Dinotefuran is a representative of the third-generation neonicotinoid insecticides. Similar to traditional neonicotinoid insecticides, it acts on the central nervous system of insects, causing paralysis and eventually leading to pest death. It has contact, stomach poisoning, and excellent systemic translocation activity. Dinotefuran is widely used in agriculture for effective control of pests on rice, cotton, vegetables, fruit trees, flowers, and other crops. It is also highly effective against sanitary pests such as cockroaches, termites, and houseflies.
Dinotefuran Features
1. Broad Insecticidal Spectrum
Dinotefuran provides highly effective control of pests from Hemiptera, Lepidoptera, Diptera, and other orders on crops such as wheat, rice, cotton, vegetables, fruit trees, and flowers.
2. Excellent Control of Piercing-Sucking Pests
Dinotefuran exhibits strong insecticidal activity even at low application rates and is especially effective against piercing-sucking pests. It is mainly used to control aphids, leafhoppers, planthoppers, whiteflies, and similar pests.
3. No Cross-Resistance
Dinotefuran belongs to the third generation of neonicotinoid insecticides and has no cross-resistance with many other insecticides. In addition, it provides better control of pests that have already developed resistance to conventional neonicotinoids.
4. Long Residual Activity
The residual control period of Dinotefuran can last 4–8 weeks (theoretically up to 43 days), providing thorough pest control and reducing the likelihood of reinfestation.
5. High Activity and Strong Penetration
Dinotefuran has excellent penetration ability and can effectively move from the leaf surface into plant tissues. Even in dry soil conditions (with soil moisture as low as 5%), granular formulations can still deliver stable performance.
6. Fast Action
After application, Dinotefuran is rapidly absorbed by crops and widely distributed throughout flowers, leaves, fruits, stems, and roots. When sprayed on both the upper and lower leaf surfaces, it can effectively achieve "top-to-bottom" and "bottom-to-top" control. Compared with other neonicotinoid products, the greatest advantage of Dinotefuran is its much higher water solubility. Its water solubility is 8 times higher than second-generation neonicotinoids and 80 times higher than first-generation neonicotinoid products, meaning Dinotefuran is more easily absorbed by plants.
Application Methods and Precautions
1. Application Methods
Dinotefuran can be used for seed treatment, foliar spraying, and soil application.
An 8% Dinotefuran flowable seed coating formulation can be used for seed treatment on wheat, corn, peanuts, potatoes, and other crops at a dosage of 1450–2500 g per 100 kg of seeds. It effectively controls piercing-sucking pests during the seedling stage, such as aphids, whiteflies, and tobacco whiteflies, while also controlling underground pests including grubs and wireworms.
Applying 15–30 kg/ha of 3% Dinotefuran granules through broadcasting, furrow application, or hole application can effectively control aphids, whiteflies, tobacco whiteflies, leafhoppers, and other pests, with residual efficacy lasting more than 50 days.
2. Safety Precautions
Although Dinotefuran is relatively safe for mammals, it is highly toxic to bees and silkworms. Therefore, it should not be used near apiaries, mulberry trees, or nectar-producing crops. In addition, due to its long residual activity, the recommended pre-harvest interval and safety interval should be strictly observed.
3. Compatibility and Resistance Management
Dinotefuran should not be mixed with alkaline pesticides or substances such as Bordeaux mixture and lime sulfur. During application, it is recommended to rotate, alternate, or tank-mix Dinotefuran with insecticides of different modes of action to improve pest control efficacy and delay the development of pest resistance.
