Description

Insecticidal composition containing bromofenoxaprop-p-fluorobenzene bisamide and chlorantraniliprole
Technical Field
The invention belongs to the field of agricultural chemistry, and particularly relates to an insecticidal composition containing bromofenoxynil fluorobenzene bisamide and chlorantraniliprole.
Background
Plutella xylostella (L.) is one of the main pests of cruciferous crops, is distributed all over the country, and is serious in vegetable production areas. The existing control of the plutella xylostella still depends on chemical pesticides, and the plutella xylostella is easy to generate resistance to the pesticides due to frequent application of the chemical pesticides and the characteristics of short generation and rapid propagation of the plutella xylostella. According to the report, the diamondback moth in China has resistance to more than 90% of medicaments, the prevention and control situation is severe, and the resistance problem becomes an important obstacle for restricting the development of the cruciferous vegetable industry in China.
The development area of the drug resistance is gradually enlarged from point to surface, and the development level of the drug resistance is from low to high. Relevant studies have shown that resistance to diamondback moth is not stable from low to very high levels of resistance, but tends to stabilize after very high levels of resistance are reached. Therefore, when the drug resistance occurrence area is small and the drug resistance level is relatively low, a scientific and reasonable medication strategy is made in time, the selection pressure of the drug is reduced, and the method is particularly important for prolonging the service life of the drug and delaying the generation of the drug resistance.
The diamondback moth is one of the most serious pests with drug resistance in the world, has strong environment adaptability and resistance generation capability, and is difficult to thoroughly solve the problem of drug resistance only by using a new target pesticide to treat the resistant diamondback moth. Avoiding long-term use of a single agent, reducing the dosage of the single agent is an effective means for controlling the resistance problem of the diamondback moth, and is beneficial to delaying the generation of drug resistance.
Chlorantraniliprole is the first broad-spectrum pesticide with a novel o-acylaminobenzamide chemical structure, can effectively control almost all important lepidoptera pests and partial other pests, and is very safe to crops. The brofenpyrad fluorobenzene bisamide is a novel bisamide insecticide jointly developed by Mitsui agricultural chemical company and Pasteur in Japan, and is mainly used for controlling lepidoptera and coleoptera pests of leafy vegetables, cereals and other perennial crops, and sanitary pests such as termites, mosquitoes, flies and the like. In the prior art, no related report that the pesticide is compounded to delay the pesticide resistance of pests is provided.

Detailed Description
The following detailed description of specific embodiments of the present invention is provided in conjunction with examples, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Indoor bioassay: indoor insecticidal toxicity determination method of diamondback moth by using brotrochan fluorobenzene diamide and chlorantraniliprole
The test object is plutella xylostella, and cabbage leaves are artificially bred for multiple generations indoors without contacting any medicament; and selecting 3-instar larvae.
The test method comprises the following steps: test agents were formulated in 5 series of concentrations on a pre-test basis. Beating the clean cabbage leaves into round pieces with the diameter of 2cm by using a puncher, immersing the leaves into corresponding medicaments, treating for 10s, taking out and airing. The leaves with the drug are placed in a 12-well plate and then 3-instar larvae of the same size are inoculated. Each treatment was repeated 4 times with 10 replicates. And (4) checking the death condition after 48h, judging the death condition by no reaction when the brush is slightly touched on the body surface of the larva, recording the death number and survival number, and calculating and correcting the death rate. Performing data analysis by adopting a sps software; the co-toxicity coefficient (CTC) of the drug was then calculated according to the Sun cloud Peel method. When the CTC is less than or equal to 80, the composition shows antagonism, when the CTC is more than 80 and less than 120, the composition shows additive action, and when the CTC is more than or equal to 120, the composition shows synergistic action.
TABLE 1 indoor insecticidal virulence determination of Imidacloprid flubendiamide and chlorantraniliprole against plutella xylostella
As shown in Table 1, compared with a single agent, the weight ratio of the brotrochan fluorobenzene diamide to the chlorantraniliprole in the insecticidal composition is in a range of 1:10-20:1, the composition has excellent insecticidal activity on cabbage diamondback moths, and the composition has a remarkable synergistic effect.
And (3) field pesticide effect determination:field control effect determination of diamondback moth by using brofenthiuron bisamide and chlorantraniliprole
Test subjects: cabbage diamondback moth
