When should sampling for the alfalfa pest begin?

Sampling for the alfalfa pest should ideally begin in mid-June because this timing aligns with the life cycles of many common pests that affect alfalfa. At this point in the growing season, plants are generally well-established, which allows for a more accurate assessment of pest populations. Additionally, many pests, such as alfalfa weevils and aphids, can reach significant levels by mid-June, so monitoring during this time is crucial for effective pest management strategies.

Starting pest sampling too early, such as in early spring, may not provide a complete view of the pest situation, as many pests may not yet be active or present in significant numbers. Similarly, sampling in late summer or fall may miss the critical early-season infestations that could require management interventions if detected earlier. Timing pest sampling correctly is vital for developing an efficient and effective integrated pest management plan for alfalfa crops.
