Imidacloprid acts by contact and ingestion as an antagonist of the post-synaptic nicotinic receptors in the insect central nervous system, blocking acetylcholine at the post-synaptic membrane and impairing normal nerve function. The target pest's feeding activity ceases within minutes to hours and death usually occurs between 1-7 days depending on mode of application.
The compound has a systemic translaminar activity and is readily absorbed from the roots and distributed acropetally. This property is an important pre-requisite for soil applications such as in-furrow, granular, seed treatment and seedling-box applications in rice. Imidacloprid shows high selectivity, quick knock-down effect and long residual activity. It is effective against adult and larval stages of sucking and biting insects, soil insects and termites but has no effect on nematodes and spiders.
Since the first launch of imidacloprid, with consideration of new neonicotinoid insecticides entering the market, Bayer has issued guidelines to prevent the resistance and cross-resistance development based on baseline susceptibility and cross-resistance studies. Several studies have shown no cross-resistance with other insecticides but the monitoring of critical field populations worldwide is ongoing.
Trials in Bangladesh in 2000/1 (IPPC, 2004) on cotton showed that imidacloprid gave up to 70% control of aphids and jassids 75 days after sowing at an application rate of 4.5 g/kg seed. 3.5 and 2.5 g/kg seed gave around 60% and 65% control, respectively. Imidacloprid gave high levels of control of whitefly (Trialeurodes vaporariorum) in trials on greenhouse strawberries in California (IPPC, 2004).

Imidacloprid is highly toxic to honeybees by direct contact and harmful to insects in general, including predatory insects such as ladybirds and lacewings. Imidacloprid is slightly toxic to juvenile and adult fish and to aquatic invertebrates. The product appears to repel birds when used as a seed treatment.
Fate in soil:
Imidacloprid displays a medium absorption to soil and some degree of mobility, although leaching into deeper soil layers is not to be expected. In soil, imidacloprid is degraded continuously but not very rapidly; the product does not accumulate and is not persistent and the maximum concentrations in soil during long-term trials under unfavourable conditions reached a plateau level and declined in the absence of further applications. Imidacloprid has a half-life of 27 days in silt loam sediment under anaerobic conditions. Upon exposure to light, imidacloprid had a half-life of 39 days on sandy loam soil and the product is stable to hydrolysis at acid-neutral Ph under exclusion of light. The main routes of degradation of imidacloprid are photodegradation and microbial activity.
Fate in aquatic systems:
Imidacloprid degrades readily in the presence of light and the product rapidly undergoes degradation in water via photolytic reactions or microbial activity. Upon exposure to light, imidacloprid has a half-life of one hour in water.
Signal Word:CAUTION; Hazard Class:II(Moderately hazardous)
