Imidacloprid can be found in the trunk, the branches, the twigs, the leaves, the leaflets, and the seeds. Many trees are wind pollinated. But others such as fruit trees, linden, catalpa, and black locust trees are bee and wind pollinated and imidacloprid would likely be found in the flowers in small quantities.

Imidacloprid can be added to the water used to irrigate plants. Controlled-release formulations of imidacloprid take 2–10 days to release 50% of imidacloprid in water. [36] It is applied against soil pests, seed, timber, and animal pests as well as foliar treatments.

Although imidacloprid is a good insecticide for the control of pests who have piercing-sucking mouthparts, frequent reuse may lead to the severe resistance of pests. [24] The application of plant secondary substances also plays a pivotal role in population control since people are increasingly putting a premium on environmental protection and ...
Insects feed from various compartments in the plant. Most of the major pests are either chewing insects or sucking insects. [13] Chewing insects, such as caterpillars, eat whole pieces of leaf. Sucking insects use feeding tubes to feed from phloem (e.g. aphids, leafhoppers, scales and whiteflies), or to suck cell contents (e.g. thrips and mites).
Trunk injection or endotherapy also known as vegetative endotherapy, [1] [2] [3] is a method of target-precise application of pesticides, [4] [5] [6] plant resistance activators, [7] or fertilizers [8] into the xylem vascular tissue of a tree with the purpose of protecting the tree from pests, or to inject nutrients to correct for nutrient deficiencies.
The most common insecticide is imidacloprid, which can be effective for several years if absorbed through the soil. [16] Tree roots absorb and transport the product into the foliage and kill hemlock woolly adelgid. Soil drenches must be applied when soil moisture is adequate for the tree roots to absorb the product.
