Embodiment 1

[0022] Example 1: Toxicity determination of cyflufenate, etoxazole and different ratios to Panonychus citrus

[0023] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". Sensitive test insects came from Nanjing Agricultural University. After 30 generations of indoor breeding of female adult mites of Panonychus citrus, the female adult mites with uniform growth were selected as the test insects. The resistance test insects were collected from Sihui City, Guangdong Province, where Panonychus mites have high resistance to spirodiclofen. Female adult mites with uniform growth were selected as the test insects. The test adopts the small seedling method, that is, 50-60 whole claw mites are inoculated on small pots of citrus seedlings, and the base number is checked after 1 day. After the dead mites are picked out, live adult mites are added, and the number of mites per treatment is kept at about 50 . Spray the seedlings with...

Embodiment 2

[0035] Example 2: Toxicity determination of cyflumetate, etoxazole and different ratios to Tetranychus urticae

[0036] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". Sensitive populations come from Tetranychus urticae raised indoors all the year round in the Noposon Research Institute; resistant populations are directly collected from Tetranychus urticae in Longgang area, Shenzhen, and female adult mites with uniform growth are selected as the test insects. Adopt cotton seedling method, test method and statistical method are with embodiment 1.

[0037] The test results are shown in Table 3 and Table 4.

[0038] Table 3 Toxicity determination of cyflufen, etoxazole and different ratios of Tetranychus urticae (susceptible species to etoxazole) (15 days)

[0039]

[0040] Table 4 Toxicity determination (15 days) of cyflufen, etoxazole and different ratios of Tetranychus urticae (to etoxazole resistant population, ...

Embodiment 3

[0043] Example 3: Toxicity determination of cyflumetate, etoxazole and different ratios to Tetranychus cinnabarinus

[0044] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". Female adults of Tetranychus cinnabarinus collected from the field were reared indoors for 30 generations, and the female adults with uniform growth were selected as the test insects. Adopt tomato seedling method, test method and statistical method are with embodiment 1.

[0045] The test results are shown in Table 5.

[0046] Table 5 Toxicity determination of cyflufen, etoxazole and different ratios of Tetranychus cinnabarinus sensitive populations (15 days)

[0047]

[0048] It can be seen from Table 5 that when the weight ratio of cyflumet and etoxazole is mixed in the range of 30:1 to 1:30, the co-toxicity coefficient of each ratio reaches above 120, showing a certain synergistic effect.

Abstract

The invention relates to a pesticide composition for preventing and treating drug-fast tetranychid mites, which is used for preventing and treating pest mites on crops, and especially can be used for preventing and treating panonychus citri, two-spotted spider mites and tetranychus cinnabarinus. The active components of the composition are cyflumetofen and etoxazole, wherein the mass ratio of the cyflumetofen to the etoxazole is 30:1-1:30, and the composition can be prepared into various forms including missible oil, microemulsions, EW (emulsions in water), suspending agents, wettable powder, water dispersible granules, microcapsule suspending agents and suspoemulsions.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing cyflufenate and etoxazole, which is used for preventing and controlling harmful mites in agriculture. Background technique [0002] At present, in the control of agricultural pest mites, due to the many generations of pest mites, rapid reproduction, and easy resistance, some acaricide varieties with good control effects, such as abamectin and pyridaben, have been used for many years. , the acaricide effect is significantly reduced or the effective control time of one application is very short, even for newly developed acaricides, if resistance prevention measures are not taken, resistance will usually develop quickly. By continuously increasing the frequency of use of pesticides and increasing the concentration of pesticides used, the ideal control effect cannot be achieved, and the poisonous pollution to people and the environment has also increased. ...
