Embodiment 1
[0015] Example 1: 12% tetraprole·matrine (1:5) wettable powder
[0016] Proportion (by weight): 2% of chlorfenapyr, 10% of matrine, 5% of pull-off powder, 3% of dispersant NNO, 2% of sodium lignosulfonate, and 100% of kaolin.
[0017] Preparation method: first use filler to absorb matrine, then add other raw materials to mix evenly, and then crush by airflow to obtain wettable powder.
Embodiment 2
[0018] Example 2: 25% tetraprole·matrine (4:1) wettable powder
[0019] Proportion (weight ratio): 20% of chlorfenapyr, 5% of matrine, 7% of pull-off powder, 3% of dispersant NNO, 2% of sodium lignosulfonate, and 100% of kaolin.
[0020] Preparation method: first use filler to absorb matrine, then add other raw materials to mix evenly, and then crush by airflow to obtain wettable powder.
Embodiment 3
[0021] Example 3: 18% tetraprole·matrine (5:1) wettable powder
[0022] Proportion (weight ratio): 15% of chlorfenapyr, 3% of matrine, 6% of pull-off powder, 3% of dispersant NNO, 3% of sodium lignosulfonate, and 100% of kaolin.
[0023] Preparation method: first use filler to absorb matrine, then add other raw materials to mix evenly, and then crush by airflow to obtain wettable powder.
[0024] The effect will be described below with reference to test examples.

Abstract
The invention discloses insecticide and acaricide composition containing flufiprole and matrine. The composition is prepared through compounding of the flufiprole and the matrine in the mass ratio being (0.2-20):1, and the total content of effective components ranges from 1% to 80%. The flufiprole and matrine compound has the effect of synergistic interaction in the aspects of preventing and controlling Tetranychus cinnabarinus and Aphis gossypii, the bactericide spectrum is expanded effectively, the consumption of the effective components is reduced, the environmental pollution is reduced, the drug resistance of pests is delayed, and the effects of preventing and treating multiple targets through one-time drug application and reducing the preventing and treating cost are realized.
Description
technical field [0001] The invention relates to an insecticidal and acaricidal composition containing chlorfenapyr and matrine, belonging to the technical field of pesticides. Background technique [0002] Flufiprole (flufiprole), chemical formula: C 16 h 10 C l2 f 6 N 4 OS, chemical name: 1-(2,6-dichloro-a,a,a-trifluoro-p-tolyl)-5-methallylamino-4-(trifluoromethylsulfinyl)- Pyrazole-3-carbonitrile is a broad-spectrum insect growth regulator of pyrazoles. The insecticidal mechanism is novel, unique and highly active. It mainly hinders the chloride metabolism controlled by insect γ-aminobutyric acid. It has stomach toxicity, contact killing and certain systemic effects. It can be applied to rice, cotton, vegetables, corn, fruit trees, etc. It can control larvae and adults of Lepidoptera, Coleoptera, Hemiptera, etc. on crops. It has a long duration of effect, especially the activity against rice and vegetable pests has shown the same efficacy as fipronil, and it is low i...
