Embodiment 1

[0027] Embodiment 1: the emulsifiable concentrate of triflumuron containing combination synergist

[0028] Based on the total mass fraction of 100%, including insecticide: 5% trifluron, synergist: 0.5% salicylic acid, synergist: 0.8% triphenyl phosphate, emulsifier: alkylphenol polyoxyethylene Ether (NP-10) 5%, co-solvent: ethylene glycol 5%, solvent: dimethylformamide supplemented to 100%. Preparation method: put the insecticide, synergist, emulsifier, co-solvent, and solvent into the mixer in sequence, stir for 30 minutes, and fill the finished product after the emulsifiable oil is clear and transparent.

Embodiment 2

[0029] Embodiment 2: Contain the suspension concentrate of triflumuron of combination synergist

[0030] Based on the total mass fraction of 100%, it includes, insecticide: 20% of slumuron, synergist: 0.5% of salicylic acid, synergist: 25% of triphenyl phosphate, emulsifier: 10% of tea saponin, Solvent: cyclohexanone 15%, co-solvent: ethylene glycol 5%, filler: white carbon black 1%, water to make up to 100%. Preparation method: put the insecticide, synergist, emulsifier, co-solvent, solvent, and appropriate amount of water into the reaction kettle in sequence, and use a high-speed shearing machine to shear and emulsify for 30 minutes. Then add filler and water to make up to 100%, and then carry out high-speed shear emulsification for 1 hour, filter out the sediment after the suspending agent is uniform, and fill the finished product.

Embodiment 3

[0031] Embodiment 3: Contain the suspension concentrate of triflumuron of combination synergist

[0032]Based on 100% of the total mass fraction, it includes insecticide: 40% of slumuron, synergist: 15% of salicylic acid, synergist: 0.5% of triphenyl phosphate, emulsifier: 15% of tea saponin, Solvent: cyclohexanone 15%, co-solvent: ethylene glycol 5%, filler: white carbon black 0.5%, water to make up to 100%. Preparation method: Put the insecticide, synergist, emulsifier, co-solvent, solvent, and appropriate amount of water into the reaction kettle in sequence, and use a high-speed shearing machine to shear and emulsify for 30 minutes. Then add filler and water to make up to 100%, and then carry out high-speed shear emulsification for 1 hour, filter out the sediment after the suspending agent is uniform, and fill the finished product.

Abstract

The invention discloses a combined synergistic agent for carbamide pesticides and an environment-friendly pesticide containing the same. The combined synergistic agent comprises salicylic acid and triphenyl phosphate; the laboratory test and the field test show that two types of carbamide pesticides have obvious synergistic effect through combining salicylic acid and triphenyl phosphate and then compounding with triflurnuron or hexaflumuron, so that the time of killing pests by triflurnuron can be shorted, the insecticidal activity of hexaflumuron is improved, pests can be prevented from damaging crops, and the usage amount of the pesticide can be reduced while the equivalent prevention effect is achieved; the synergistic effect of the combination of salicylic acid and triphenyl phosphateused as a synergistic agent on triflurnuron or hexaflumuron is remarkably better that of salicylic acid which is used as a synergistic agent individually and that of salicylic acid which is used as asynergistic agent individually, and the salicylic acid and triphenyl phosphate have a synergism effect.

Description

Technical field: [0001] The invention relates to a pesticide synergist and a pesticide containing the synergist, in particular to a combined synergist of urea pesticides and an environment-friendly pesticide containing the combined synergist. Background technique: [0002] With the improvement of people's awareness of environmental protection and the development of science and technology, specific pesticides such as insect growth regulators have been greatly developed. Among them, chitin synthesis inhibitors are widely used, and these pesticides act on the metamorphosis of insects. , can hinder the formation of new cuticles of insects, and inhibit insects from molting to death, with a unique mechanism. Compared with other chemical pesticides, it has the following advantages: 1) Strong selectivity, safe for humans, animals and natural enemies. 2) Little impact on the ecological environment. [0003] Urea is a kind of chitin synthesis inhibitor pesticide with the largest pro...
