root Rot Symptoms

Wilting despite moist soil is the key indicator. Check roots - healthy roots are white/tan and firm, while rotted roots are dark, mushy, and may smell foul.

Integrated Pest Management (IPM) Strategy

Cultural Controls

  • • Proper plant spacing for air circulation
  • • Crop rotation to break pest cycles
  • • Resistant varieties when available
  • • Proper watering techniques
  • • Sanitation and debris removal

Biological Controls

  • • Beneficial insects (ladybugs, lacewings)
  • • Companion planting
  • • Encouraging natural predators
  • • Beneficial microorganisms
  • • Trap crops to divert pests

Chemical Controls

  • • Organic options first (neem, soap)
  • • Targeted applications
  • • Rotate active ingredients
  • • Follow label instructions
  • • Consider beneficial impact
Seasonal Pest & Disease Calendar

Spring

  • • Aphid emergence
  • • Slug activity increases
  • • Root rot from wet soil
  • • Early fungal diseases

Summer

  • • Peak caterpillar activity
  • • Spider mites in hot weather
  • • Powdery mildew begins
  • • Bacterial diseases spread

Fall

  • • Late blight on tomatoes
  • • Increased slug damage
  • • Powdery mildew peak
  • • Aphid second generation

Winter

  • • Overwintering pest eggs
  • • Fungal spore survival
  • • Planning prevention
  • • Tool sterilization
Emergency Treatment Guide

Quick Diagnosis Checklist

  1. 1. Location: Where is the damage? (leaves, stems, roots, fruit)
  2. 2. Pattern: Random spots or systematic damage?
  3. 3. Timing: When did you first notice it?
  4. 4. Weather: Recent conditions (wet, dry, humid)?
  5. 5. Spread: Is it getting worse quickly?

First Aid Kit for Plants

Frequently Asked Questions

Q: How can I tell if white bugs on my basil are aphids or whiteflies?

Aphids are usually found in clusters and don't fly readily when disturbed. Whiteflies will fly up in a cloud when you touch the plant. Aphids also produce sticky honeydew, while whiteflies are more mobile.

Q: Is powdery mildew on zucchini dangerous to eat?

The fruit is generally safe to eat if you wash it thoroughly, but the disease weakens the plant and reduces production. Focus on treating the plant and preventing spread to other cucurbits.

Q: How do I know if it's slug damage or caterpillar damage?

Look for slime trails - slugs always leave silvery, shiny trails. Caterpillars leave dark droppings (frass) and create cleaner holes. Slug damage is typically more irregular and ragged.

Q: Can I prevent most pest problems organically?

Yes! Most pest problems can be prevented or managed with cultural controls (proper spacing, watering, crop rotation), beneficial insects, and organic treatments like neem oil and insecticidal soap.

Q: When should I remove an entire plant?

Remove plants with severe blight, advanced root rot, or heavy viral infections to prevent spread. If more than 50% of the plant is affected and treatment isn't working, removal is often the best option.
