Embodiment 1

[0022] Example 1: Toxicity determination of cyflufenofen, profenofos 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". The female adults of Panonychus citrus collected from the field were reared indoors for three generations, and the female adults with uniform growth were selected as the test insects. The small seedling method is used, 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 mites using a spray tower, move them to culture at 25°C and 90% relative humidity, check under the microscope after 15 hours, record the number of survivors, use DPS data processing software for statistical analysis, and calculate LC 50 , The joint action method adopt...

Embodiment 2

[0032] Example 2: Determination of the toxicity of cyflufenate, quinalfos and different ratios to Tetranychus urticae

[0033] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". Female adults of Tetranychus urticae collected from the field were reared indoors for three generations, and the female adults with uniform growth were selected as the test insects. Adopt cotton seedling method, test method and statistical method are with embodiment 1.

[0034] The test results are shown in Table 2.

[0035] Table 2 Toxicity determination (15 days) of cyflufen, quinalfos and different ratios of Tetranychus urticae

[0036]

[0037] It can be seen from Table 2 that when the weight ratio of cyflumet and quetiafos is mixed between 20:1 and 1:50, the co-toxicity coefficient of each proportion has reached more than 120, showing a certain synergistic effect; When the weight ratio of cyflumet and quetiafos is mixed between 1:1 and...

Embodiment 3

[0038] Example 3: Toxicity determination of cyflumetate, triazophos and different ratios to Tetranychus cinnabarinus

[0039] 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 three 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.

[0040] The test results are shown in Table 3.

[0041] Table 3 Toxicity determination of cyflumet, triazophos and different ratios of Tetranychus cinnabarinus (15 days)

[0042]

[0043] It can be seen from Table 3 that when the weight ratio of cyflumet and triazophos is mixed in the range of 20:1 to 1:50, the co-toxicity coefficient of each ratio reaches above 120, showing a certain synergistic effect.

Abstract

The invention relates to a synergistic pesticide composition. The active ingredients of the composition are cyflumetofen and an organophosphorus insecticide, wherein the weight ratio of the cyflumetofen to the organophosphorus insecticide is 20:1-1:50, and the two active ingredients are prepared into various forms including missible oil, microemulsions, EW (emulsions in water), suspending agents, microcapsule suspending agents and suspoemulsions. The composition is used for preventing and controlling pest mites of crops, and especially can be used for preventing and controlling panonychus citri mcgregor and tetranychus urticae koch; and the composition has a synergistic effect, is quick-acting and long-acting, and can reduce consumption of pesticide, save manpower, and contribute to delaying the development of insect resistance.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing cyflumetate and an organophosphorus insecticide, which is used for preventing and controlling agricultural pests and harmful mites. Background technique [0002] Organophosphorus is an important class of pesticides. At present, organophosphorus pesticides still occupy the first place in the amount of pesticides used in my country. The gradual replacement or partial replacement of highly toxic organophosphorus pesticides is part of the structural adjustment of pesticide varieties in my country. There are many generations of harmful mites on agricultural crops, fast reproduction, and easy to develop resistance. Some acaricides with good control effects, such as avermectin and pyridaben, have been used for many years, and their acaricidal effect has decreased significantly. Or the effective control time of one application is very short. By continuously ...
