The invention belongs to the technical field of pesticide, and relates to a pesticide composition containing thiacloprid and Nicoflubrole and application thereof.
Background
Nicoflutrol is a new phenylpyrazole nicotinamide successfully developed and marketed by BayerA fluorine-containing pesticide. Chemical name: 2-chloro-N-cyclopropyl-5- (1- {2, 6-dichloro-4- [1,2,2, 2-tetrafluoro-1- (trifluoromethyl) ethyl]Phenyl } -1H-pyrazol-4-yl) -N-methylnicotinamide. The molecular formula is as follows: c22H14Cl3F7N4And O. The chemical structural formula is as follows:

thiacloprid (Thiacloprid) is an insecticide developed by the cooperation of germany and japan bayer agrichemicals. Chemical name: (3- ((6-chloro-3-pyridinyl) methyl) -1, 3-thiazolin-2-ylidene) cyanamide. The molecular formula is as follows: c10H9ClN4S, the chemical structural formula is as follows:
Figure BDA0003262174250000012
with the continuous change of planting structures and the large-area use of pesticides in production and life. The occurrence degree and the occurrence quantity of insect pests of the plants are improved, and the prevention difficulty is increased. In addition, the drug resistance of pests is continuously improved by using the pesticide in a large area for a long time, so that the dosage is continuously increased, the risk is increased, and the sustainable development is not facilitated. In addition, once a large area of pest outbreak occurs, it is difficult to control. In order to realize green food production and reduce pesticide residue, a pesticide composition which has long pesticide effect and is safe to plants and non-target organisms is urgently needed. In order to overcome and delay the formation and development of drug resistance of plant pests, the same medicament is avoided as much as possible and is used alternately or in a mixed manner with other medicaments, and pesticide compounding is one of the main ways for solving the problem of drug resistance.
Nicoflutrol is a new phenyl pyrazole nicotinamide type fluorine-containing pesticide successfully developed and marketed by Bayer. Thiacloprid has special effect on pests with sucking and chewing mouthparts. The action mechanism is different from that of other traditional insecticides, the pesticide mainly acts on insect nerve postjunctional membranes, is combined with a nicotine acetylcholine receptor to interfere normal conduction of insect nervous systems, causes blockage of nerve channels and causes a large amount of accumulation of acetylcholine, so that the insects are excited abnormally, and are killed by general spasm and paralysis, and the pesticide has stronger contact poisoning, stomach toxicity and systemic action. Is one of the high-efficiency medicaments for preventing and controlling pests with piercing-sucking and chewing mouthparts. However, in actual production, thiacloprid is mainly used for controlling longicorn in forestry and is less used for controlling other plant pests. Through preliminary search of the inventor and the applicant, no report that the thiacloprid and Nicoflubrole are used in combination for preventing and controlling plant pests is found.
The inventor compounds thiacloprid and Nicofluprole, finds that the composition has obvious synergistic effect on various plant pests, and the control effect is obviously better than that of a single agent.
