The chemical component responsible for pest control action.

What does the Re-entry Period indicate?

The time required before entering a treated area safely without protective equipment.

What does a 'Signal Word' on a pesticide label indicate?

The pesticide toxicity level and hazard.

What is Mechanical Control in pest management?

Pest management using physical devices or manual techniques.

What is the purpose of a Light Trap?

To attract nocturnal insects for monitoring.

What is a Sticky Trap used for?

To capture flying insects using adhesive surfaces.

What is a Pheromone Trap?

A trap using chemical attractants to lure insects.

What is the importance of reading pesticide labels?

Ensures effective pest control, prevents misuse, protects health, and reduces contamination.

What is the purpose of a yellow sticky trap?

To attract aphids and whiteflies.

When should sticky traps be replaced?

When surfaces become fully covered.

What is the function of a pheromone trap?

To lure specific insect pests using chemical attractants.

What should be included on the label of a pheromone trap?

Group number, section code, and methyl eugenol.

What data should be recorded for a light trap?

Insect name, family, order, and number collected.

What are the advantages of mechanical pest control?

Low-cost, environmentally friendly, reduces pesticide dependence, and easy to fabricate.

Name three common insects collected by a light trap.

Moths, beetles, and flies.

What is a pest?

Any organism causing damage to crops, humans, or the environment.

What is a plant pathogen?

A disease-causing organism such as fungi, bacteria, or viruses.

What is the role of natural enemies in pest management?

To suppress pest populations, such as predators and parasitoids.

What is foliar damage?

Injury occurring on plant leaves.

What are the common symptoms of pest damage on vegetable crops?

Holes on leaves, yellowing leaves, leaf curling, wilting, spots and blights, stunted growth.

What is the importance of pest monitoring?

Detects pest outbreaks early, prevents severe crop damage, and supports sustainable agriculture.

What is a weed?

A plant growing where it is not desired.

What is the purpose of quadrat sampling?

To observe and count weeds within a fixed sampling area.

What is population density in the context of weed assessment?

The number of individuals per unit area.

What are the characteristics of broadleaf weeds?

Wide leaves with net veins.

What is the significance of weed composition analysis?

Helps improve weed management strategies.

What are the common categories of weeds?

Grasses, sedges, and broadleaf weeds.

What is the function of lady beetles in pest management?

They feed on aphids.

What does 'canopy cover' refer to?

The area of ground covered by plant foliage.

What is the likely pest if leaves have ragged edges?

Caterpillar.

What does 'basal cover' measure?

The ground area occupied by the base of plants.

What is the purpose of using a point transect method?

To estimate vegetation cover along a sampling line.

What is the role of spiders in pest management?

They are predators of various insects.

What is the objective of monitoring weeds in agroecosystems?

To identify dominant weed species and evaluate weed-crop competition.

What should be documented during pest observation?

Crop observed, pest identified, symptoms observed, and presence of natural enemies.

What is the likely cause of yellowing leaves in plants?

Nutrient deficiency or disease.
