1.Mechanism of Action
Nitenpyram is a novel neonicotinoid insecticide. It acts on acetylcholine receptors in the insect's nervous system, causing nerve signal transduction disorders. Insects exhibit persistent excitation and paralysis, ultimately dying due to nervous system dysfunction. It effectively controls various piercing-sucking pests such as aphids, planthoppers, whiteflies, leafhoppers, psyllids, and thrips. It is widely applicable to a variety of crops including rice, wheat, cotton, cucumber, eggplant, radish, tomato, potato, melon, watermelon, peach, apple, pear, citrus, grape, tea, and flowers, with a residual effect lasting approximately 20 days.
2. Product Features
(1) Rapid Action.Nitenpyram quickly knocks down piercing-sucking pests such as aphids, whiteflies, and thrips. After ingesting the sap containing nitenpyram, pests are poisoned within a short time, generally showing obvious symptoms within 1-2 hours, such as ceasing feeding, slow movement, and paralysis. It can quickly control pest population density and reduce pest damage to crops. Significant effects are visible within 24 hours after application.
(2) Strong Systemic Properties.Nitenpyram has excellent systemic properties. Once applied, it is rapidly absorbed by the roots, stems, and leaves of crops and quickly translocated to all parts of the plant. This allows the pesticide to reach the hidden feeding sites of pests. Even if pests are feeding on the underside of leaves or inside stems, they can still come into contact with the pesticide, resulting in a more comprehensive and effective insecticidal effect.
(3) Good compatibility.To improve control efficacy and delay the development of resistance, nitenpyram is often used in combination with other insecticides, such as pymetrozine (which enhances the speed and duration of action against planthoppers and aphids), bifenthrin (which broadens the insecticidal spectrum and also controls lepidopteran pests), buprofezin or abamectin (which improves overall control efficacy and controls resistant thrips or whiteflies), and flonicamid (which synergistically enhances efficacy and delays resistance development).
(4) High safety profile. At normal usage doses, nitenpyram is relatively safe for the environment and non-target organisms, has low toxicity to mammals and birds, is safe for crops, and has almost no phytotoxic effects on crops when used at high concentrations. It also has a short residual period, making it particularly suitable for use during the fruiting period.
