Embodiment 1

[0026] Example 1: The compounded insecticidal and acaricidal composition of cyflumet and diazinon

[0027]Table 1 Indoor determination results of the composition of cyflumet and diazinon against Tetranychus cinnabarinus

[0028]

[0029] As can be seen from the test results in Table 1, the compounded insecticidal and acaricidal compositions of cyflufenfen and diazinon have a co-toxicity coefficient greater than 120 in the range of 1 to 30: 30 to 1 (by weight). , showing a synergistic effect on cinnabar leaves. It is reasonable and feasible to mix the two.

Embodiment 2

[0031]

[0032] The above formulations are mixed in proportion, sheared and jet milled to prepare 10% wettable powder of cyflumetofen and diazinon.

[0033] This embodiment 2 is applied to control citrus spider mite, and the control effects are 84.87% and 90.97% respectively 3 days and 7 days after the application. As a control single dose of cyflumetate SC was applied in the same way, the control effects were 78.23% and 82.68% at 3 days and 7 days after application. The synergistic effect of the combination of cyflumet and diazinon is obvious, and the control effect is better than that of a single agent.

Embodiment 3

[0035]

[0036] The above formula is dry pulverized, granulated, dried and sieved according to the proportion to prepare 15% water dispersible granules of cyflumet and diazinon.

[0037] This embodiment 3 is applied to prevent and control apple spider mites, and the control effects are 85.16% and 92.66% respectively after 3 days and 7 days after treatment. As a control, a single dose of cyflumet-methyl SC was applied in the same way, and the control effects were 73.25% and 80.64% 3 days and 7 days after the application, respectively. The synergistic effect of the combination of cyflumet and diazinon is obvious, and the control effect is better than that of a single agent.

Abstract

The invention discloses an insecticidal and acaricidal composition for agricultural pests, the insecticidal and acaricidal composition contains two active components, the first active component is cyflumetofen, the second active component is diazinon, the weight ratio of the first active component to the second active component is (1-30): (30-1), and the insecticidal and acaricidal composition is compounded by the active components and other auxiliaries. The insecticidal and acaricidal composition disclosed by the invention is suitable for preventing and treating insects such as mites, flies, defoliators, chilo suppressalis and rice planthoppers on crops such as fruit trees, vegetables and rice. The insecticidal composition is superior to a single agent in the aspects of fast-acting property and persistence, overcomes the defects of the single agent pesticide, delays the generation of pest resistance to drugs, improves the pesticide effect, expands the prevention and treatment spectrum, reduces the use dosage and the use cost of the pesticide, can alleviate the pollution to the environment, and is beneficial to environmental protection and comprehensive treatment of agricultural pests.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a pesticide composition compounded by cyflufenofen and diazinon and a preparation method thereof. The preparation is used for preventing and controlling agricultural pests. Background technique [0002] Insecticides and acaricides developed and marketed in the 1990s have become increasingly serious problems due to long-term unscientific use of pesticide residues, environmental toxicity, and pest resistance. Some pesticides have even produced cross-resistance among pests. The 3R (resistance, re-emergence, residue) problem of pesticide chemical control is a global problem. In recent years, with people's increasing requirements and emphasis on environmental ecology and food safety, some traditional insecticides and acaricides are restricted and affected by toxicity, residues, environmental factors and resistance. , has been banned and restricted in many countries and regions. ...
