Problems solved by technology

However, the frequent and excessive use of neonicotinoid insecticides such as imidacloprid has caused very serious resistance problems
The cross-resistance between neonicotinoid insecticides limits the application of this kind of compound insecticides to a certain extent, and also restricts the development of neonicotinoid insecticides

Embodiment 1

[0023] Polyfluorourea (N-(((3,5-dichloro-2-fluoro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl)amino)carbonyl-2 , 6-difluorobenzamide) and cyclopyridam were mixed according to the weight ratio of 60:1~1:60, and the control experiment of Plutella xylostella was carried out. The experimental results are shown in Table 1.

[0025]

[0026] Theoretical toxicity index TTI = ∑ (the toxicity index TI of each single agent × the percentage of single agent in the mixture)

[0027] As can be seen from Table 1, the median lethal concentration LC of Plutella xylostella is 50 They are 9.82ppm and 10.2ppm respectively. In this example, cyclopyrid and polyfluxuron are compounded according to the weight ratio range of 1:60~60:1 to obtain the composition insecticide:

[0028] 1) The measured toxicity index (ATI) is significantly higher than the theoretical toxicity index (TTI)...

Embodiment 2

[0033] Flubenzuron (1-[2-fluoro-4-(2-chloro-4-trifluoromethyl-phenoxy)phenyl]-3-(2,6-difluorobenzoyl)urea) and ring Oxycloprim was mixed according to the weight ratio of 60:1~1:60, and the control experiment of diamondback moth was carried out. The experimental results are shown in Table 2.

[0036] In the table, theoretical toxicity index TTI = ∑ (toxicity index TI of each single agent × percentage of single agent in the mixture)

[0037] As can be seen from Table 2, the median lethal concentration LC 50 They are 9.82ppm and 9.5ppm respectively. In this example, cycloxafamiprid and flubenzuron are compounded according to the weight ratio of 1:60~60:1 to obtain the composition insecticide:

[0038] 1) The measured virulence index (ATI) is significantly higher than the theoretical virulence index (TTI), and even the measured virulence index (ATI) can...

Embodiment 3

[0043] Diflubenzuron (1-(4-chloro-phenyl)-3-(2,6-difluorobenzoyl)urea) and cyclopyridam were mixed according to the weight ratio of 60:1~1:60, and the vegetable Control experiment of diamondback moth. The experimental results are shown in Table 3.

[0045]

[0046] In the table, theoretical toxicity index TTI = ∑ (toxicity index TI of each single agent × percentage of single agent in the mixture)

[0047] It can be seen from Table 3 that in this example, the composition insecticide obtained by compounding cyclopyrid and diflubenzuron according to the weight ratio range of 1:60~60:1:

[0048] 1) The measured virulence index (ATI) is significantly higher than the theoretical virulence index (TTI), and even the measured virulence index (ATI) can reach more than twice the theoretical virulence index (TTI).

[0049] 2) The co-toxicity coefficients (C...

Abstract

The cyclopyrid composition insecticide provided by the present invention comprises cyclopyrid and a second active ingredient, and the weight ratio of cyclopyrid to the second active ingredient is 60:1-1:60. The second active ingredient is selected from: benzoylurea-type growth regulators, pyridazinone-type growth regulators, semicarbazone-type insecticides, pyridinamide-type insect growth regulators, and carbamate-type insecticides Any one or any mixture of several. The cyclopyrid compound insecticide of the present invention has a co-toxicity coefficient (CTC) significantly higher than 100, has obvious synergistic and additive effects, and can significantly reduce the amount of pesticide used.

Description

technical field [0001] The invention relates to an agricultural insecticide, in particular to a cyclopyrid insecticidal composition. Background technique [0002] Neonicotinoid insecticides represented by imidacloprid have high insecticidal activity, wide insecticidal spectrum, low toxicity to mammals and aquatic animals, good system properties, appropriate field stability and environmental friendliness , has become an important hot spot for new pesticide creation. However, the frequent and excessive use of neonicotinoid insecticides such as imidacloprid has caused very serious resistance problems. The cross-resistance between neonicotinoid insecticides limits the application of this kind of compound insecticides to a certain extent, and also restricts the development of neonicotinoid insecticides. [0003] Cyclopyrid is a new type of neonicotinoid high activity and low toxicity agricultural insecticide, which has obvious antagonism on nAChR, and is very likely to become a...
