Problems solved by technology

[0003] However, the level of pesticide oil suspension concentrates in my country is relatively backward now, and there are often problems such as unsatisfactory drug efficacy, layering of preparations, decomposition of the original drug, product precipitation and agglomeration, non-dispersion or unsatisfactory dispersion, freezing in winter and inability to produce and use, etc. , which greatly limits the development of this dosage form

Embodiment 1

[0019] A kind of tebufenozide oil suspension insecticide, is made up of the composition of following percentage by weight:

[0020] 20% tebufenozide, 0.2% bentonite, 25% AEO-3, and the rest soybean oil.

[0021] Results: 1. The dosage form is stable, and it can be stored at room temperature for 2-3 years; 2. The degradation rate of active ingredients is low. The average degradation rate is 0.6% when stored in heat at 52℃±2 for 15 days; when stored in cold storage at -10℃±2 for 15 days. No freezing, no crystallization; 3. Remarkable synergistic effect, up to 70%.

Embodiment 2

[0023] A kind of tebufenozide oil suspension insecticide, is made up of the composition of following percentage by weight:

[0024] 15% tebufenozide, 0.1% bentonite, 20% AEO-3, and the rest soybean oil.

[0025] Results: 1. The dosage form is stable, and it can be stored at room temperature for 2-3 years; 2. The degradation rate of active ingredients is low. The average degradation rate is 0.7% when stored in heat at 52℃±2 for 15 days; when stored in cold storage at -10℃±2 for 15 days. No freezing, no crystallization; 3. Significant synergy, up to 55%.

Embodiment 3

[0027] A kind of tebufenozide oil suspension insecticide, is made up of the composition of following percentage by weight:

[0028] 25% tebufenozide, 0.3% bentonite, 30% AEO-3, and the rest soybean oil.

[0029] Results: 1. The dosage form is stable, and it can be stored at room temperature for 2-3 years; 2. The degradation rate of active ingredients is low. The average degradation rate is 0.7% when stored in heat at 52℃±2 for 15 days; when stored in cold storage at -10℃±2 for 15 days. No freezing, no crystallization; 3. Remarkable synergistic effect, up to 60%.

Abstract

The invention discloses a tebufenozide oil suspension pesticide and a preparation method thereof. The pesticide comprises the following components by weight percent: 15-25% of tebufenozide, 0.1-0.3% bentonite, 20-30% of AEO-3 and the balance of soybean oil. The preparation method comprises the steps of pre-crushing and mixing and superfine grinding. The pesticide has the advantages that the formulation is stable, the synergism is obvious, the permeability and systemic performance of active ingredients are improved, the pesticide is suitable for various atomizing technologies, and the preparation method is simple.

Description

technical field [0001] The invention relates to a suspending agent insecticide, specifically a tebufenozide oil suspending agent insecticide and a production process thereof, belonging to the field of suspending agent insecticides. Background technique [0002] Oil suspension refers to one or more active ingredients of pesticides (at least one of which is a solid original drug) to form a highly dispersed and stable suspension system in a non-aqueous dispersion medium. The English name of oil suspension is Oil miscible flowable concentrate. It is abbreviated as OF and referred to as oil suspension in Chinese. The development of oil suspension began in the late 1970s and developed rapidly in the 1980s. [0003] However, the level of pesticide oil suspension concentrates in my country is relatively backward now, and there are often problems such as unsatisfactory drug efficacy, layering of preparations, decomposition of the original drug, product precipitation and agglomeration...
