Embodiment 1

[0019] Example 1: Indoor toxicity test of diflubenzuron and flubendiamide on Plutella xylostella.

[0020] Females of Plutella xylostella were collected from the field to lay eggs. Release the female worms into a cylindrical cage (cage diameter 15cm, height 30cm), the inner wall is lined with a layer of wax paper, the outer cover is black cloth, and fed with 8% honey water. The next day, the egg masses were cut out with the wax paper and placed in a petri dish to keep moist. After hatching, they were reared with fresh leaves of Shanghai green leaves cultivated indoors. The temperature of the insect culture room is (25±1)°C, and the photoperiod is 16(L):8(D).

[0021] The test agent used 95% flubendiamide original drug and 97.9% diflubenzuron original drug, and the required preparations were prepared by the R&D Center of Huizhou Zhongxun Chemical Co., Ltd.

[0022] The spot method recommended by NY / T1154.1-2006 was used for determination. Clean the micro-dropper with solvent...

Embodiment 2

[0029] Example 2 (30% diflubenzuron·flubendiamide water dispersible granules)

[0030] Diflubenzuron 25%, flubendiamide 5%, mineral oil 5%, nonylphenol polyoxyethylene ether 4%, sodium diisooctyl succinate sulfonate 5%, sodium lauryl sulfate 2%, Sodium lignosulfonate 6%, naphthalene sulfonate 4%, bentonite make up to 100%. The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare 30% diflubenzuron·flubendiamide water dispersible granules.

[0031] This embodiment is used for preventing and treating rice leaf roller. 30% diflubenzuron·flubendiamide water dispersible granule was diluted 2000 times with water, sprayed at the peak period of rice leaf roller damage, and applied by spraying, 1 day, 3 days, 7 days after the application The control effects were 88.0%, 97.7%, and 98.4%, respectively. 20% flubendiamide water dispersible granules were used at 3000 times and 20% diflubenzuron suspension at 1000 times, and used in the same way...

Embodiment 3

[0032] Example 3 (40% diflubenzuron·flubendiamide water dispersible granule).

[0033] Diflubenzuron 25%, flubendiamide 15%, epoxy soybean oil 8%, sodium diisooctyl succinate sulfonate 3%, sodium dodecylbenzene sulfonate 2%, sodium lignosulfonate 6 %, sodium naphthalene sulfonate formaldehyde condensate 4%, bentonite 3%, polyethylene glycol 2%, kaolin supplemented to 100%.

[0034] The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare 40% diflubenzuron·flubendiamide water dispersible granules.

[0035]This embodiment is used to control Plutella xylostella. 40% diflubenzuron·flubendiamide water dispersible granule was diluted 4000 times with water, sprayed at the beginning of hatching of Plutella xylostella eggs, and applied by spraying method. The efficiency is 90.3%, 96.9%, 100% respectively. 20% flubendiamide water dispersible granule was used at 3000 times and 20% diflubenzuron suspension at 1000 times, and used in the same...

Abstract

The invention discloses a pesticide composition containing chlorbenzuron and flubendiamide. The weight ratio of the chlorbenzuron to the flubendiamide is 30:1-1:30, preferably 30:1-1:1; and the weight sum of the chlorbenzuron and the flubendiamide is 10-70 percent of the weight of the pesticide composition. After the chlorbenzuron and the flubendiamide are compounded, the composition has obvious synergism; and compared with the use amount of single agent, the use amount of the active ingredients of the composition is obviously reduced. The composition is suitable for preventing and controlling crop lepidoptera pests.

Description

technical field [0001] The pesticide composition involved in the present invention uses diflubenzuron and flubendiamide as active ingredients, and is suitable for preventing and controlling crop Lepidoptera pests. Background technique [0002] The problem of resistance to agricultural pests is a global problem and has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical control of pests year after year, the increase in the use of pesticides and the unscientific use of pesticides, the resistance of pests is becoming more and more serious; the types of pests that are resistant are increasing, especially the lepidoptera that is seriously harmful to agricultural production. The order pests have a high degree of resistance and a relatively fast development of resistance, which has become a major problem in chemical control. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues ...
