[0022] Bentonite make up to 100%

[0023] After the above-mentioned components are accurately weighed in proportion, after mixing, they are crushed by air flow, mixed again, extruded and granulated to prepare water-dispersible granules.

[0024] In this embodiment, the weight ratio of nitenpyram to buprofezin can vary between 0.01-100:1 (for example 0.01:1, 1:1, 10:1, 100:1), and the total weight percentage of the two Can change between 0.01-95, form new embodiment.

[0025] It is also possible to replace buprofezin with an active substance among chlorpyrifos, pymetrozine, thiamethoxam, fipronil, thiacloprid, and...

Embodiment 2

[0027] Example 2 25% nitenpyram buprofezin aqueous suspension, the formula is as follows:

[0028] Nitenpyram 5%

[0029] Buprofezin 20%

[0030] Synergist (such as azone) 1-2%

[0031] Diffusion agent NNO (naphthalenesulfonic acid formaldehyde condensate sodium salt) 5%

[0032] Phenylphenol polyoxyethylene ether formaldehyde condensate 2%

[0033] Sodium lignosulfonate 3%

[0034] Ethylene glycol 4%

[0035] Sodium Benzoate 0.1%

[0036] Silicone defoamer 0.2%

[0037] Water make up to 100%

[0038] The above-mentioned components are accurately weighed in proportion, mixed evenly, and subjected to colloid mill and sand mill to prepare a suspending agent.

[0039] In this embodiment, the weight ratio of nitenpyram to buprofezin can vary between 0.01-100:1 (for example 0.01:1, 1:1, 10:1, 100:1), and the total weight percentage of the two Can change between 0.01-95, form new embodiment.

[0040] It is also possible to replace buprofezin with an active substance among ...

Embodiment 3

[0042] Example 3 20% Nitenpyram·Pymetrozine microemulsion, the formula is as follows:

[0043] Nitenpyram 5%

[0044] Pymetrozine 15%

[0045] Synergist (such as azone) 1-2%

[0046] Dimethylformamide 40%

[0047] Phenylphenol polyoxyethylene ether formaldehyde condensate 14%

[0048] Calcium dodecylbenzenesulfonate 5%

[0049] Water make up to 100%

[0050] After the above-mentioned components except water are accurately weighed in proportion, they are fully stirred evenly, and finally water is added in high shear to make a microemulsion.

[0051] In this embodiment, the weight ratio of nitenpyram to pymetrozine can vary between 0.01-100:1 (for example, 0.01:1, 1:1, 10:1, 100:1), and the total weight percentage of the two Can change between 0.01-95, form new embodiment.

[0052] It is also possible to replace pymetrozine with an active substance among chlorpyrifos, buprofezin, thiamethoxam, fipronil, thiacloprid, and dinotefuran to form a new embodiment.

Abstract

The invention relates to a composition of novel nicotinamide insecticide nitenpyram. The preparation of the composition is a binary composition containing nitenpyram and the other insecticide. The other insecticide is buprofezin, pymetrozine, chlorpyrifos, thiamethoxam, fipronil, thiacloprid, dinotefuran, and the like. The preparation can be processed into new formulations of water dispersible granule, wettable powder, aqua, aqueous emulsion, soluble powder, colloidal suspension agent, and the like, wherein water is used as a solvent, an organic solvent is not used or used less so that the preparation has low toxicity and low residue and is environment-friendly. The nicotinamide insecticide is made of plant source farm chemical nicotinamide, and mainly acts on an acetylcholin esterase receptor of pests and the central nervous system of insects, thus the nicotinamide insecticide has high efficiency and selectivity and is safe to mammals. Compounded with other insecticides, the nicotinamide insecticide can improve the drug effect and enlarge the serviceable range. The novel nicotinamide insecticide is the optimal variety to replace highly-poisonous organophosphorus and organochlorine insecticides. The preparation of the novel nicotinamide insecticide is applied to controlling piercing mouth parts insects for rice, vegetables and other crops, and has the characteristics of low toxicity, low residue, less dosage, long lasting period, safety and no drug injuries to crops, and the like.

Description

technical field [0001] The invention relates to a new type of neonicotinoid insecticide, the composition of which adopts the compounding technology of pesticides, improves the drug effect and expands the insecticidal spectrum. Background technique [0002] Nitenpyram: English common name: Nitenpyram, chemical name: (E)-N-(6-chloro-3-pyridylmethyl)-N’-methyl-2-nitrovinylidenediamine. It mainly acts on insect nerves, inhibits the activity of acetylcholinesterase, and acts on cholinergic receptors. It has good systemic and osmotic effects, low toxicity, high efficiency, broad spectrum, moderate duration of effect, no residue, no harm to crops, etc. It can be called a green pesticide. It is mainly used to control insects with sucking mouthparts in rice, vegetables, tea and other crops. [0003] Buprofezin: English common name: buprofezin, chemical name: 2-tert-butylimino-3-isopropyl-5-phenyl-1,3,5-thiadiazin-4-one. The drug is a highly selective insect growth regulator, and i...
