Optimizing Aphid Control: The Efficacy of Nitenpyram

Dec 22, 2023

Aphids are the most common pests on garden plants. They are widely distributed, reproduce quickly, are large in number, and cause damage for a long time.

A suitable climate allows them to reproduce for one generation in 4-5 days, and they can reproduce for dozens of generations a year, repeating themselves over and over again, causing huge long-term harm. For example, green peach aphid, Liu’an aphid, long tube aphids, pine aphid, etc. are common in gardens.

Nitenpyram is a nicotinamide insecticide developed by Takeda in 1989. It has super high efficiency, broad-spectrum, small dosage, low toxicity (at the level of slightly toxic preparations), long efficacy, harmless to crops, and safety. advantage.

Its effect in killing aphids is more than 10 times that of other drugs. It is a new variety that has replaced highly toxic organophosphorus pesticides in recent years.

The Harm of Aphids to Plants

Aphids are important vectors for virus transmission. When they pierce and suck, they carry a variety of viruses and spread them to plants, inducing viral diseases and causing plant deformity and development; the leaves shrink irregularly, curl, fall off, deform, change color, and even the whole plant dies.

Aphids continuously secrete and discharge honeydew, which is transparent and sticky and drips onto leaves and roads. It not only hinders the photosynthesis of leaves, but also provides a good culture medium for bacteria, which can easily induce coal pollution. There is a lot of honeydew dripping under the tree, which affects the landscape effect.

There are a large number of aphids. They often gather in plant leaves, tender stems, flower buds, terminal buds and other parts to suck sap, which hinders plant growth, causing leaves to shrink, curl, and become deformed, and new leaves to be slightly damaged. Affected by aphids, growth retardation, galls, and tree weakness often occur.

How does Nitenpyram work

How does Nitenpyram work?

Nitenpyram mainly acts on the nervous system of insects. It has a nerve-blocking effect on the synaptic receptors of pests, expands the position of the diaphragm after spontaneous discharge, and ultimately reduces synaptic diaphragm stimulation, causing the axonal synaptic diaphragm potential channel stimulation to disappear, leading to paralysis and death of the pest.

Nitenpyram has excellent systemic and penetrating effects, broad insecticidal spectrum, is safe and non-toxic, and is an updated product for the prevention and control of whiteflies, aphids, pear psyllids, leafhoppers, thrips and other sucking mouthpart pests.

What is the advantage of Nitenpyram?

Nitenpyram is a neonicotinoid insecticide that has several advantages in agricultural pest control, particularly in the control of sucking insects such as aphids.

Here are some of the main benefits of nitenpyram:

Take effect quickly. Nitenpyram mainly acts on the nervous system of insects. It has a nerve-blocking effect on the synaptic receptors of pests, expands the diaphragm position after spontaneous discharge, and finally reduces the synaptic diaphragm stimulation, resulting in the disappearance of the axonal synaptic diaphragm potential channel stimulation, resulting in paralysis and death of pests.

The insecticidal spectrum is wide. Mainly used to control stinging insects, such as aphids, rice plantoppers, whitefly tabaci, white whitefly, pear psyllid, leafhoppers, thrips and other pests.

Safe and efficient. Nitenpyram is very safe for crops, especially for hanging fruit trees, and the residual period is relatively short.

P Nitenpyram has internal absorption conductivity, very strong permeability, after application, can conduct quickly, and directly hit pests.

Suitable for a wide range of crops. Field crop fields, cash crop fields, orchards, tea gardens and other crops can be used.
