How does abamectin work on suck pests?

Abamectin is effective against sucking pests primarily due to its mechanism of action which relies on the absorption of the chemical into the pest system. When applied to the foliage of plants, the active ingredient is taken up through the leaf surface, especially from the underside where many pests reside. This absorption process enables abamectin to disrupt the nervous system of targeted pests, leading to paralysis and eventually death.

The need for application from the underside of the leaf is particularly crucial because many sucking pests, such as aphids and spider mites, typically feed on the plant's sap from these hidden areas. Therefore, proper targeting in application ensures the active ingredient reaches the pests effectively.

While other approaches and factors like directly spraying on the pests or targeting their reproductive systems are important considerations in pest control, they do not capture the unique absorption mechanism that is essential for the effectiveness of abamectin against sucking pests. Similarly, while the ability to fly might influence pest mobility, it is not the primary action through which abamectin operates.
