Correct answer: B

I is incorrect: Integrated pest management → Combining compatible prevention, monitoring and control methods. It avoids relying solely on routine pesticide applications. II is incorrect: Non-selective herbicide → Herbicide damaging a broad range of plants. Care is needed to avoid desirable vegetation.

Correct answer: C

Its management is essential to avoid becoming a pest source.

Correct answer: B

I is incorrect: Weed → Plant growing where it is unwanted. A useful species in one setting can be a weed in another. II is correct: Economic injury level → Pest density where damage cost equals control cost. It links pest abundance to economic loss.

Correct answer: A

Alternating effective modes of action can be one component.

Correct answer: C

I is correct: Quarantine → Measures limiting introduction or spread of regulated pests. Movement of planting material can spread pests. II is correct: Crop scouting → Systematic field observation for crop and pest conditions. Decisions improve when based on representative observations.

Correct answer: D

I is incorrect: Selective herbicide → Herbicide affecting some plant groups more than others. Selectivity depends on crop, weed, dose and application conditions. II is incorrect: Integrated pest management → Combining compatible prevention, monitoring and control methods. It avoids relying solely on routine pesticide applications.

Correct answer: C

It is normally set before the economic injury level is reached.

Correct answer: C

I is incorrect: Pesticide label directions → Product-specific instructions for authorised handling and use. They specify important restrictions and precautions. II is correct: Weed → Plant growing where it is unwanted. A useful species in one setting can be a weed in another.

Correct answer: B

Selectivity depends on crop, weed, dose and application conditions.

Correct answer: D

I is correct: Crop scouting → Systematic field observation for crop and pest conditions. Decisions improve when based on representative observations. II is incorrect: Pheromone trap → Trap using a chemical signal to attract target insects. It is often used for monitoring or specific control strategies.

Correct answer: C

Movement of planting material can spread pests.

Correct answer: B

I is correct: Crop scouting → Systematic field observation for crop and pest conditions. Decisions improve when based on representative observations. II is correct: Resistant variety → Plant variety less susceptible to a specified pest or disease. Resistance can reduce but need not eliminate damage.

Correct answer: B

A useful species in one setting can be a weed in another.

Correct answer: D

I is incorrect: Quarantine → Measures limiting introduction or spread of regulated pests. Movement of planting material can spread pests. II is incorrect: Weed → Plant growing where it is unwanted. A useful species in one setting can be a weed in another.

Correct answer: D

I is correct: Marketed surplus → Quantity actually sold in the market. It can differ from marketable surplus. II is incorrect: Participatory rural appraisal → Methods enabling communities to analyse local conditions. It uses local knowledge and collective assessment.

Correct answer: A

It can improve aggregation, services and bargaining power.

Correct answer: D

I is correct: Warehouse receipt → Document representing stored goods under a specified arrangement. It can support trade or finance subject to applicable rules. II is correct: Gross margin → Enterprise revenue minus variable costs. It does not deduct all fixed costs.

Correct answer: C

I is correct: Storage moisture control → Reducing conditions favourable to spoilage. Safe moisture requirements depend on the commodity. II is incorrect: Agricultural extension → Education and advisory support for farming decisions. It connects knowledge with local practice.

Correct answer: A

Cleaning, packaging and processing are possible routes.

Correct answer: D

I is correct: Farm budgeting → Estimating receipts and costs for planned activities. It supports comparison of production choices. II is correct: Demonstration plot → Field-based illustration of a practice or technology. Farmers can observe performance in relevant conditions.

Correct answer: B

It uses local knowledge and collective assessment.

Correct answer: A

I is correct: Marketed surplus → Quantity actually sold in the market. It can differ from marketable surplus. II is correct: Crop diversification → Adding or changing crops to broaden the production mix. It can spread market and production risk.

Correct answer: D

Safe moisture requirements depend on the commodity.

Correct answer: B

I is correct: Farmer producer organisation → Collective organisation of producers for economic activity. It can improve aggregation, services and bargaining power. II is correct: Warehouse receipt → Document representing stored goods under a specified arrangement. It can support trade or finance subject to applicable rules.

Correct answer: C

Farmers can observe performance in relevant conditions.
