Embodiment 1

[0023] Example 1: Toxicity determination of cyflumetate, mineral oil and different ratios to Panonychus citrus

[0024] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". Sensitive test insects were female adults of Panonychus citrus collected from outdoor osmanthus trees and reared indoors for more than ten generations. Female adults with uniform growth were selected as 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 mites using a spray tower, move them to culture at 25°C and 90% relative humidity, check under the microscope after 15 days, record the number of survivors, use DPS data processing software for statistical analysis, and calcul...

Embodiment 2

[0034] Example 2: Toxicity determination of cyflumetate, mineral oil and different ratios to Tetranychus urticae

[0035] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". The experimental population came from the Tetranychus urticae that was reared indoors all year round in the Noposon Research Institute, and the female adult mites with uniform growth were selected as the test insects. Adopt cotton seedling method, test method and statistical method are with embodiment 1. The test results are shown in Table 2.

[0037]

[0038] Mineral oil: commercially available Total FluidGenera9 mineral oil.

[0039] It can be seen from Table 2 that when the weight ratio of cyflufenofen and mineral oil is mixed between 1:1 and 1:300, the co-toxicity coefficient of each ratio has reached more than 120, and the ...

Embodiment 3

[0040] Example 3: Toxicity determination of cyflumetate, mineral oil and different ratios to Tetranychus cinnabarinus

[0041] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". The female adult mites of Tetranychus cinnabarinus collected from the field were reared indoors for more than ten 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. The test results are shown in Table 3.

Abstract

The invention relates to a pesticide composition which is used for preventing and controlling crop mites, especially panonychus, tetranychus urticae koch and tetranychus cinabarinus boisdu. The composition comprises the following effective ingredients: cyflumetofen and mineral oil, wherein the mass ratio of the cyflumetofen to the mineral oil is (1 to 1) to (1 to 300). The composition can be prepared into various formulations including missible oil, an emulsion in water and a suspension emulsion.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing cyflumetate and mineral oil, 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...
