Imidacloprid powder is a nitromethylene insecticide, belonging to the chlorinated nicotinoid insecticides, also known as neonicotinoid insecticides. Its chemical formula is C9H10ClN5O2, and it has the characteristics of broad-spectrum, high efficiency, low toxicity, and low residue. Pests are not easily resistant to them and have multiple effects such as contact killing, gastric toxicity, and internalization. After pests come into contact with pesticides, the normal conduction of the central nervous system is obstructed, resulting in paralysis and death.
Function characteristics
Efficient insecticidal: Imidacloprid has significant control effects on various pests, quickly reducing the number of pests and protecting crops. The product has good quick acting effect, with a high preventive effect within one day after medication, and a residual period of about 25 days. The efficacy of drugs is positively correlated with temperature, and when the temperature is high, the insecticidal effect is better.
Broad spectrum: Imidacloprid can control pests on various crops and has a wide range of applications. It is not only effective against piercing sucking mouthparts pests such as aphids, planthoppers, whiteflies, leafhoppers, thrips, etc., but also has a certain effect on Coleoptera, Diptera, and Lepidoptera pests such as leaf miner, rice weevil, and leaf miner. However, it is ineffective against nematodes and red spider mites.
Low toxicity: Imidacloprid has relatively low toxicity to mammals and poses minimal harm to humans and the environment when used. Therefore, it is widely used in agricultural production.
Intrinsic absorption: Imidacloprid has systemic absorption and can be absorbed by plants to conduct electricity within the plant, thereby also acting against pests hidden inside the plant. This characteristic makes imidacloprid more efficient in controlling pests.
Long lasting effect: A single application of imidacloprid can continuously exert its insecticidal effect for a longer period of time, reducing the frequency and cost of application. This is an important advantage for agricultural producers as it can reduce their operating costs.
Good stability: Imidacloprid can maintain good chemical stability and efficacy under different environmental conditions. This enables it to perform well under various climatic and soil conditions.
High cost-effectiveness: Imidacloprid is relatively affordable and has a high cost-effectiveness in agricultural production. This makes it the preferred insecticide for many agricultural producers.
Easy to use: Imidacloprid comes in a variety of formulations, including wettable powders, suspensions, emulsions, etc., making it easy to choose and operate according to different needs and usage scenarios.
Prevention and control targets
Imidacloprid powder is mainly used to control pests on various crops. The following are its main control targets and methods:
(1) Rice:
Control targets: Aphids, planthoppers, leafhoppers, thrips and other piercing sucking mouthparts pests, as well as rice weevils, rice mud bugs and other Coleoptera pests.
Medication time and frequency: Spray the pesticide from the early stage of pest occurrence or when the pest population starts to increase rapidly. Spray once every 15 days or so, and spray twice in a row.
Precautions: Avoid spray in strong sunlight to avoid reducing the efficacy. Also, do not mix with alkaline pesticides.
(2) Control targets:
Aphids, leafhoppers, thrips and other piercing sucking mouthparts pests.
Medication time and frequency: Spray from the early stage of pest occurrence, spraying once every 15 days or so, and spraying twice in a row.
Attention: When taking medication, pay attention to protection to prevent contact with the skin and inhalation of powder and liquid medicine. After medication, the exposed area should be promptly washed with clean water.
(3) Cotton:
Control targets: Aphids, planthoppers, whiteflies, leafhoppers and other piercing sucking mouthparts pests, as well as Coleoptera pests such as leafhoppers and rice weevils.
Dosage and usage: 11.2518.75 g imidacloprid per hectare for spray. Pay attention to the uniformity of spray, and repeat the application for 12 times depending on the occurrence of pests.
Precautions: It is not suitable to use spray under strong sunlight and low temperature to avoid reducing the efficacy. Do not apply pesticides on windy days or when it is expected to rain within an hour.
(4) Corn:
Target of prevention and control: Aphids, planthoppers and other piercing sucking mouthparts pests.
Application method and times: spray or seed dressing can be used for prevention and control. During spray, spraying starts from the initial stage of pests, once every 15 days or so, and twice in a row. When mixing seeds, mix imidacloprid with the seeds and sow.
(5) Potatoes:
Target of prevention and control: Aphids, leafhoppers and other piercing sucking mouthparts pests.
Medication method and times: spray or soil treatment can be used for prevention and control. During spray, spraying starts from the initial stage of pests, once every 15 days or so, and twice in a row. During soil treatment, imidacloprid is mixed with soil and applied to crop roots.
During the process of growing flowers, insect problems may often trouble you. These small organisms may cause serious damage to your plants and even lead to their death. At this point, imidacloprid can play its important role. Imidacloprid is an effective insecticide with targeted effects on flowers and insects.
Mechanism of action
Imidacloprid powder is a new type of nitromethylene insecticide, characterized by high efficiency, low toxicity, and low residue. It can act on the nervous system of insects, interfere with their transmission mechanisms, and cause insect death. Imidacloprid has minimal damage to plants and does not have a significant impact on plant growth when used.
Usage method
1. Correct use according to the instructions:
When using, strictly follow the instructions and dosage in the manual. Adjust the usage based on the size of the plants and the severity of pest infestations. Excessive use may cause damage or even death to plants.
2. Regular inspection:
After use, the growth status of plants should be checked regularly. If the pest problem does not improve or worsens, the use of imidacloprid should be immediately stopped and other solutions sought.
3. Combination of multiple methods:
Although it is an effective insecticide, relying solely on imidacloprid may lead to insect resistance. Therefore, other prevention and control methods such as biological control, physical control, etc. should be combined to comprehensively address the problem of flower pest infestations.
Human exposure and toxicity:
The most common clinical symptoms include rash, difficulty breathing, headache, eye tears, nausea, itching, dizziness, increased saliva secretion, vomiting, numbness, and dry mouth. A case was reported where a worker splashed imidacloprid into the eyes. The clinical symptoms are a burning sensation in the eyes and corneal abrasions. The intramuscular injection blood drug concentrations found in the two death cases were 12.5 and 2.05 ug/mL, respectively. The damage induced by imidacloprid (IM) in HepG2 cells is caused by the fragmentation effect of this insecticide.
Animal research:
IM (purity, 94.2%) does not irritate the eyes or skin of rabbits, nor does it make the skin of guinea pigs sensitive. Single dose oral intramuscular injection has moderate toxicity in rats and mice. Behavioral and respiratory signs, movement disorders, eyelid stenosis, transient tremors, and spasms were observed in rats and mice treated orally at doses greater than or equal to 200 mg/kg body weight and/or greater than or equal to/71 mg/kg body weight, respectively.
Clinical symptoms reverse within 6 days. In chronic experiments conducted in rats, the liver was the main target organ, and only hepatic cell hypertrophy and sporadic cell necrosis were observed in high-dose males. At the end of the study, liver pathology was mild and completely reversible during the recovery period. Male rats treated with IM showed histopathological changes in the testes and epididymis. In developmental studies of rats, a high proportion of male fetuses were observed, and an increased incidence of wavy ribs was observed.
In a study of developing rabbits, high-dose fertility was reduced based on observed miscarriage, total litter product absorption, and increased post implantation losses due to increased late stage absorption. However, this dosage level also leads to weight loss and weight gain, and increases mortality rates.
Early developmental exposure to IM has both early and sustained effects on the neurobehavioral function of zebrafish. Diaper rats with 170 mg/kg intramuscular injection, and measure chromosomal structural abnormalities, abnormal cells, and mitotic index under a microscope in bone marrow cells. Male rats are more susceptible to the genotoxic effects of imidacloprid.
The impact of IM on beneficial insects such as bees is still controversial. Once nectar with IM traces flows into the hive for distribution, it may damage indoor duties and have a negative impact on bee colony performance. When adult worker bees raised in the laboratory were treated with sublethal doses of IM, TUNEL technology was used to detect neuronal apoptosis for DNA labeling. The behavioral effects of IM and 5-OH-IM were studied using olfactory conditions with a long nose extension response during two periods of the year. The learning performance of winter bees that survived long-term treatment with IM and 5-OH-IM decreased. The lowest concentration of IM effect was observed in summer bees (12ug/kg), lower than in winter bees (48 ug/kg), indicating that summer bees are more sensitive to bee behavior compared to winter bees.
We studied the oral acute and chronic toxicity of IM and its main metabolites (5-hydroxyimidacloprid, 4,5-dihydroxyimidacloprid, nitroimidacloprid, 6-chloronicotinic acid, olefins, and urea derivatives) in bees. Intramuscular injection or acute toxicity of its metabolites can lead to rapid onset of neurotoxic symptoms, such as hyperresponsiveness, hyperactivity, and tremors, and result in delayed response and activity. Compared to untreated bee colonies, the colonies of Bumblebee (Bombusterrestris audak) exposed to IM exhibit defects in colony growth and nest condition.
