Dinotefuran

Dinotefuran is an organic compound with molecular formula of C7H14N4O3, molecular weight of 202.2111 and melting point of 107.5 ℃. It is mainly used as insecticide. Due to the difference in structure with other nicotinic insecticides, furabendam is also different from nicotinic insecticides in performance, which is called "Nitrofuran nicotine". It has no cross resistance with other nicotinic insecticides, and has the effect of contacting and killing stomach toxicity, at the same time, it also has good imbibition. It has the characteristics of high quick acting, high activity, long duration and wide insecticidal spectrum, and has excellent control effect on piercing sucking apparatus pests, especially on rice planthopper, Bemisia tabaci, whitefly and other pests that have developed resistance to imidacloprid. The insecticidal activity was 8 times of that of the second generation and 80 times of that of the first generation.

Physical and chemical properties:

White crystalline solid. The melting point is 107.5 ℃. The boiling point is 208 ℃. The vapor pressure is less than 1.7 × 10-3 MPa (30 ℃). KowlgP-0.549（25℃）。 Henry constant is 8.7 × 10-9pa · m3 / mol (calculated value). The relative density is 1.40. 8 g / L (20 ℃). Solubility in organic solvent (g / L, 20 ℃): hexane 9.0 × 10-6, heptane 11 × 10-6, xylene 72 × 10-3, toluene 150 × 10-3, dichloromethane 11, acetone 58, methanol 57, ethanol 19, ethyl acetate 5.2. It was stable at 150 ℃, hydrolyzed DT50 > 1 year (pH 4,7,9), and photodegradated DT50 > 3.8 H (disinfected water / natural water). pKa 12.6（20℃）.

Mechanism of action:

Dinotefuran reaches the action point in the form of free base, and it can disturb the neurotransmitter system of insects by binding with nicotinic acetylcholine receptor and paralyze insects. The results showed that the binding activity of furabendam to acetylcholine receptor was lower than that of other nicotinic insecticides, but its efficacy was higher than that of other nicotinic insecticides. It was suggested that there were different binding sites of furabendam, which might be caused by the special furan structure in furabendam, resulting in the different action mechanism between furabendam and other nicotinic insecticides There was no cross resistance to insecticides.

Compound preparation:

CAS：165252-70-0

Product category: pesticide raw materials

Properties of technical drug:

technical drug is white powder, insoluble in water. It is stable at room temperature.

Applied crops:

Rice, wheat, vegetables, fruit trees, tea, cotton, tobacco and other crops.

Prevention and control objectives:

It is mainly used to control all kinds of Planthopper, stink bug, whitefly, leafhopper, leaf miner, thrips, flea beetle, mealybug, aphid, leaf miner, peach fruit moth, rice borer, Plutella xylostella, Pieris rapae, and other health pests, such as flea, cockroach, termite, housefly, mosquito, etc.

explain:

It belongs to the third generation of nicotine insecticides.

Compared with the first and second generation insecticides, it has a wider insecticidal spectrum and is more convenient to use, and can overcome the resistance risk brought by the first and second generation insecticides.
