What are the similarities and differences between Nitenpyram and Dinotefuran?

       Similarities In terms of the classification of insecticides, both of them belong to nicotine insecticides, and their mechanism of action is to inhibit the process of pest nerve transmission and kill the pests. In addition, both can prevent and control pests such as aphids, thrips, and whiteflies.

　　Differences 1. The way of exerting effects is different: Nitenpyram is mainly used for contact killing in agricultural production, and has a certain stomach poison effect; while Dinotefuran, it has both contact killing and systemic killing effects, as well as stomach poison effects.
　　2. The speed and duration of insecticide are different: Because of the different modes of action, the two also have certain differences in the speed of insecticide. Although both have contact killing effects, nitenpyram has a stronger contact killing effect, and it has the effect of hitting resistant whiteflies and other pests first and then falling off; while dinotefuran can only show obvious effects one or two hours after the drug is applied; in terms of the duration, nitenpyram has almost no duration, while dinotefuran has a duration of about one week.
　　3. The scope of insect control is different: Although both can control aphids, thrips, planthoppers and other pests, dinotefuran has a wider control spectrum than nitenpyram. Dinotefuran can also control leek maggots, mosquitoes, flies, scales, ants, flea beetles, etc., and even dinotefuran can be used as a hygienic drug to control fleas and other pests.
　　4. There are differences in pest resistance: Nitenpyram was launched earlier, and pests are currently severely resistant to it. Dinotefuran is the latest generation of nicotine insecticides, known as "super nicotine insecticides". It was launched later, pest resistance is average, safe and efficient, and more active.
　　5. There are differences in the use of methods: In actual agricultural production, nitenpyram is mainly used for foliar spraying, while dinotefuran is used in more ways. It can be flushed to control underground insects such as leek maggots, or it can be made into granules for spraying to prevent insects. This mainly depends on the systemic insecticide effect. Nitenpyram is mainly contact killing, so flushing is not recommended.
　　How to use? 1. When we actually use the two insecticides, if we want to achieve the insect control effect, when used alone, 20% dinotefuran needs to be used 1000-1500 times to be effective; 30% nitenpyram is recommended to be used 750-1000 times for obvious insect control effect.
　　2. In the high-incidence period of pests, if you want to quickly eliminate pests, it is recommended to use nitenpyram as the main ingredient, but this ingredient must not be used alone, because it has no lasting effect. It is recommended to use it with pymetrozine, spirotetramat, etc.
　　3. In actual use, if it is used against pests such as aphids, thrips, and whiteflies, it is actually recommended to choose dimethomorph instead of nitenpyram. After all, it has a systemic effect, low resistance, and better insect control effect.
　　4. Some growers will also ask, can the two be used together? The answer is definitely yes, but in terms of the mode of action, the combination of the two does not make much sense. It is recommended to use each of them with some oviducts that extend the lasting effect or different mechanisms of action, such as pymetrozine, spirotetramat, thiamethoxam, pyriproxyfen, etc.
　　5. When using dinotefuran to control flea beetles, it is recommended to use it in combination with dacarbam; to control whiteflies, use spirotetramat in combination; to control leek maggots, use chlorpyrifos in combination with flushing; to control aphids, use flonicamid in combination with spraying.
